WEBVTT - The Saguaro, Part 1

0:00:03.000 --> 0:00:06.760
<v Speaker 1>Welcome to Stuff to Blow Your Mind, production of iHeartRadio.

0:00:13.000 --> 0:00:14.560
<v Speaker 2>Hey, welcome to Stuff to Blow Your Mind.

0:00:14.600 --> 0:00:17.640
<v Speaker 3>My name is Robert Lamb and I'm Joe McCormick.

0:00:17.680 --> 0:00:20.800
<v Speaker 2>And it is cactus Time here on the podcast. We're

0:00:20.800 --> 0:00:23.120
<v Speaker 2>going to be talking about what is I think arguably

0:00:23.320 --> 0:00:28.360
<v Speaker 2>the most iconic species of cactus. Joe and I were

0:00:28.400 --> 0:00:31.920
<v Speaker 2>actually having a conversation though off mic, trying to decide

0:00:31.960 --> 0:00:36.480
<v Speaker 2>exactly how we are going to agree to pronounce this cactus.

0:00:37.000 --> 0:00:41.760
<v Speaker 2>We are talking about the sowarro cactus, but there are

0:00:41.920 --> 0:00:45.239
<v Speaker 2>different versions of the pronunciation floating around out there, and

0:00:45.320 --> 0:00:48.120
<v Speaker 2>I do want to apologize to my Arizona family for

0:00:48.240 --> 0:00:52.640
<v Speaker 2>not one hundred percent remembering how they were pronouncing it.

0:00:52.920 --> 0:00:54.440
<v Speaker 2>But I feel like I've heard it a number of

0:00:54.480 --> 0:00:56.120
<v Speaker 2>different ways in different places.

0:00:56.360 --> 0:01:00.560
<v Speaker 3>So I was like watching interviews with researchers who work

0:01:00.680 --> 0:01:03.400
<v Speaker 3>on this type of cactus, and what I was hearing

0:01:03.400 --> 0:01:06.319
<v Speaker 3>most often then was so worrow. But then we look

0:01:06.360 --> 0:01:08.280
<v Speaker 3>it up and the dictionary says, well, you can either

0:01:08.319 --> 0:01:13.760
<v Speaker 3>do saguaro or sowara, and so there I'm just kind

0:01:13.800 --> 0:01:16.880
<v Speaker 3>of lost. So we're going with sowarrow because I don't know,

0:01:16.920 --> 0:01:18.640
<v Speaker 3>it seems like we're splitting the difference.

0:01:18.840 --> 0:01:23.080
<v Speaker 2>Yeah, but our apologies if we are doing it wrong here. Certainly,

0:01:24.040 --> 0:01:25.880
<v Speaker 2>if any of you out there have thoughts about how

0:01:25.880 --> 0:01:29.039
<v Speaker 2>it should be pronounced, do right in and we can

0:01:29.040 --> 0:01:31.360
<v Speaker 2>carry on from there. This is probably gonna be, I think,

0:01:31.360 --> 0:01:33.200
<v Speaker 2>a two parter, and this is going to be part one,

0:01:33.280 --> 0:01:36.560
<v Speaker 2>so it's entirely possible our pronunciation will shift between part

0:01:36.560 --> 0:01:38.480
<v Speaker 2>one and part two depending on feedback. We'll see how

0:01:38.520 --> 0:01:38.880
<v Speaker 2>it goes.

0:01:39.120 --> 0:01:41.600
<v Speaker 3>Or maybe we should just use the scientific name the

0:01:41.640 --> 0:01:43.480
<v Speaker 3>whole time, because I think you've got a whole story

0:01:43.520 --> 0:01:44.040
<v Speaker 3>on that, right.

0:01:44.959 --> 0:01:48.480
<v Speaker 2>Yeah, let's talk a little bit about the scientific classification

0:01:48.760 --> 0:01:52.640
<v Speaker 2>for the suarrow. This is something I've been going out

0:01:52.640 --> 0:01:55.280
<v Speaker 2>to Arizona for years and seeing these things, and I've

0:01:55.280 --> 0:01:58.920
<v Speaker 2>always been impressed by them. But I think I should

0:01:58.920 --> 0:02:01.080
<v Speaker 2>certainly have read the scientist name before, but I've just

0:02:01.160 --> 0:02:03.760
<v Speaker 2>kind of let it pass through me, I guess, without

0:02:03.800 --> 0:02:06.720
<v Speaker 2>really thinking about it. And it wasn't until researching this

0:02:06.760 --> 0:02:11.600
<v Speaker 2>episode that I was like, huh, it's called Carnegia, Gigantia

0:02:12.560 --> 0:02:17.919
<v Speaker 2>and Carnegia. Yeah, that's that's an interesting name for this

0:02:17.919 --> 0:02:20.400
<v Speaker 2>particular Because to be clear, we'll go ahead and get

0:02:20.400 --> 0:02:22.600
<v Speaker 2>into a little bit about it. We're talking about a

0:02:22.639 --> 0:02:27.800
<v Speaker 2>cactus that grows in the Sonoran Desert, and it's it's

0:02:27.880 --> 0:02:31.560
<v Speaker 2>probably the most defining example of the flora there the

0:02:31.600 --> 0:02:34.160
<v Speaker 2>Sonoran Desert. To remind everyone, I think we discussed it

0:02:34.200 --> 0:02:38.480
<v Speaker 2>briefly in one of our previous desert episodes, the Carshner

0:02:38.520 --> 0:02:42.959
<v Speaker 2>Caverns episode. Actually, actually this is a desert that dips

0:02:42.960 --> 0:02:45.080
<v Speaker 2>more or less straight down from the southern limits of

0:02:45.120 --> 0:02:50.359
<v Speaker 2>the higher elevation Mojave Great Basin and Colorado Plateau Deserts

0:02:50.720 --> 0:02:54.560
<v Speaker 2>and dives down around the Gulf of California on both sides. So,

0:02:54.880 --> 0:02:58.359
<v Speaker 2>all told, the desert ecosystem here covers parts of the

0:02:58.400 --> 0:03:04.160
<v Speaker 2>northwestern Mexican state of Sonora, Baja California, Baja California, sir

0:03:04.600 --> 0:03:07.440
<v Speaker 2>and then also parts of the southwestern US states of

0:03:07.480 --> 0:03:09.240
<v Speaker 2>Arizona and California.

0:03:09.360 --> 0:03:14.720
<v Speaker 3>Yeah. So, actually, the geographic range of the Souarro cactus

0:03:15.360 --> 0:03:19.280
<v Speaker 3>is more limited than you might guess based on the

0:03:19.320 --> 0:03:22.760
<v Speaker 3>way it's used in say, movies and TV shows, where

0:03:23.160 --> 0:03:27.520
<v Speaker 3>if you watch westerns, you know, Western shows set in

0:03:27.560 --> 0:03:31.760
<v Speaker 3>the American West, you could be forgiven for thinking that

0:03:31.840 --> 0:03:35.440
<v Speaker 3>the suaro is basically everywhere west of the Mississippi. I mean,

0:03:35.440 --> 0:03:38.520
<v Speaker 3>it's just like it's in all of the Westerns, whether

0:03:38.560 --> 0:03:42.680
<v Speaker 3>they're said in Texas or Wyoming or Nevada or you know, wherever.

0:03:42.760 --> 0:03:46.080
<v Speaker 3>It's just like, Okay, we're somewhere. It's it's somewhere dry.

0:03:46.240 --> 0:03:49.080
<v Speaker 3>We're somewhere out to the west, and we've got this cactus.

0:03:49.080 --> 0:03:51.720
<v Speaker 3>The arms are pointing up, and that's how you know

0:03:51.760 --> 0:03:52.280
<v Speaker 3>where we are.

0:03:52.600 --> 0:03:54.920
<v Speaker 2>Yeah, and where in reality, it's not even all of

0:03:54.960 --> 0:03:59.640
<v Speaker 2>the Sonoran Desert. Really only slight extensions of the range

0:03:59.680 --> 0:04:02.560
<v Speaker 2>goes in California. Nothing on the Baja Peninsula, I believe,

0:04:02.800 --> 0:04:07.320
<v Speaker 2>mostly concentrated in a slice of territory that extends from

0:04:07.720 --> 0:04:15.160
<v Speaker 2>somewhat northwest of Phoenix in South just south below Guimus

0:04:15.200 --> 0:04:18.560
<v Speaker 2>in Mexico. So again, not even the whole Sonoran Desert,

0:04:19.200 --> 0:04:22.400
<v Speaker 2>but a sizable amount. But yeah, if you're watching Westerns,

0:04:22.400 --> 0:04:25.040
<v Speaker 2>and if you're watching old cartoons set and not even

0:04:25.040 --> 0:04:27.440
<v Speaker 2>old cartoons like in cartoons in general, or playing video

0:04:27.480 --> 0:04:31.839
<v Speaker 2>games that have a setting with the desert, you're gonna

0:04:32.040 --> 0:04:37.000
<v Speaker 2>you're gonna probably see depictions of the Suaro everywhere, even

0:04:37.400 --> 0:04:39.800
<v Speaker 2>in video like in Super Mario games in front of

0:04:39.839 --> 0:04:43.560
<v Speaker 2>the pyramids presumably of Egypt, though I guess it's some

0:04:43.600 --> 0:04:46.680
<v Speaker 2>sort of Super Mario world. But yeah, it would make

0:04:46.720 --> 0:04:48.640
<v Speaker 2>you think, oh, well, these things are just everywhere. But no,

0:04:48.720 --> 0:04:53.599
<v Speaker 2>it's even just a slim part of North America where

0:04:53.600 --> 0:04:54.240
<v Speaker 2>you'll find it.

0:04:54.440 --> 0:04:56.760
<v Speaker 3>I've actually got a note about suarrow in video games

0:04:56.760 --> 0:04:58.599
<v Speaker 3>to get to in a few minutes. Oh, I'm excited,

0:04:58.920 --> 0:04:59.440
<v Speaker 3>we'll get there.

