1 00:00:00,280 --> 00:00:02,840 Speaker 1: Brought to you by the reinvented two thousand twelve camera. 2 00:00:03,160 --> 00:00:07,520 Speaker 1: It's ready. Are you welcome to stuff you should know 3 00:00:08,119 --> 00:00:16,479 Speaker 1: from house Stuff Works dot com. Hey, and welcome to 4 00:00:16,520 --> 00:00:19,240 Speaker 1: the podcast. I'm Josh Clark with me as always as 5 00:00:19,320 --> 00:00:24,080 Speaker 1: Charles W. Chuck bryant Y. How's it going? Oh, you know, Josh, 6 00:00:24,120 --> 00:00:27,560 Speaker 1: it's Monday. I don't think recording on mondays on either. 7 00:00:27,720 --> 00:00:30,560 Speaker 1: In the stupid room that you hate. My head hurts 8 00:00:30,600 --> 00:00:34,400 Speaker 1: to Jerry's all bummed out. What a wife? What are 9 00:00:34,400 --> 00:00:37,640 Speaker 1: we doing? I don't know. This isn't a big upper 10 00:00:37,680 --> 00:00:40,839 Speaker 1: of a topic either. The desertification, Yeah, maybe it's a 11 00:00:40,840 --> 00:00:42,840 Speaker 1: good thing. We're not in like some chipper mood. Yeah. 12 00:00:42,840 --> 00:00:46,480 Speaker 1: I think you're right because, as you know, Chuck, desertification 13 00:00:46,600 --> 00:00:52,120 Speaker 1: is one of the overlooked I think problems crises facing 14 00:00:52,200 --> 00:00:56,160 Speaker 1: humanity right now. Yeah, man, big time, Especially here in 15 00:00:56,240 --> 00:01:00,480 Speaker 1: the cushy US, especially in the very lush Southeastern US. 16 00:01:01,080 --> 00:01:03,200 Speaker 1: It's kind of easy to overlook. And we had like 17 00:01:03,240 --> 00:01:06,760 Speaker 1: a pretty huge drought a couple of years ago. Uh, 18 00:01:06,760 --> 00:01:08,920 Speaker 1: and you know we're like, oh no, we have slightly 19 00:01:09,000 --> 00:01:11,800 Speaker 1: less drinking water than we did before. Right, Well, there 20 00:01:11,800 --> 00:01:13,760 Speaker 1: were some other slight issues. We had some uprooting of 21 00:01:13,800 --> 00:01:17,640 Speaker 1: trees and such. Sure there was that. Uh, there wasn't 22 00:01:17,680 --> 00:01:21,920 Speaker 1: nearly as much boating or jet skiing as usual, which 23 00:01:21,959 --> 00:01:25,200 Speaker 1: I'm sure affected a lot of the gas stations around 24 00:01:25,319 --> 00:01:28,240 Speaker 1: some of the lakes. Right. There were probably some impacts 25 00:01:28,240 --> 00:01:31,360 Speaker 1: here and there that we didn't think about. Um, And 26 00:01:31,400 --> 00:01:35,399 Speaker 1: you're probably right. But it's also even easier to overlook 27 00:01:35,520 --> 00:01:40,560 Speaker 1: some of the impacts that take place during desertification in 28 00:01:40,760 --> 00:01:43,800 Speaker 1: some of the more marginalized societies in the world, right 29 00:01:44,200 --> 00:01:46,240 Speaker 1: for sure, So what are we looking at? I think 30 00:01:46,280 --> 00:01:50,920 Speaker 1: it's like of the people who live in areas that 31 00:01:50,960 --> 00:01:56,240 Speaker 1: are at risk of desertification are um, the poor under 32 00:01:56,280 --> 00:02:00,760 Speaker 1: the undeveloped countries, right right, Josh, it's about two billion people, 33 00:02:01,480 --> 00:02:04,960 Speaker 1: and for these people there's a kind of a slightly 34 00:02:04,960 --> 00:02:07,040 Speaker 1: more problems than not being able to jet ski as 35 00:02:07,120 --> 00:02:10,080 Speaker 1: much as one would like. Um. I think the infanmortality 36 00:02:10,200 --> 00:02:14,120 Speaker 