0:05:00.000 --> 0:05:03.080
<v Speaker 2>Oh yeah, again, this is like the poster child of

0:05:03.920 --> 0:05:07.359
<v Speaker 2>you know, realistically of Sonoran desert cacti, but then also

0:05:07.520 --> 0:05:12.120
<v Speaker 2>just the most icon iconic cactus period. You know, I

0:05:12.240 --> 0:05:15.800
<v Speaker 2>was I was in a yoga class earlier today, and

0:05:16.600 --> 0:05:19.280
<v Speaker 2>we're always doing a pose with our arms called cactus pose.

0:05:19.480 --> 0:05:21.080
<v Speaker 2>This is where your arms go up like this. I

0:05:21.120 --> 0:05:23.480
<v Speaker 2>guess it's kind of like a Some might say it's

0:05:23.480 --> 0:05:25.640
<v Speaker 2>more like a football goal sort of a scenario, but

0:05:26.120 --> 0:05:30.800
<v Speaker 2>generally refer to as cactus pose. And uh and I

0:05:30.839 --> 0:05:32.920
<v Speaker 2>didn't even think about it until today. You know, I've

0:05:32.920 --> 0:05:36.200
<v Speaker 2>been reading about about the Sorrow all week, and I'm like, oh, yeah,

0:05:36.279 --> 0:05:39.279
<v Speaker 2>it's a soorrow post basically, like that is what that is?

0:05:39.320 --> 0:05:41.960
<v Speaker 2>How iconic this particular species of cactus is.

0:05:42.279 --> 0:05:44.800
<v Speaker 3>Right, because cactus pose, you could just be a column,

0:05:44.880 --> 0:05:47.279
<v Speaker 3>so it's great, or it could be like you do

0:05:47.320 --> 0:05:50.279
<v Speaker 3>a kind of twister tangle thing because you're a prickly

0:05:50.320 --> 0:05:51.200
<v Speaker 3>pear or something.

0:05:51.320 --> 0:05:53.560
<v Speaker 2>Yeah, or you're like a ural cactus, like get down

0:05:53.600 --> 0:05:55.880
<v Speaker 2>and just make a ball. Yeah, it's like be more

0:05:55.920 --> 0:05:56.919
<v Speaker 2>specific yogis.

0:05:57.320 --> 0:05:59.000
<v Speaker 3>Yeah, it's like saying animal pose.

0:06:00.120 --> 0:06:05.680
<v Speaker 2>Yeahs. But this also brings up another thing about the

0:06:05.680 --> 0:06:09.720
<v Speaker 2>suaro that's so iconic is that it lends itself very

0:06:09.760 --> 0:06:15.560
<v Speaker 2>easily to our anthropomorphizing it. You know, because they're tall,

0:06:16.160 --> 0:06:19.200
<v Speaker 2>they have a like, I don't want to overstate it,

0:06:19.279 --> 0:06:22.520
<v Speaker 2>like it's not like these things universally look like people,

0:06:22.680 --> 0:06:25.760
<v Speaker 2>and they are, you know, and they're often taller than people.

0:06:26.120 --> 0:06:30.400
<v Speaker 2>They don't always have the two arms, but they're close enough.

0:06:30.480 --> 0:06:32.479
<v Speaker 2>And granted, you know, things don't have to be very

0:06:32.480 --> 0:06:35.960
<v Speaker 2>close for them for us to answerpromorphize them. But yeah,

0:06:36.440 --> 0:06:38.280
<v Speaker 2>we see them and we think of some sort of

0:06:38.279 --> 0:06:42.039
<v Speaker 2>a towering human form, sometimes with limbs reaching towards the sky.

0:06:42.920 --> 0:06:46.600
<v Speaker 3>I remember drawing this cacti all the time when I

0:06:46.640 --> 0:06:50.760
<v Speaker 3>was a kid. I think in part because I liked

0:06:50.839 --> 0:06:55.279
<v Speaker 3>drawing desert scenes and they were sort of characteristic flora

0:06:55.360 --> 0:06:58.080
<v Speaker 3>of the desert. I you know, I wasn't making geographic

0:06:58.160 --> 0:07:00.000
<v Speaker 3>distinctions so I'm sure if I was trying to draw

0:07:00.120 --> 0:07:04.520
<v Speaker 3>the pyramids, I would draw it, you know, suaro cactus.

0:07:05.920 --> 0:07:08.360
<v Speaker 3>But also because of what you're talking about, because they

0:07:08.360 --> 0:07:12.040
<v Speaker 3>have that anthropomorphic quality, you could put sunglasses and a

0:07:12.080 --> 0:07:16.040
<v Speaker 3>hat on them, and I certainly did, but I would

0:07:16.080 --> 0:07:20.240
<v Speaker 3>go a step beyond and say, actually, they're not just anthropomorphic,

0:07:20.760 --> 0:07:25.680
<v Speaker 3>they're friendly. They're a certain type of anthropomorphic because of

0:07:25.720 --> 0:07:28.360
<v Speaker 3>the posture of the arms. Now, as you say correctly,

0:07:28.480 --> 0:07:31.280
<v Speaker 3>it's not just that they always have a central column

0:07:31.280 --> 0:07:34.240
<v Speaker 3>in two arms, but sometimes in nature they do. Sometimes

0:07:34.240 --> 0:07:36.800
<v Speaker 3>they got weirder arrangements, but you really do see that

0:07:37.280 --> 0:07:40.800
<v Speaker 3>two arm human arrangement out there in the world sometimes,

0:07:41.320 --> 0:07:45.880
<v Speaker 3>and because of the posture of the arms, they appear

0:07:45.960 --> 0:07:49.120
<v Speaker 3>to be either saying hello with one arm raised above

0:07:49.120 --> 0:07:52.320
<v Speaker 3>the other, or cheering with both arms raised, or maybe

0:07:52.360 --> 0:07:54.080
<v Speaker 3>doing the you know, the field goal like you were

0:07:54.120 --> 0:07:55.360
<v Speaker 3>saying the football field goal.

0:07:55.880 --> 0:07:59.520
<v Speaker 2>I guess it's also cornholio arms, right, that's right, Beavis, Yeah,

0:07:59.560 --> 0:08:02.920
<v Speaker 2>I need to But yeah, either way, it is a

0:08:03.000 --> 0:08:04.520
<v Speaker 2>positive kind of posture.

0:08:04.560 --> 0:08:08.400
<v Speaker 3>It suggests a friendliness. Whether you're saying hello or cheering,

0:08:08.480 --> 0:08:12.440
<v Speaker 3>that's a that's positive emotion in the posture. So I

0:08:12.480 --> 0:08:14.520
<v Speaker 3>don't know. It's it's not the only thing in nature

0:08:14.560 --> 0:08:17.280
<v Speaker 3>that looks like a human standing up, but it's kind

0:08:17.280 --> 0:08:19.800
<v Speaker 3>of cheery in the way that it resembles a human.

0:08:20.480 --> 0:08:22.320
<v Speaker 2>Yeah, and I mean there are a number of things

0:08:22.320 --> 0:08:26.360
<v Speaker 2>also playing into this. For the vast majority of cases,

0:08:26.400 --> 0:08:29.640
<v Speaker 2>they are not harmful to people. You know they are.

0:08:29.840 --> 0:08:32.959
<v Speaker 2>There is a gentle giant sense to them. And they

0:08:33.000 --> 0:08:38.439
<v Speaker 2>are pretty much the tallest natural organisms within their ecosystem,

0:08:38.480 --> 0:08:41.320
<v Speaker 2>and so they really stand out, you know, they are.

0:08:41.480 --> 0:08:45.000
<v Speaker 2>They are the giants of their ecosystem, of the snorin desert.

0:08:45.720 --> 0:08:48.000
<v Speaker 3>I wanted a minute ago, you were talking about their

0:08:48.120 --> 0:08:51.920
<v Speaker 3>use as as like sprites or decoration in video games,

0:08:52.000 --> 0:08:55.400
<v Speaker 3>sometimes just in the background. But I was remembering this also,

0:08:55.520 --> 0:08:58.679
<v Speaker 3>not think you mentioned Super Mario World. I don't particularly

0:08:58.720 --> 0:09:01.600
<v Speaker 3>remember that, But I have a more obscure video game memory,

0:09:02.120 --> 0:09:05.520
<v Speaker 3>which is of a game called Bunks Adventure for the

0:09:05.600 --> 0:09:08.800
<v Speaker 3>Turbographics sixteen. I was playing a little off the beaten path,

0:09:08.880 --> 0:09:11.679
<v Speaker 3>and I was a kid. There were some This is

0:09:11.679 --> 0:09:14.360
<v Speaker 3>a game where you play as sounds weird to describe.

0:09:14.360 --> 0:09:18.600
<v Speaker 3>I think you are a baby caveman who fights little

0:09:18.640 --> 0:09:23.480
<v Speaker 3>dinosaurs and you know, infected mammals and stuff by headbutting it.

0:09:23.559 --> 0:09:25.959
<v Speaker 3>Your head is your weapons, so you head butt things

0:09:26.840 --> 0:09:29.120
<v Speaker 3>and you can, you know, so you run around these

0:09:29.160 --> 0:09:32.240
<v Speaker 3>prehistoric landscapes full of dinosaurs. You know, let's put aside

0:09:32.240 --> 0:09:34.760
<v Speaker 3>the well actually of you know, dinosaurs and humans living

0:09:34.800 --> 0:09:38.200
<v Speaker 3>at the same time. But you're battling dinosaurs by headbutting them.

0:09:38.280 --> 0:09:40.880
<v Speaker 3>And one of the levels takes place in the desert,

0:09:41.120 --> 0:09:44.280
<v Speaker 3>and there are indeed these cactus enemies and they're clearly

0:09:44.320 --> 0:09:47.839
<v Speaker 3>siguaro modeled because they they've got arms like this, or

0:09:47.920 --> 0:09:50.280
<v Speaker 3>sometimes they flip the arms one up and one down,

0:09:51.000 --> 0:09:53.280
<v Speaker 3>but you know they're they're doing the bent arms like that,

0:09:53.440 --> 0:09:55.400
<v Speaker 3>and they've got the central column. And they also have

0:09:55.679 --> 0:09:59.080
<v Speaker 3>zany faces with yellow eyes going like whoa, whoa, whoa,

0:09:59.280 --> 0:10:01.920
<v Speaker 3>and you know, going oh with their mouth. They're kind

0:10:01.920 --> 0:10:04.760
<v Speaker 3>of doing the they're kind of doing the YouTube thumbnail

0:10:04.840 --> 0:10:09.480
<v Speaker 3>face or it's like wow, uh and uh. I think

0:10:09.520 --> 0:10:11.440
<v Speaker 3>if you jumped on them they would they would poke you.

0:10:11.559 --> 0:10:14.440
<v Speaker 3>So that's what But this burned in my memory as

0:10:14.440 --> 0:10:16.960
<v Speaker 3>a child. I'm sure when I was drawing cacti, I

0:10:17.000 --> 0:10:18.120
<v Speaker 3>was drawing those things.

0:10:19.240 --> 0:10:21.920
<v Speaker 2>Now they're not wearing sunglasses, but there does appear to

0:10:21.960 --> 0:10:25.360
<v Speaker 2>be a deret actyl that is wearing sunglasses here? Is

0:10:25.400 --> 0:10:25.800
<v Speaker 2>that true?

0:10:26.120 --> 0:10:28.680
<v Speaker 3>Yeah, that's right, Okay, I don't remember. I think that's

0:10:28.720 --> 0:10:31.679
<v Speaker 3>just another thing to headbutt. Yeah, when when all you've

0:10:31.679 --> 0:10:34.000
<v Speaker 3>got is ahead, the world looks like a nail.

0:10:35.720 --> 0:10:37.840
<v Speaker 2>All right, So let's come back to this name. That

0:10:38.000 --> 0:10:41.520
<v Speaker 2>is a scientific name for the war the suaro cactus

0:10:41.880 --> 0:10:47.640
<v Speaker 2>Carnegia gigantia. All right, So gigantia makes sense, you know, giant.

0:10:47.960 --> 0:10:50.400
<v Speaker 2>Clearly this is a big cactus. But where do we

0:10:50.440 --> 0:10:54.760
<v Speaker 2>get carnegia? Uh, some of you might be wondering, Hey,

0:10:55.440 --> 0:10:59.120
<v Speaker 2>is this cactus by any chance named after Andrew Carnegie?

0:10:59.520 --> 0:11:02.200
<v Speaker 2>The sky is bored American steel industrialist of the late

0:11:02.200 --> 0:11:04.200
<v Speaker 2>Gilded Age and early Progressive Age.

0:11:04.679 --> 0:11:05.680
<v Speaker 3>That's what I was wondering.

0:11:05.800 --> 0:11:09.560
<v Speaker 2>Yes, and it is absolutely the case. It is absolutely

0:11:09.640 --> 0:11:11.120
<v Speaker 2>named after him.

0:11:11.240 --> 0:11:12.840
<v Speaker 3>And did he invent this cactus?

0:11:12.960 --> 0:11:16.280
<v Speaker 2>No? No, But the story is actually really interesting and

0:11:16.360 --> 0:11:18.280
<v Speaker 2>ended up sort of getting like two versions of the

0:11:18.320 --> 0:11:22.120
<v Speaker 2>story of the same story here. So initially I was

0:11:22.160 --> 0:11:27.120
<v Speaker 2>looking at this was an article by the New York

0:11:27.160 --> 0:11:31.080
<v Speaker 2>Botanical Garden. It's titled This is from twenty twenty, titled

0:11:31.120 --> 0:11:35.400
<v Speaker 2>the Suaro Cactus emblematic plant of the American West and

0:11:35.440 --> 0:11:38.839
<v Speaker 2>the New York Botanical Garden. This was by Barbara M.

0:11:39.800 --> 0:11:44.160
<v Speaker 2>Years and this is just a little history, you know,

0:11:44.280 --> 0:11:49.000
<v Speaker 2>brief history of the cactus and its Western classification. And

0:11:49.200 --> 0:11:51.720
<v Speaker 2>so I'm gonna I'm gonna roll through some of this here.

0:11:52.200 --> 0:11:57.439
<v Speaker 2>So the cactus is described in the West, apparently first

0:11:57.440 --> 0:12:01.840
<v Speaker 2>by US Mexico Boundary survey bytanist and explorer Charles Perry

0:12:02.160 --> 0:12:05.760
<v Speaker 2>between eighteen forty eight and eighteen fifty three, though he

0:12:05.800 --> 0:12:08.400
<v Speaker 2>did not bring a specimen back with him, but he

0:12:08.440 --> 0:12:12.720
<v Speaker 2>brings back word and writings about them. Okay, Then Cacti

0:12:12.880 --> 0:12:17.480
<v Speaker 2>botanist George Engelman expands on Perry's work and names the

0:12:17.559 --> 0:12:24.360
<v Speaker 2>new cactus serious gigantius. And I want to reference here

0:12:24.400 --> 0:12:28.520
<v Speaker 2>that there's another My main book that I turned to

0:12:28.559 --> 0:12:32.120
<v Speaker 2>research for this episode is The Soarro Cactus, a Natural

0:12:32.200 --> 0:12:35.319
<v Speaker 2>History from the University of Arizona Press by David Yetman,

0:12:35.760 --> 0:12:42.240
<v Speaker 2>Alberto Broquz, Kevin Holteen, and Michael Sanderson. An excellent book

0:12:42.240 --> 0:12:45.040
<v Speaker 2>that I highly recommend. And so I'm also going to

0:12:45.120 --> 0:12:48.160
<v Speaker 2>have some additional thoughts from them. But they include in

0:12:48.280 --> 0:12:51.920
<v Speaker 2>their book one of the images that Englman created of

0:12:51.960 --> 0:12:55.440
<v Speaker 2>this specimen of cactus, and it is it is pretty

0:12:55.440 --> 0:13:00.400
<v Speaker 2>amazing because the scale of the suaro is bonkers. They're

0:13:00.400 --> 0:13:04.720
<v Speaker 2>depicting a cactus significantly larger and taller than any known specimen,

0:13:05.120 --> 0:13:07.560
<v Speaker 2>and the authors of the book point out that the

0:13:07.559 --> 0:13:09.640
<v Speaker 2>picture is also quote a tad romantic.

0:13:10.320 --> 0:13:14.400
<v Speaker 3>It's funny because from this illustration, I do get the

0:13:14.440 --> 0:13:16.840
<v Speaker 3>real sense of it. Like if you've never seen a

0:13:16.880 --> 0:13:19.040
<v Speaker 3>suarro before and you'd only seen this picture and then

0:13:19.080 --> 0:13:21.840
<v Speaker 3>you came across one, you could probably recognize it. You

0:13:21.880 --> 0:13:23.559
<v Speaker 3>may like, oh, that's what I saw on the picture

0:13:23.600 --> 0:13:26.440
<v Speaker 3>in this book. At the same time, yeah, it does

0:13:26.480 --> 0:13:30.439
<v Speaker 3>seem a little oh, it feels a little beyond real.

0:13:30.600 --> 0:13:33.320
<v Speaker 3>It feels a little fantasy, like an illustration from an

0:13:33.360 --> 0:13:37.120
<v Speaker 3>alien planet. And it's got I don't know, something about

0:13:37.160 --> 0:13:39.880
<v Speaker 3>the angles are a little too regular here, like it

0:13:39.920 --> 0:13:42.680
<v Speaker 3>actually has kind of right angles in all the arms

0:13:43.559 --> 0:13:46.440
<v Speaker 3>and the arrangement. Just feel something's a little off.

0:13:46.960 --> 0:13:51.000
<v Speaker 2>Yeah, yeah, I mean besides the size, Yeah, yeah, I

0:13:51.000 --> 0:13:53.920
<v Speaker 2>mean he is I think leaning into the majesty of

0:13:54.160 --> 0:13:57.360
<v Speaker 2>the suaro here and attempting to capture it and succeeding

0:13:57.400 --> 0:14:00.680
<v Speaker 2>in capturing that while also kind of fudging the scale

0:14:00.720 --> 0:14:04.360
<v Speaker 2>of everything, and to your point, like the desert seeming

0:14:04.440 --> 0:14:06.800
<v Speaker 2>like an alien world, I mean, it does, you know,

0:14:06.880 --> 0:14:09.559
<v Speaker 2>And then that is the impression it leaves on. One

0:14:10.679 --> 0:14:13.280
<v Speaker 2>I toured while I was in Arizona, toured a Frank

0:14:13.320 --> 0:14:16.600
<v Speaker 2>Loyd Wright's house out there, and one of the things

0:14:16.640 --> 0:14:20.560
<v Speaker 2>they said was that that right would describe the surrounding

0:14:20.640 --> 0:14:23.440
<v Speaker 2>desert landscape as being like the bottom of the ocean,

0:14:23.880 --> 0:14:25.720
<v Speaker 2>and then looking out on it, he felt like he

0:14:25.800 --> 0:14:28.360
<v Speaker 2>was at the bottom of the sea. And so, you know,

0:14:28.400 --> 0:14:31.520
<v Speaker 2>those kinds of observations I think are valid in common.

0:14:31.880 --> 0:14:34.240
<v Speaker 3>That's kind of funny because I was thinking of this

0:14:34.360 --> 0:14:37.600
<v Speaker 3>illustration of the Suarro as being like a human made

0:14:37.640 --> 0:14:40.040
<v Speaker 3>antenna of some sort. So if it's the bottom of

0:14:40.080 --> 0:14:42.640
<v Speaker 3>the ocean, it's kind of the eltannan antenna out there

0:14:42.640 --> 0:14:44.920
<v Speaker 3>in the desert, which in reality was not an antenna

0:14:44.960 --> 0:14:50.040
<v Speaker 3>but was a sponge absolutely you know, wildlife. So yeah,

0:14:50.120 --> 0:14:52.760
<v Speaker 3>that is interesting, though I feel like we want to

0:14:52.760 --> 0:14:55.360
<v Speaker 3>be careful at the same time that we don't sell

0:14:55.600 --> 0:14:59.480
<v Speaker 3>short how giant these things can get, Like this picture

0:14:59.560 --> 0:15:03.720
<v Speaker 3>might be bit exaggerated, but these things can in their maturity,

0:15:03.760 --> 0:15:06.640
<v Speaker 3>can become absolutely huge. They grow to like seventy feet

0:15:06.720 --> 0:15:07.200
<v Speaker 3>or something.