1: rate is about ten times that of an industrialized nation, um, 37 00:02:14,160 --> 00:02:18,280 Speaker 1: and something like twenty four thousand people die every day 38 00:02:18,280 --> 00:02:21,920 Speaker 1: from starvation. A lot of these people are found in 39 00:02:22,840 --> 00:02:27,840 Speaker 1: desertified areas, right right, Let's get to the nitty gritty 40 00:02:27,880 --> 00:02:33,160 Speaker 1: of this, Chuck. What is desertification. I'm just gonna say 41 00:02:33,200 --> 00:02:39,160 Speaker 1: it in my words, desertification is when um uh natural 42 00:02:39,600 --> 00:02:42,960 Speaker 1: things take place and then man made things take place 43 00:02:43,440 --> 00:02:46,960 Speaker 1: to cause essentially what is the degradation of the soil 44 00:02:47,040 --> 00:02:51,000 Speaker 1: itself to where it will erode, things won't grow there, 45 00:02:51,760 --> 00:02:56,280 Speaker 1: and basically you're left with a barren desert landscape. That's 46 00:02:56,520 --> 00:02:59,520 Speaker 1: Chuck's definition. That's a good definition, Chuck. It's dead on. 47 00:03:00,360 --> 00:03:06,640 Speaker 1: The two chief processes that hasten desertification are um poor 48 00:03:06,800 --> 00:03:12,720 Speaker 1: soil management right and overuse of the land. Right. This 49 00:03:12,840 --> 00:03:16,240 Speaker 1: land is not meant to have lots and lots of 50 00:03:16,280 --> 00:03:20,680 Speaker 1: people and cattle grazing, not people grazing obviously, people farming 51 00:03:21,240 --> 00:03:23,880 Speaker 1: grazing right, and um with the land we're talking about 52 00:03:23,880 --> 00:03:28,920 Speaker 1: specifically or Sarai semi arid regions right right, And we 53 00:03:29,040 --> 00:03:31,160 Speaker 1: have one of those here in the United States. You 54 00:03:31,200 --> 00:03:34,200 Speaker 1: wouldn't think of it because it's artificially managed, but the 55 00:03:34,280 --> 00:03:39,280 Speaker 1: Great Plains are semi arid um And because of those 56 00:03:39,680 --> 00:03:45,040 Speaker 1: uh man made interventions like over use UM and intensive 57 00:03:45,040 --> 00:03:51,400 Speaker 1: farming techniques that didn't and not observing soil conservation, we 58 00:03:51,440 --> 00:03:56,920 Speaker 1: actually did experience desertification a century. Yeah, exactly. That's exactly 59 00:03:56,920 --> 00:03:59,960 Speaker 1: what happened. We got all these new fangled farming equipment 60 00:04:00,200 --> 00:04:03,520 Speaker 1: and said, hey, we're kind of poor because the depression 61 00:04:03,640 --> 00:04:05,760 Speaker 1: is coming up, and um, we need to use all 62 00:04:05,760 --> 00:04:09,160 Speaker 1: this stuff to really farm a lot. And that's what happened. 63 00:04:09,160 --> 00:04:11,160 Speaker 1: And then the dust bowl happened, and uh, but we 64 00:04:11,240 --> 00:04:13,400 Speaker 1: got it back well there there, Well, there was this 65 00:04:13,480 --> 00:04:16,600 Speaker 1: perfect storm that happened actually in the in the Midwest 66 00:04:16,800 --> 00:04:19,840 Speaker 1: in the late twenties. Since there was the Roaring twenties, 67 00:04:19,880 --> 00:04:23,640 Speaker 1: everybody was making tons of cash and farmers um started 68 00:04:23,680 --> 00:04:28,680 Speaker 1: borrowing heavily. Uh, and then the depression hit, much like today, 69 00:04:28,800 --> 00:04:34,320 Speaker 1: UM values of land dropped, the prices of UM commodities, 70 00:04:34,320 --> 00:04:38,719 Speaker 1: including agricultural products dropped, and people started having trouble making payments, 71 00:04:39,080 --> 00:04:43,680 Speaker 1: banks foreclosed. At the same time, the farmers were hit 72 00:04:43,800 --> 00:04:47,880 Speaker 1: really really hard financially. They were also hit really really 73 00:04:47,880 --> 00:04:52,480 Speaker 1: hard naturally because as they tried to step up farming 74 00:04:52,600 --> 00:04:57,000 Speaker 1: to increase yields, UM all they did was stripped the 75 00:04:57,040 --> 00:05:00,839 Speaker 1: land of its nutrients. And it became the this vicious 76 00:05:00,839 --> 00:05:04,480 Speaker 1: cycle where the harder they tried to cold stuff from 77 00:05:04,480 --> 00:05:07,080 Speaker 1: the land, the worse off it got. And then all 78 00:05:07,080 --> 00:05:10,200 Speaker 1: of a sudden, nothing would grow will bringing a drought, 79 00:05:10,279 --> 00:05:13,480 Speaker 1: which is the second component mother nature lending a hand, 80 00:05:14,040 --> 00:05:18,000 Speaker 1: and well, not a hand, a backhand. And uh, that's 81 00:05:18,080 --> 00:05:21,080 Speaker 1: when the dust bowl occurred, and we were in bad 82 00:05:21,080 --> 00:05:23,000 Speaker 1: shape in the Great Plains for a long time. Yeah. 83 00:05:23,040 --> 00:05:26,200 Speaker 1: Apparently these things were like the dust storms that came up. 84 00:05:27,080 --> 00:05:29,719 Speaker 1: Like trains would miss their stops in the middle of 85 00:05:29,760 --> 00:05:33,520 Speaker 1: these things because they couldn't see. Um. It's static electricity 86 00:05:33,600 --> 00:05:38,040 Speaker 1: is easily generated by these particles. So cars would stall. Um. 87 00:05:38,080 --> 00:05:41,320 Speaker 1: So people started dragging chains behind them to ground the 88 00:05:41,360 --> 00:05:45,720 Speaker 1: cars to keep them from stalling. Um. People would put 89 00:05:45,760 --> 00:05:48,719 Speaker 1: wet sheets up over their windows and like you would 90 00:05:48,760 --> 00:05:51,440 Speaker 1: have drifts of dust, like in your house with all 91 00:05:51,520 --> 00:05:53,400 Speaker 1: the doors and windows closed, it would still get in. 92 00:05:53,440 --> 00:05:57,400 Speaker 1: It was everywhere. Yeah, it was bad, bad news, bad times. Right, 93 00:05:57,520 --> 00:06:01,120 Speaker 1: So we got it back, we did it. Yeah, the 94 00:06:01,160 --> 00:06:05,160 Speaker 1: Great Plains farming once again, rich soil once again. And 95 00:06:05,160 --> 00:06:07,640 Speaker 1: that's a little teaser because we can we can combat this, 96 00:06:07,800 --> 00:06:09,680 Speaker 1: but we'll we'll get to that at the end. Right. 97 00:06:09,720 --> 00:06:13,000 Speaker 1: So it's happened here, it's happening in other places. It's 98 00:06:13,000 --> 00:06:16,520 Speaker 1: actually happening at a pretty rapid pace, isn't it. Chuck, Yes, 99 00:06:16,640 --> 00:06:20,279 Speaker 1: Josh stats are you calling for stats? Uh? New deserts 100 00:06:20,279 --> 00:06:22,560 Speaker 1: are growing at a rate of twenty thousand square miles 101 00:06:22,600 --> 00:06:26,440 Speaker 1: a year. And when you consider that half of the 102 00:06:26,480 --> 00:06:29,200 Speaker 1: total land mass of the Earth is dry land, intend 103 00:06:30,120 --> 00:06:34,440 Speaker 1: that land is already degraded, then it's not looking good. No, 104 00:06:34,680 --> 00:06:37,400 Speaker 1: it's not. And there's not a lot of processes in 105 00:06:37,480 --> 00:06:39,920 