0:15:07.520 --> 0:15:10.360
<v Speaker 2>Yeah, yeah, a few numbers on that. So we're talking

0:15:10.400 --> 0:15:15.120
<v Speaker 2>occasional heights of twelve meters or forty feet, and fifteen

0:15:15.200 --> 0:15:17.960
<v Speaker 2>meters or fifty foot specimens are seen from time to time,

0:15:18.440 --> 0:15:21.360
<v Speaker 2>and then the record this, according to that University of

0:15:21.360 --> 0:15:25.480
<v Speaker 2>Arizona book, was a twenty three meter or seventy eight

0:15:25.560 --> 0:15:31.080
<v Speaker 2>foot sorrow found near Cave Creek, Arizona, that was sadly

0:15:31.120 --> 0:15:32.880
<v Speaker 2>toppled by winds in nineteen eighty six.

0:15:33.240 --> 0:15:37.720
<v Speaker 3>Okay, so above seventy feet is not impossible, but is exceptional.

0:15:37.800 --> 0:15:42.440
<v Speaker 3>But it would not be unusual to get mature cacti

0:15:42.720 --> 0:15:45.040
<v Speaker 3>of the species that are like fifty feet right.

0:15:45.080 --> 0:15:47.120
<v Speaker 2>The ones in this image, though, I'm thinking, are like

0:15:47.160 --> 0:15:50.920
<v Speaker 2>one hundred and twenty feet. Okay, yeah, if I'm sort

0:15:50.960 --> 0:15:54.960
<v Speaker 2>of like stacking my people correctly, because the image shows

0:15:55.000 --> 0:15:58.800
<v Speaker 2>some little humans in the foreground here. Yeah, all right,

0:15:58.880 --> 0:16:03.240
<v Speaker 2>So pictures of the cactus are making their way back

0:16:03.280 --> 0:16:07.280
<v Speaker 2>to New York, and this is the point where, according

0:16:07.320 --> 0:16:11.880
<v Speaker 2>to that New York Botanical Garden article, enters New York

0:16:11.880 --> 0:16:16.480
<v Speaker 2>Botanical Garden founder Nathaniel Britton and fellow botanist Joseph N.

0:16:16.600 --> 0:16:20.360
<v Speaker 2>Rose and they decide at some point in this that, Okay,

0:16:20.400 --> 0:16:24.040
<v Speaker 2>this cactus really needs its own genus, and they decide

0:16:24.040 --> 0:16:26.920
<v Speaker 2>to name it after Andrew Carnegie and write to him

0:16:26.920 --> 0:16:29.480
<v Speaker 2>in nineteen oh two to ask his permission to do so,

0:16:30.320 --> 0:16:36.200
<v Speaker 2>and that article of the New York Botanical Garden. I

0:16:36.280 --> 0:16:39.800
<v Speaker 2>do really love the response, I assume via telegram that

0:16:39.880 --> 0:16:43.480
<v Speaker 2>comes from Carnegie's secretary informing them that mister Carnegie quote

0:16:43.800 --> 0:16:45.840
<v Speaker 2>asked me to say that he is greatly honored by

0:16:45.840 --> 0:16:47.960
<v Speaker 2>the proposal and will do his best to live up

0:16:48.000 --> 0:16:49.680
<v Speaker 2>to it.

0:16:49.720 --> 0:16:52.920
<v Speaker 3>Can I be as grand as a cactus right now?

0:16:52.960 --> 0:16:55.160
<v Speaker 2>At this point, you may have a number of thoughts

0:16:55.200 --> 0:16:57.200
<v Speaker 2>about on this. You know, you might well find it

0:16:57.280 --> 0:17:00.800
<v Speaker 2>horrid to imagine that this long time din of the

0:17:00.800 --> 0:17:05.600
<v Speaker 2>desert that humans had known about for millennia should be

0:17:05.680 --> 0:17:09.640
<v Speaker 2>named after a New York City industrialist, robber baron, if

0:17:09.640 --> 0:17:12.159
<v Speaker 2>you will. And I'm not saying that that judgment is

0:17:12.200 --> 0:17:16.159
<v Speaker 2>completely invalid. But on the other hand, Carnegie became a

0:17:16.160 --> 0:17:20.680
<v Speaker 2>devoted philanthropist late in life, and funds from his fortune

0:17:20.720 --> 0:17:25.160
<v Speaker 2>helped establish for starters the Desert Botanical Laboratory, founded near Tucson,

0:17:25.200 --> 0:17:27.800
<v Speaker 2>and I believe nineteen oh three in addition to various

0:17:27.800 --> 0:17:33.719
<v Speaker 2>other philanthropic venturers championing things like world peace, education, scientific research. So,

0:17:33.920 --> 0:17:36.960
<v Speaker 2>in short, if you're looking at all the various monopoly

0:17:37.040 --> 0:17:41.159
<v Speaker 2>maned tycoons of the day, Andrew Carnegie is arguably not

0:17:41.280 --> 0:17:43.159
<v Speaker 2>the worst by any stretch of the imagination.

0:17:43.880 --> 0:17:47.400
<v Speaker 3>I haven't done enough reading comment confidently on that, but

0:17:47.640 --> 0:17:52.680
<v Speaker 3>it's true. My general impression is, yeah, that he's more

0:17:52.760 --> 0:17:55.800
<v Speaker 3>invested in philanthropy than some of the others of his time,

0:17:55.840 --> 0:17:57.680
<v Speaker 3>and certainly than some of our time.

0:17:57.880 --> 0:18:01.240
<v Speaker 2>Yeah. Yeah, But you still might say, well, does he

0:18:01.320 --> 0:18:04.200
<v Speaker 2>deserve to have a cactus named after him? Maybe not.

0:18:04.520 --> 0:18:07.600
<v Speaker 2>And the interesting thing is, I don't think even Carnegie

0:18:07.680 --> 0:18:10.080
<v Speaker 2>thought that a cactus should be named after him, Because

0:18:10.480 --> 0:18:12.600
<v Speaker 2>when I was well, when I finally got to the

0:18:12.640 --> 0:18:14.960
<v Speaker 2>part of the University of Arizona book that I referenced

0:18:15.000 --> 0:18:17.760
<v Speaker 2>earlier where they talk about the Carnegie situation, the way

0:18:17.840 --> 0:18:21.840
<v Speaker 2>they tell it is that the Desert Laboratory in Tucson, Yes,

0:18:21.840 --> 0:18:24.919
<v Speaker 2>acquired much of its early funding from Carnegie, and they

0:18:25.000 --> 0:18:28.040
<v Speaker 2>invited him out to visit the site, and during his visit,

0:18:28.200 --> 0:18:31.159
<v Speaker 2>they showed him some suarros and told him that the

0:18:31.160 --> 0:18:34.399
<v Speaker 2>plant had been named for him in like a blatant

0:18:34.400 --> 0:18:37.399
<v Speaker 2>attempt to flatter him, and he did not take it

0:18:37.440 --> 0:18:40.000
<v Speaker 2>well that he saw this as just naked pandering and

0:18:40.160 --> 0:18:43.679
<v Speaker 2>was like, you know, how, why are you renaming this

0:18:43.800 --> 0:18:47.200
<v Speaker 2>Like surely this species was already known to humans. It's

0:18:47.240 --> 0:18:50.919
<v Speaker 2>too you know, outrageous and obvious a specimen that you know.

0:18:51.160 --> 0:18:54.480
<v Speaker 2>He did not like this. He did continue to fund

0:18:54.480 --> 0:18:58.520
<v Speaker 2>the Desert the Desert Laboratory, however, and I'm assuming if

0:18:58.520 --> 0:19:00.560
<v Speaker 2>we're to sort of piece these two stories is together.

0:19:01.000 --> 0:19:04.080
<v Speaker 2>His secretary at least responds with a nice note later on,

0:19:04.240 --> 0:19:06.960
<v Speaker 2>but it sounds like in the moment he maybe did

0:19:07.000 --> 0:19:10.200
<v Speaker 2>not see this as is a great thing that the

0:19:10.240 --> 0:19:12.320
<v Speaker 2>skeptics was being named after him, and then did not

0:19:12.359 --> 0:19:14.479
<v Speaker 2>see why it was necessary and again saw it as

0:19:14.520 --> 0:19:15.680
<v Speaker 2>just naked pandering.

0:19:16.400 --> 0:19:19.159
<v Speaker 3>Well, I can appreciate not wanting to be pandered to

0:19:19.280 --> 0:19:21.240
<v Speaker 3>in that way, And in my case, if somebody tried

0:19:21.240 --> 0:19:22.920
<v Speaker 3>to name a species after me, I think I would

0:19:22.920 --> 0:19:23.639
<v Speaker 3>be embarrassed.

0:19:24.200 --> 0:19:26.360
<v Speaker 2>You heard it here, folks. If you're out there listening

0:19:26.840 --> 0:19:29.880
<v Speaker 2>and you're thinking about naming a species after Joe McCormick,

0:19:29.960 --> 0:19:31.040
<v Speaker 2>do not do it.

0:19:31.400 --> 0:19:34.920
<v Speaker 3>That's going to happen. You never know I mean, I'm

0:19:34.960 --> 0:19:37.920
<v Speaker 3>not gonna be mad, but I'm not asking for that.

0:19:38.000 --> 0:19:39.280
<v Speaker 2>What have you discovered though?

0:19:40.440 --> 0:19:43.880
<v Speaker 3>I don't know I'd find that unlikely, but who knows.

0:19:44.320 --> 0:19:46.879
<v Speaker 3>Where were we though? But oh wait, so but doesn't

0:19:46.920 --> 0:19:49.679
<v Speaker 3>it retain the Carnegie name? So it is an issue

0:19:49.720 --> 0:19:51.880
<v Speaker 3>like he didn't love this, but they was like, well,

0:19:51.920 --> 0:19:53.600
<v Speaker 3>we already had the place cards printed out.

0:19:53.760 --> 0:19:59.359
<v Speaker 2>Yeah, it's stuck like that is still the Suaro's scientific classification.

0:19:59.480 --> 0:20:01.679
<v Speaker 2>You can anywhere you read about it. So I had

0:20:01.680 --> 0:20:03.440
<v Speaker 2>read about it in the past, clearly when I'd gone

0:20:03.480 --> 0:20:06.639
<v Speaker 2>to various like desert botanical gardens and so forth, but

0:20:07.640 --> 0:20:10.480
<v Speaker 2>I hadn't really noticed it and questioned the name until

0:20:10.720 --> 0:20:11.400
<v Speaker 2>this research.

0:20:12.280 --> 0:20:15.600
<v Speaker 3>Yeah, I mean, yeah, maybe it blends enough in with

0:20:15.640 --> 0:20:21.119
<v Speaker 3>some other biological sounding words like carnegiea carnotaurus kind of

0:20:21.240 --> 0:20:26.240
<v Speaker 3>or is it like carnos something sounds like meat or flesh.

0:20:26.480 --> 0:20:28.240
<v Speaker 2>I don't know, yeah, Or it's one of those things

0:20:28.240 --> 0:20:30.600
<v Speaker 2>where at first I was like is it named after Carnegie?

0:20:30.640 --> 0:20:32.439
<v Speaker 2>And then like, well, maybe it's not named after the

0:20:32.520 --> 0:20:35.520
<v Speaker 2>most obvious Carnegie out there. I'm just jumped to conclusions.

0:20:35.520 --> 0:20:47.919
<v Speaker 2>But no, the conclusion would be correct, all right, So

0:20:48.160 --> 0:20:52.160
<v Speaker 2>we already talked about just how tall this particular cactus

0:20:52.200 --> 0:20:56.560
<v Speaker 2>can get. It is indeed a desert giant, the tallest

0:20:56.600 --> 0:20:59.760
<v Speaker 2>and largest cactus in the United States, and the tallest

0:20:59.800 --> 0:21:02.480
<v Speaker 2>deser planned in the US as well. If you dip

0:21:02.560 --> 0:21:07.000
<v Speaker 2>down into the territory of Mexico proper, there is a

0:21:07.119 --> 0:21:12.960
<v Speaker 2>variety of related cactus called the Mexican giant cardone or

0:21:13.040 --> 0:21:18.240
<v Speaker 2>the elephant cactus, and that one can grow larger. Though.

0:21:18.840 --> 0:21:21.320
<v Speaker 2>This is one of those things where it's like, what

0:21:21.440 --> 0:21:23.919
<v Speaker 2>is the tallest cactus now versus what is the tallest

0:21:23.920 --> 0:21:26.119
<v Speaker 2>cactus ever? You can kind of go back and forth

0:21:26.160 --> 0:21:31.480
<v Speaker 2>on that. But the authors of the University of Arizona

0:21:31.520 --> 0:21:37.760
<v Speaker 2>book note that the exceptional specimen from Cave Creek, Arizona,

0:21:37.800 --> 0:21:40.480
<v Speaker 2>the one that was like seventy eight feet tall, This

0:21:40.520 --> 0:21:44.360
<v Speaker 2>would have dwarfed the oldest known living cactus species today.

0:21:44.440 --> 0:21:49.000
<v Speaker 2>Presumably they're referring to an elephant cactus. Yeah, but still,

0:21:49.040 --> 0:21:52.879
<v Speaker 2>anyway you slice it, really tall cactus. They're the tallest

0:21:52.880 --> 0:21:56.120
<v Speaker 2>plants in there in their ecosystem, and yeah, they really

0:21:56.160 --> 0:21:58.760
<v Speaker 2>stand out. They define their part of the Sonoran Desert.

0:21:59.280 --> 0:22:01.720
<v Speaker 2>And I remember being really struck by them the first

0:22:01.720 --> 0:22:04.399
<v Speaker 2>time that I visited Arizona because when you leave the

0:22:04.440 --> 0:22:08.359
<v Speaker 2>airport in Phoenix, they're basically there. Like, they don't just

0:22:08.400 --> 0:22:11.040
<v Speaker 2>dot the landscape outside of the city. You will find

0:22:11.040 --> 0:22:13.159
<v Speaker 2>them throughout the Phoenix metropolitan area.

0:22:13.960 --> 0:22:19.400
<v Speaker 3>Yeah, speaking to their size and interactions with humans, maybe

0:22:19.400 --> 0:22:21.400
<v Speaker 3>this is a good place to mention. You know, there

0:22:21.520 --> 0:22:27.600
<v Speaker 3>is at least one famous souaro cactus related death which

0:22:27.840 --> 0:22:31.160
<v Speaker 3>I was reading about. I got there actually by way

0:22:31.160 --> 0:22:35.119
<v Speaker 3>of a song. So there is a song by so

0:22:35.200 --> 0:22:37.080
<v Speaker 3>I've read somewhere about the song. I went and listened

0:22:37.080 --> 0:22:39.560
<v Speaker 3>to the song. It's by a Texas band called the

0:22:39.600 --> 0:22:44.920
<v Speaker 3>Austin Lounge Lizards, and it is a Western style ballad

0:22:45.400 --> 0:22:49.320
<v Speaker 3>that I think is somewhat satirical because it is talking

0:22:49.320 --> 0:22:51.760
<v Speaker 3>about this character sort of going out and suiting up

0:22:51.800 --> 0:22:56.200
<v Speaker 3>for battle against a cactus. And so it's telling the

0:22:56.359 --> 0:22:59.560
<v Speaker 3>true to life story of a guy named David Grundman

0:23:00.040 --> 0:23:04.040
<v Speaker 3>who was crushed by a falling souarro after he shot

0:23:04.080 --> 0:23:07.400
<v Speaker 3>it in. I guess it was the year nineteen eighty one,

0:23:07.640 --> 0:23:11.600
<v Speaker 3>I think, because I was looking for a little more

0:23:11.640 --> 0:23:13.399
<v Speaker 3>on this and I found a New York Times article

0:23:13.440 --> 0:23:17.280
<v Speaker 3>from nineteen eighty two which says, quote last February twenty seven,

0:23:17.359 --> 0:23:20.240
<v Speaker 3>year old David M. Grundman took to the desert near

0:23:20.280 --> 0:23:23.960
<v Speaker 3>here with a shotgun and two rifles and began blasting

0:23:24.000 --> 0:23:27.760
<v Speaker 3>away at a twenty three foot tall Souarro cactus. The cactus,

0:23:27.800 --> 0:23:31.840
<v Speaker 3>mortally wounded by the gunfire, suddenly toppled over on mister Grundman,

0:23:32.240 --> 0:23:36.520
<v Speaker 3>crushing him to death. From that, it does kind of

0:23:36.520 --> 0:23:39.159
<v Speaker 3>sound like the whole thing fell over from the trunk,

0:23:39.240 --> 0:23:42.720
<v Speaker 3>But based on other summaries of the story I was reading,

0:23:42.760 --> 0:23:44.920
<v Speaker 3>it sounds more like one of the arms fell off

0:23:44.960 --> 0:23:48.040
<v Speaker 3>and like it fell onto his car and killed him.

0:23:48.600 --> 0:23:51.520
<v Speaker 3>So I'm not sure exactly which version of the story

0:23:51.560 --> 0:23:53.879
<v Speaker 3>is correct there, but yet it is verified that it

0:23:54.280 --> 0:23:57.000
<v Speaker 3>in some way this guy was killed by shooting at

0:23:57.000 --> 0:23:58.560
<v Speaker 3>a cactus until it fell on him.

0:23:59.600 --> 0:24:02.760
<v Speaker 2>Well, you know, we do not take delight in human

0:24:02.800 --> 0:24:05.240
<v Speaker 2>death here on stuff will blow your mind. But yeah,

0:24:05.280 --> 0:24:10.440
<v Speaker 2>there is something about the story that maybe inspires morbid humor.

0:24:10.520 --> 0:24:12.199
<v Speaker 2>I don't know. Maybe it's the fact that it kind

0:24:12.240 --> 0:24:15.040
<v Speaker 2>of reminds one of Don Quixote going up against the

0:24:15.080 --> 0:24:18.840
<v Speaker 2>windmills or something, you know, And you know, it seems

0:24:18.880 --> 0:24:21.600
<v Speaker 2>like a on the whole very avoidable death as long

0:24:21.640 --> 0:24:23.159
<v Speaker 2>as you don't go out and start shooting at the

0:24:23.160 --> 0:24:26.080
<v Speaker 2>basis of cacti that are not asking for it.

0:24:25.880 --> 0:24:29.280
<v Speaker 3>It does raise questions, Yes, what did the cactus do

0:24:29.400 --> 0:24:32.240
<v Speaker 3>to provoke this? It doesn't seem like anything could have

0:24:32.520 --> 0:24:37.800
<v Speaker 3>could have been been justifiable. So yeah, so it seems

0:24:37.880 --> 0:24:40.879
<v Speaker 3>not advisable to go shooting at cactus, especially if you're

0:24:40.920 --> 0:24:43.240
<v Speaker 3>standing close to them. But yeah, not really at all.

0:24:43.320 --> 0:24:45.399
<v Speaker 3>I mean, why do you need to shoot a cactus?

0:24:45.680 --> 0:24:48.680
<v Speaker 2>Yeah, I think there's part of this situation too, might

0:24:48.720 --> 0:24:52.720
<v Speaker 2>be like a basic tendency to misunderstand not how big

0:24:52.720 --> 0:24:54.520
<v Speaker 2>they are, but also just how heavy they are.

0:24:54.840 --> 0:24:57.080
<v Speaker 3>Oh yeah, because you might assume they're they're kind of

0:24:57.240 --> 0:24:59.119
<v Speaker 3>like soft and light or something.

0:24:59.200 --> 0:25:01.960
<v Speaker 2>Yeah, or like a like an inflatable from a used

0:25:01.960 --> 0:25:05.959
<v Speaker 2>car dealership or something. But now these are stout. They

0:25:06.000 --> 0:25:09.439
<v Speaker 2>can get quite heavy. They're like eighty percent water. I

0:25:09.440 --> 0:25:11.240
<v Speaker 2>believe that's the percent. I will come back to it

0:25:11.280 --> 0:25:13.840
<v Speaker 2>here in a bit, but yeah, these are these are

0:25:13.880 --> 0:25:18.280
<v Speaker 2>these are hefty, hefty specimens. Now, before we talk more

0:25:18.320 --> 0:25:21.040
<v Speaker 2>about the sorrow, I wanted to talk a little bit

0:25:21.080 --> 0:25:27.439
<v Speaker 2>about cactuses in general, cactus origins and getting into why

0:25:27.680 --> 0:25:32.040
<v Speaker 2>the cactus unlike other succulents are native to the Americus.

0:25:32.520 --> 0:25:35.280
<v Speaker 2>So I'm not gonna spend a ton of time on this,

0:25:35.400 --> 0:25:37.720
<v Speaker 2>but basically, here's the here's the quick and dirty version.

0:25:38.280 --> 0:25:41.000
<v Speaker 2>So cactus origins in general date back to the mid

0:25:41.080 --> 0:25:44.400
<v Speaker 2>Tertiary period, so roughly twenty three to forty million years

0:25:44.400 --> 0:25:47.600
<v Speaker 2>ago we're talking about with this period, and it concerns

0:25:47.680 --> 0:25:49.760
<v Speaker 2>a period when we had like a great drying out

0:25:49.920 --> 0:25:53.240
<v Speaker 2>on a kind of harsh earth. This great drying out

0:25:53.320 --> 0:25:56.280
<v Speaker 2>allowed the evolution of various life forms that could survive

0:25:56.520 --> 0:26:01.920
<v Speaker 2>and or exploit dry, cooler temperatures and low rainfall. So

0:26:02.000 --> 0:26:05.439
<v Speaker 2>the authors of that University of Arizona book right that

0:26:05.520 --> 0:26:09.240
<v Speaker 2>this was a time during which the North American horses,

0:26:10.000 --> 0:26:13.520
<v Speaker 2>large South American birds, giant crocs, and prehistoric whales did

0:26:13.640 --> 0:26:17.400
<v Speaker 2>very well. And it's also when the oldest cactus species

0:26:17.440 --> 0:26:20.640
<v Speaker 2>seem to have diverged around thirty five million years ago

0:26:20.720 --> 0:26:24.119
<v Speaker 2>in South America, and this would have been long after

0:26:24.160 --> 0:26:29.080
<v Speaker 2>the split from Africa, thus the American isolation of the cactus.

0:26:29.440 --> 0:26:32.800
<v Speaker 2>So after these new this new type of plant life

0:26:32.800 --> 0:26:36.639
<v Speaker 2>gains a foothold, cactuses continue to spread and evolve and

0:26:36.640 --> 0:26:41.280
<v Speaker 2>fill new niches in response, to changing ecosystems, and eventually

0:26:41.320 --> 0:26:44.359
<v Speaker 2>we reach the point where today we have between something

0:26:44.440 --> 0:26:48.600
<v Speaker 2>like fourteen hundred and eighteen hundred and fifty cactus species

0:26:48.640 --> 0:26:51.800
<v Speaker 2>across one hundred and twenty five genera. You'll find cactus.

0:26:52.000 --> 0:26:54.840
<v Speaker 2>The numbers vary depending on who's doing accounting, but you'll

0:26:54.840 --> 0:26:58.600
<v Speaker 2>find cactuses as far north as into Canada. But in

0:26:58.680 --> 0:27:02.080
<v Speaker 2>general they grow small and fewer the farther north you

0:27:02.160 --> 0:27:05.080
<v Speaker 2>go after a certain point. And as we'll come back to,

0:27:05.160 --> 0:27:08.920
<v Speaker 2>part of this has to do with a cactus species

0:27:09.080 --> 0:27:13.520
<v Speaker 2>ability to survive freezes. But you know, cactuses come in

0:27:13.560 --> 0:27:16.800
<v Speaker 2>all forms. They fill various plant in inches, and they

0:27:16.880 --> 0:27:22.040
<v Speaker 2>range from very small and shrub like things to huge

0:27:22.080 --> 0:27:27.840
<v Speaker 2>treelike plants like the souarro. Again, these are the largest

0:27:27.960 --> 0:27:29.240
<v Speaker 2>of the tree like cacti.

0:27:30.000 --> 0:27:33.639
<v Speaker 3>Now, you mentioned that you know they have this sensitivity

0:27:33.720 --> 0:27:39.080
<v Speaker 3>to climate factors, and that's not only true for cacti

0:27:39.200 --> 0:27:42.760
<v Speaker 3>as a whole, but it is true even within a species.

0:27:42.880 --> 0:27:45.600
<v Speaker 3>So I don't know, I don't want to over undercut

0:27:45.600 --> 0:27:47.080
<v Speaker 3>you if you plan to talk about this later, but

0:27:47.359 --> 0:27:49.879
<v Speaker 3>one thing I was reading about was that you find

0:27:50.040 --> 0:27:54.600
<v Speaker 3>very different growth patterns for swaro itself depending on just

0:27:54.720 --> 0:27:56.560
<v Speaker 3>like what side of a mountain it's on.

0:27:56.880 --> 0:28:00.399
<v Speaker 2>Yeah, Like, for instance, I'm to understand the aerials space

0:28:00.480 --> 0:28:04.520
<v Speaker 2>different differently on on cacti than this suaros, depending on

0:28:04.560 --> 0:28:07.639
<v Speaker 2>where they're growing. These are the little the little like

0:28:07.760 --> 0:28:12.679
<v Speaker 2>nubs that the spines grow out of. Oh okay, yeah,

0:28:12.920 --> 0:28:17.560
<v Speaker 2>so yeah, speaking of spines, obviously cacti differ from plants

0:28:17.560 --> 0:28:20.960
<v Speaker 2>and that they have these spines. These like when you

0:28:21.040 --> 0:28:23.119
<v Speaker 2>draw a cactus as a child, what are you drawing

0:28:23.160 --> 0:28:25.960
<v Speaker 2>on there? You're drawing the little spines, Like that's probably

0:28:25.960 --> 0:28:26.600
<v Speaker 2>one of the most.

0:28:26.480 --> 0:28:27.240
<v Speaker 3>Love drawing those.

0:28:27.560 --> 0:28:27.800
<v Speaker 2>Fun.

0:28:28.960 --> 0:28:31.359
<v Speaker 3>I would I would draw a cactus with like a marker,

0:28:31.520 --> 0:28:33.320
<v Speaker 3>the green part with a marker and then get a

0:28:33.320 --> 0:28:35.760
<v Speaker 3>little mechanical pencil and do all the spines.

0:28:36.040 --> 0:28:36.360
<v Speaker 2>M hmm.

0:28:36.640 --> 0:28:38.120
<v Speaker 3>Yeah, yeah, that was fun.

0:28:38.520 --> 0:28:43.440
<v Speaker 2>Yeah, and yeah. These are evolutionarily derived from leaves, which

0:28:43.880 --> 0:28:47.400
<v Speaker 2>like new shoots, flowers, and fruits on a cactus, they

0:28:47.400 --> 0:28:50.720
<v Speaker 2>grow out of. These areoles, which the authors of the

0:28:50.800 --> 0:28:54.280
<v Speaker 2>University of Arizona book describe as felty lumps on the cactus.

0:28:54.920 --> 0:28:57.880
<v Speaker 2>And yeah, they're distributed in different ways in different species,

0:28:57.960 --> 0:29:00.560
<v Speaker 2>and even within a single species, things can laid out

0:29:00.560 --> 0:29:04.840
<v Speaker 2>a little bit differently. Except for a few primitive cactus species.

0:29:05.120 --> 0:29:08.960
<v Speaker 2>Cactuses generally lack leaves, though some species like the Prickly pair,

0:29:09.320 --> 0:29:14.000
<v Speaker 2>produce rudimentary leaves early in development. Leaves, though, are in

0:29:14.040 --> 0:29:16.640
<v Speaker 2>general too costly and too much of a water loss

0:29:16.680 --> 0:29:21.200
<v Speaker 2>for a cactus. There are also a few isolated cactus

0:29:21.200 --> 0:29:25.320
<v Speaker 2>species that lack spines. Now with the soarro, the spines

0:29:25.360 --> 0:29:28.360
<v Speaker 2>are white, up to five centimeters in length and space

0:29:28.440 --> 0:29:32.160
<v Speaker 2>generally around three centimeters apart. The spines, as it turns out,

0:29:32.640 --> 0:29:35.800
<v Speaker 2>produce rings as the plant grows and as it ages,

0:29:35.960 --> 0:29:41.520
<v Speaker 2>which botanists can then date. And why do cactuses in

0:29:41.560 --> 0:29:44.040
<v Speaker 2>general have spines? Well, well, I think we know the

0:29:44.040 --> 0:29:47.080
<v Speaker 2>most obvious reason, and that is to punish those that

0:29:47.120 --> 0:29:50.720
<v Speaker 2>would attempt to touch them, hug them, eat of them,

0:29:50.800 --> 0:29:54.800
<v Speaker 2>and so forth, to provide protection right mainly against herbivores.

0:29:55.320 --> 0:29:58.160
<v Speaker 2>But in addition to this, cactus spines boast various other

0:29:58.200 --> 0:30:00.720
<v Speaker 2>purposes that are pretty fascinating. But also it may not

0:30:00.800 --> 0:30:04.719
<v Speaker 2>seem as as obvious, you know, and of course all

0:30:04.720 --> 0:30:06.880
<v Speaker 2>these different things can work together at the same time.

0:30:06.960 --> 0:30:10.239
<v Speaker 2>But they can provide shade against sunburn for the for

0:30:10.320 --> 0:30:14.600
<v Speaker 2>these plants in their desert environments, they can trap heat

0:30:14.920 --> 0:30:20.160
<v Speaker 2>and help with freeze protection in colder climates. In some species,

0:30:20.480 --> 0:30:24.160
<v Speaker 2>spines may also help in moisture harvesting. Like you read

0:30:24.160 --> 0:30:27.200
<v Speaker 2>about these different cactuses that basically like drink the fog

0:30:27.840 --> 0:30:33.320
<v Speaker 2>and so forth. Cactus fruits also tend to be spiny

0:30:33.360 --> 0:30:36.080
<v Speaker 2>as well, protecting the fruits until they've reached the point

0:30:36.080 --> 0:30:37.960
<v Speaker 2>where they can ripen. At least, so there are a

0:30:38.000 --> 0:30:40.560
<v Speaker 2>number of different cactus fruits that as they ripen, the

0:30:40.640 --> 0:30:47.560
<v Speaker 2>spines kind of become less operational, so that the fruit

0:30:47.600 --> 0:30:49.640
<v Speaker 2>can then be eaten, the seeds can be spread, and

0:30:49.680 --> 0:30:52.320
<v Speaker 2>so forth. And though of course in this you get

0:30:52.320 --> 0:30:55.480
<v Speaker 2>into corresponding adaptations from all the organisms involved. You know,

0:30:55.520 --> 0:31:01.440
<v Speaker 2>some animals have spine management adaptations or techniques. Let's see,

0:31:01.640 --> 0:31:05.000
<v Speaker 2>on top of this, have cactus flowers in general, they

0:31:05.000 --> 0:31:07.760
<v Speaker 2>tend to be very colorful and stand out to attract pollinators.

0:31:08.080 --> 0:31:09.960
<v Speaker 2>I think we'll come back to some of that regarding

0:31:09.960 --> 0:31:12.640
<v Speaker 2>the souarro. And then also we should know that cacti

0:31:13.040 --> 0:31:17.320
<v Speaker 2>compensate for their lack of leaves by carrying out photosynthesis

0:31:17.360 --> 0:31:19.520
<v Speaker 2>through the skin and outer stems.

0:31:19.920 --> 0:31:23.480
<v Speaker 3>So this is why the stem itself of the cactus

0:31:23.560 --> 0:31:26.960
<v Speaker 3>is often green then that's because that's where the photosynthesis

0:31:27.040 --> 0:31:29.160
<v Speaker 3>is happening, is where the chlorophyll.

0:31:28.680 --> 0:31:31.200
<v Speaker 2>Needs to be right right, and also where the water

0:31:31.760 --> 0:31:34.960
<v Speaker 2>ends up being stored. So the authors of the University

0:31:35.000 --> 0:31:38.040
<v Speaker 2>of Arizona book point out that during the driest parts

0:31:38.040 --> 0:31:43.520
<v Speaker 2>of the year, the souaro's water it's excellent water conservation

0:31:43.760 --> 0:31:46.680
<v Speaker 2>is very obvious because they'll remain very green while upland

0:31:46.680 --> 0:31:50.600
<v Speaker 2>trees and shrubs basically become just brown and dried up

0:31:50.640 --> 0:31:52.880
<v Speaker 2>in appearance, even though they're still alive. They just they

0:31:53.040 --> 0:32:07.960
<v Speaker 2>basically look dead, but the cactus is still green now.

0:32:08.040 --> 0:32:12.120
<v Speaker 2>Souarros are columnar cacti, which means that their stem or

0:32:12.160 --> 0:32:16.640
<v Speaker 2>trunk and sometimes their limbs resemble columns. You know that

0:32:16.800 --> 0:32:20.440
<v Speaker 2>they're pretty, uh, pretty vertical in their structure for the

0:32:20.440 --> 0:32:23.320
<v Speaker 2>most part, not counting you know, in the arms and

0:32:23.400 --> 0:32:25.720
<v Speaker 2>so forth. But like a column, it is a strong,

0:32:25.880 --> 0:32:30.360
<v Speaker 2>stable structure. Uh. The sorrow in particular boasts the system

0:32:30.480 --> 0:32:35.400
<v Speaker 2>of ribs. These are rod like woody structures inside the

0:32:35.440 --> 0:32:41.080
<v Speaker 2>cactus that provides strength and durability and as a if

0:32:41.120 --> 0:32:45.720
<v Speaker 2>these cactus specimens are hurt or certainly after they die,

0:32:46.240 --> 0:32:49.880
<v Speaker 2>this this rib like structure remains and it begins to

0:32:49.880 --> 0:32:54.520
<v Speaker 2>create these very vivid, like spectacular scenes for the onlooker.

0:32:55.160 --> 0:32:58.080
<v Speaker 2>You will see examples of this, and it can take

0:32:58.120 --> 0:33:01.520
<v Speaker 2>on this, you know, almost kind of ghoulish appearance, because again,

0:33:01.560 --> 0:33:04.520
<v Speaker 2>already we look at these cac dyeing, we think about humans,

0:33:04.560 --> 0:33:06.640
<v Speaker 2>and we compare them to humans, and now we see

0:33:06.680 --> 0:33:08.840
<v Speaker 2>something that looks like bones inside of them.

0:33:09.120 --> 0:33:15.360
<v Speaker 3>Looks almost like a cross between bones and veins. Yeah yeah,

0:33:15.560 --> 0:33:18.800
<v Speaker 3>but it does have very much the appearance unlike other plants.

0:33:18.800 --> 0:33:21.959
<v Speaker 3>I can think of as the appearance of skin pulled

0:33:22.040 --> 0:33:25.560
<v Speaker 3>back from a human being and you're seeing the structures underneath.

0:33:26.040 --> 0:33:29.640
<v Speaker 2>Yeah yeah. Also reminds me very much of the monster

0:33:29.680 --> 0:33:31.760
<v Speaker 2>from I'm Married an alien from outer Space.

0:33:32.040 --> 0:33:34.320
<v Speaker 3>Oh yeah, yeah, yeah, a bit of that. But Robi,

0:33:34.640 --> 0:33:37.640
<v Speaker 3>particularly what I was just saying applies to one picture

0:33:37.640 --> 0:33:39.520
<v Speaker 3>I put in the outline for you to look at

0:33:39.960 --> 0:33:45.120
<v Speaker 3>of one where it's the outer covering that originally had

0:33:45.160 --> 0:33:48.160
<v Speaker 3>the spines and the green flesh is not completely gone,

0:33:48.840 --> 0:33:50.840
<v Speaker 3>but it is sort of peeling away, and so there's

0:33:50.840 --> 0:33:53.960
<v Speaker 3>a big window to look in at the underlying rib structure,

0:33:54.040 --> 0:33:56.560
<v Speaker 3>and it does look somewhat grotesque, and yeah, it looks

0:33:56.600 --> 0:34:01.400
<v Speaker 3>like it looks like one of those eighteenth cent illustrations

0:34:01.840 --> 0:34:04.640
<v Speaker 3>of like a you know, a dissection of a human

0:34:04.680 --> 0:34:07.480
<v Speaker 3>body and showing the layers underneath with the nerves and

0:34:07.520 --> 0:34:08.560
<v Speaker 3>the veins and everything.

0:34:09.160 --> 0:34:14.080
<v Speaker 2>Yeah. Absolutely, Now, columnar Cacti exists throughout the Americas, but

0:34:14.200 --> 0:34:18.600
<v Speaker 2>the the suaros survives far further north than any of

0:34:18.640 --> 0:34:22.839
<v Speaker 2>them due to its ability to survive mild freezes. And

0:34:22.880 --> 0:34:24.400
<v Speaker 2>apparently a lot of this has to do with just

0:34:24.440 --> 0:34:27.520
<v Speaker 2>the mass of the of of this particular plant, and

0:34:27.560 --> 0:34:29.759
<v Speaker 2>they can because they can survive a few hours of

0:34:29.800 --> 0:34:34.600
<v Speaker 2>below freezing temps like this, and on top of, on

0:34:34.640 --> 0:34:36.840
<v Speaker 2>top of just like the pure mass aspect of it,

0:34:37.400 --> 0:34:40.840
<v Speaker 2>it seems like there are environmental aspects of their range

0:34:40.960 --> 0:34:42.799
<v Speaker 2>in the sonor and that allows them to sort of

0:34:42.880 --> 0:34:45.840
<v Speaker 2>cheap by in colder months. So this has to do

0:34:45.880 --> 0:34:49.200
<v Speaker 2>with things like mountain shielding from certain wind patterns and

0:34:49.280 --> 0:34:51.920
<v Speaker 2>also passive heat storage and surrounding rocks.

0:34:52.239 --> 0:34:52.560
<v Speaker 3>Yeah.

0:34:52.760 --> 0:34:55.680
<v Speaker 2>Yeah, so I'm to understand it's kind of like the

0:34:55.680 --> 0:34:59.560
<v Speaker 2>gambit is, we may get freezing temperatures, but they will

0:34:59.560 --> 0:35:02.960
<v Speaker 2>not law quite long enough to kill the cactus and

0:35:03.480 --> 0:35:04.680
<v Speaker 2>specifically or.

0:35:04.719 --> 0:35:06.640
<v Speaker 3>To overcome our defenses against them.

0:35:06.760 --> 0:35:11.840
<v Speaker 2>Yeah, and we mentioned like differences in the sorrow depending

0:35:11.880 --> 0:35:15.160
<v Speaker 2>on where it's growing. I've read that most northern Solaro

0:35:15.239 --> 0:35:18.760
<v Speaker 2>specimens have spines to protect the ends of their frost

0:35:18.800 --> 0:35:22.720
<v Speaker 2>sensitive branches, so they'll be like extra spine growths there

0:35:22.800 --> 0:35:26.400
<v Speaker 2>that are just adding. It's like a little sweater that

0:35:26.440 --> 0:35:29.280
<v Speaker 2>they've made out of themselves for themselves, out of spines.

0:35:29.640 --> 0:35:34.160
<v Speaker 3>I was thinking, it's like putting covers on your outdoor

0:35:34.200 --> 0:35:36.120
<v Speaker 3>water faucets during the winter.

0:35:36.360 --> 0:35:40.360
<v Speaker 2>Yeah, yeah, yeah, except made out of spines. Now, I

0:35:40.360 --> 0:35:42.960
<v Speaker 2>want to come back to that book, the Soorrow Cactus.

0:35:43.320 --> 0:35:45.480
<v Speaker 2>I want to read a quick quote from it. They

0:35:45.480 --> 0:35:49.520
<v Speaker 2>write that quote, since soarros are about eighty percent water,

0:35:49.840 --> 0:35:53.160
<v Speaker 2>we can accurately view them as standing drums of water

0:35:53.239 --> 0:35:57.480
<v Speaker 2>that are effectively sealed from the outside. They point out

0:35:57.520 --> 0:36:01.360
<v Speaker 2>that the water inside the cactus is heavy. It's laden

0:36:01.560 --> 0:36:05.759
<v Speaker 2>or spiked with heavy isotopes of hydrogen and oxygen, and

0:36:06.080 --> 0:36:09.160
<v Speaker 2>this actually ends up marking the tissues of organisms that

0:36:09.239 --> 0:36:13.080
<v Speaker 2>consume bits of the cactus, such as you know, fruits

0:36:13.120 --> 0:36:16.000
<v Speaker 2>and nectar, in a way that has allowed scientists to

0:36:16.040 --> 0:36:20.480
<v Speaker 2>discover how much moisture various desert species gain from the

0:36:20.520 --> 0:36:21.880
<v Speaker 2>sooro in particular.

0:36:22.440 --> 0:36:25.200
<v Speaker 3>Oh okay, so by you take an animal and then

0:36:25.239 --> 0:36:28.960
<v Speaker 3>you look at the relative amount of deuterium or whatever

0:36:29.040 --> 0:36:31.440
<v Speaker 3>in it's in the water in its body, you can

0:36:31.480 --> 0:36:35.000
<v Speaker 3>tell if it's been getting into this cactus as opposed

0:36:35.000 --> 0:36:36.800
<v Speaker 3>to just rain water or something else.

0:36:37.120 --> 0:36:39.600
<v Speaker 2>Right, And I have I have not yet taken a

0:36:39.600 --> 0:36:41.879
<v Speaker 2>look at any of the specific studies that have done this,

0:36:42.080 --> 0:36:44.200
<v Speaker 2>but but it is. It is reference in the book here,

0:36:44.200 --> 0:36:46.000
<v Speaker 2>and I thought that was pretty fascinating. Like, you can

0:36:46.000 --> 0:36:49.040
<v Speaker 2>tell do they drink of the sooro? Do they depend

0:36:49.160 --> 0:36:52.880
<v Speaker 2>on it? There's like this, there's like this this water

0:36:52.960 --> 0:36:56.600
<v Speaker 2>tag in their body that lets you know that they do. Yeah, now,

0:36:56.640 --> 0:36:58.759
<v Speaker 2>speaking of that water, I think we may come back

0:36:58.800 --> 0:37:01.840
<v Speaker 2>to this in the next episode. But we need to

0:37:01.880 --> 0:37:05.600
<v Speaker 2>stress that whatever you have seen in a cartoon or

0:37:05.640 --> 0:37:08.879
<v Speaker 2>in an old Western is not a true indicator of

0:37:08.920 --> 0:37:13.840
<v Speaker 2>the potability of the water inside a saro cactus. I

0:37:13.960 --> 0:37:17.080
<v Speaker 2>have a vague recollection of maybe a Bugs Bunny cartoon

0:37:17.080 --> 0:37:20.040
<v Speaker 2>where someone just comes up to one of these cacti

0:37:20.160 --> 0:37:22.520
<v Speaker 2>and just slices it and then drinks out of it.

0:37:23.480 --> 0:37:25.360
<v Speaker 3>Yeah, that's my memory. When I was a kid, I

0:37:25.440 --> 0:37:27.360
<v Speaker 3>knew I didn't know much about the desert. But I

0:37:27.400 --> 0:37:29.480
<v Speaker 3>knew a few animal facts, and I knew that if

0:37:29.480 --> 0:37:31.399
<v Speaker 3>you're lost in the desert, you can drink water out

0:37:31.400 --> 0:37:31.960
<v Speaker 3>of a cactus.

0:37:32.040 --> 0:37:34.880
<v Speaker 2>Yeah, That's that's what we were taught via our media,

0:37:35.000 --> 0:37:39.080
<v Speaker 2>and this is absolutely not the case. The water inside

0:37:39.640 --> 0:37:43.320
<v Speaker 2>they're filled with water, but also high concentrations of acids

0:37:43.320 --> 0:37:47.360
<v Speaker 2>and alkaloids that falls short of like outright poison, but

0:37:47.480 --> 0:37:51.400
<v Speaker 2>would prove disastrous for human consumption, even in or perhaps

0:37:51.560 --> 0:37:53.600
<v Speaker 2>especially in a survival scenario.

0:37:54.120 --> 0:37:57.480
<v Speaker 3>What kind of disastrous like complex It just like gives

0:37:57.480 --> 0:37:58.759
<v Speaker 3>you diarrhea, Yeah, like that.

0:37:58.840 --> 0:38:01.200
<v Speaker 2>Sort of thing, Like do you on top of being

0:38:01.280 --> 0:38:04.160
<v Speaker 2>trapped in the desert and dealing with dehydration, do you

0:38:04.200 --> 0:38:07.640
<v Speaker 2>also need like chronic diarrhea on top of everything else?

0:38:08.200 --> 0:38:11.719
<v Speaker 2>You definitely do not. So, yeah, the water inside the

0:38:11.760 --> 0:38:15.799
<v Speaker 2>cactus is not good to go or anything like that. Now,

0:38:16.000 --> 0:38:19.360
<v Speaker 2>you know, We'll come back to the ways that humans

0:38:19.360 --> 0:38:23.880
<v Speaker 2>have used this particular species of cactus, because not to

0:38:23.880 --> 0:38:27.000
<v Speaker 2>say that it's off limits to humans. Humans have made

0:38:27.120 --> 0:38:30.160
<v Speaker 2>use of the swallow cactus for thousands of years, and

0:38:30.400 --> 0:38:33.160
<v Speaker 2>there are various valid ways for them to take advantage

0:38:33.200 --> 0:38:33.920
<v Speaker 2>of its moisture.

0:38:34.560 --> 0:38:37.000
<v Speaker 3>But it's not just like cut and cut and chug.

0:38:37.160 --> 0:38:39.960
<v Speaker 2>Yeah, no, no cutting chug, No sticking a spiggott in

0:38:40.000 --> 0:38:41.800
<v Speaker 2>it and then drinking from it like a water fountain

0:38:41.840 --> 0:38:44.400
<v Speaker 2>or what have you. It's a lot more complicated than that.

0:38:45.320 --> 0:38:47.200
<v Speaker 3>Well, folks, we just looked at the time and we

0:38:47.280 --> 0:38:51.000
<v Speaker 3>realized we really don't have time today to get into

0:38:51.040 --> 0:38:52.600
<v Speaker 3>some of the other stuff we were going to talk about,

0:38:52.640 --> 0:38:54.760
<v Speaker 3>So we're probably going to save some of those sections

0:38:54.760 --> 0:38:57.680
<v Speaker 3>for next time and come back and have even more

0:38:57.719 --> 0:39:00.680
<v Speaker 3>to say about them. So join us again for part two,

0:39:00.719 --> 0:39:02.359
<v Speaker 3>And this will be a great place to end part

0:39:02.400 --> 0:39:06.960
<v Speaker 3>one because it will direct extra special emphasis to the

0:39:07.320 --> 0:39:09.080
<v Speaker 3>advice to not just cut and chug.

0:39:09.440 --> 0:39:12.760
<v Speaker 2>Yes, yes, by all means, go out into the wild

0:39:13.000 --> 0:39:17.360
<v Speaker 2>and look upon these giants of the desert, but just

0:39:17.400 --> 0:39:19.719
<v Speaker 2>don't mess with them, don't shoot them, don't try to

0:39:19.800 --> 0:39:24.000
<v Speaker 2>drink them. Let them do their thing and you do yours.

0:39:24.120 --> 0:39:26.439
<v Speaker 2>And in the next episode we'll get into a little

0:39:26.480 --> 0:39:28.759
<v Speaker 2>bit more about what their thing is, and we'll talk

0:39:28.800 --> 0:39:33.640
<v Speaker 2>about the way that humans have utilized the suaro cactus,

0:39:33.760 --> 0:39:36.280
<v Speaker 2>you know, throughout their cohabitation with these giants.

0:39:36.520 --> 0:39:39.640
<v Speaker 3>Yeah, if you feel tempted to interact with them, you

0:39:39.680 --> 0:39:42.080
<v Speaker 3>can wave back to them. You know, you can mimic

0:39:42.120 --> 0:39:44.440
<v Speaker 3>their posture, you can cheer for them, you can tell

0:39:44.440 --> 0:39:45.040
<v Speaker 3>them it's good.

0:39:45.520 --> 0:39:49.120
<v Speaker 2>Yeah, yeah, I think Arizona State regulations would be okay

0:39:49.120 --> 0:39:52.600
<v Speaker 2>with that, not so much the blasting or the harvesting. Right,

0:39:53.120 --> 0:39:55.040
<v Speaker 2>all right, we're going to close it out then, but

0:39:55.040 --> 0:39:57.279