Speaker 1: place right now that are going to stop this. Although 106 00:06:40,480 --> 00:06:44,240 Speaker 1: we have a pretty clear picture of what's causing this, right, 107 00:06:44,240 --> 00:06:47,760 Speaker 1: like we said, poor soil conservation. Yeah, it's pretty easy 108 00:06:47,800 --> 00:06:50,120 Speaker 1: actually when you look at it's not like the most 109 00:06:50,120 --> 00:06:53,080 Speaker 1: complicated problem. Well, let's talk about the problem first, like, 110 00:06:53,120 --> 00:06:57,880 Speaker 1: what's what's going on? What's what causes desertification. Well, if 111 00:06:57,880 --> 00:07:00,640 Speaker 1: you're talking ecosystems like the human by and like any 112 00:07:00,680 --> 00:07:03,359 Speaker 1: living thing, you're looking for balance. What's the word we 113 00:07:03,480 --> 00:07:07,880 Speaker 1: used in the so an ecosystem wants balance as well, 114 00:07:08,560 --> 00:07:11,120 Speaker 1: and anything to throw it out of balance is not good, 115 00:07:11,160 --> 00:07:14,400 Speaker 1: which is what happens with desertification. When you get in 116 00:07:14,480 --> 00:07:20,560 Speaker 1: frequent rainfall, you lose um, what's called humus, which is 117 00:07:21,360 --> 00:07:26,200 Speaker 1: the really good organic top soil you want that plant 118 00:07:26,200 --> 00:07:30,200 Speaker 1: and animal material. Right, So, bobcats walking along gets struck 119 00:07:30,240 --> 00:07:33,800 Speaker 1: by lightning, falls over under the ground. What's going to 120 00:07:33,880 --> 00:07:37,239 Speaker 1: degrade and and be eaten by microbes and then turned 121 00:07:37,240 --> 00:07:43,760 Speaker 1: into humus which supports soil. Yeah, we're talking carbon, nitrogen, sulfur, phosphorus, 122 00:07:43,920 --> 00:07:46,400 Speaker 1: all these things that make your top soil really fertile. Right, 123 00:07:46,440 --> 00:07:50,320 Speaker 1: And there's nothing wrong with the semi arid region like it. 124 00:07:50,240 --> 00:07:53,480 Speaker 1: It's not a desert. You don't want to confuse the two. 125 00:07:53,880 --> 00:07:56,640 Speaker 1: The problem is when humans come in and say we 126 00:07:56,720 --> 00:07:59,240 Speaker 1: really need this land, this semi arid land, and we're 127 00:07:59,240 --> 00:08:01,800 Speaker 1: going to over use it, then it does become a desert. 128 00:08:02,080 --> 00:08:07,440 Speaker 1: And it becomes overused, um by not rotating crops, um, 129 00:08:07,560 --> 00:08:12,240 Speaker 1: by not using or over using chemical fertilizers, not composting 130 00:08:12,240 --> 00:08:16,360 Speaker 1: like you should, right exactly, and um kind of irresponsible 131 00:08:16,640 --> 00:08:20,360 Speaker 1: irrigation techniques right, allowing for runoff that kind of stuff. 132 00:08:20,720 --> 00:08:22,960 Speaker 1: The problem is is, like you said, humus is so 133 00:08:23,080 --> 00:08:28,000 Speaker 1: essential that if you if you strip the soil of 134 00:08:28,040 --> 00:08:32,720 Speaker 1: its humus, no matter how much rainfall comes along, it's 135 00:08:32,720 --> 00:08:36,520 Speaker 1: not going to restore that balance. Even worse, the rainfalls 136 00:08:36,559 --> 00:08:39,160 Speaker 1: is going to carry the soil away, just eroads it further, 137 00:08:39,200 --> 00:08:41,640 Speaker 1: which is the problem. So what are some of the 138 00:08:41,679 --> 00:08:44,480 Speaker 1: things that we're doing to to the semi arid regions. 139 00:08:44,520 --> 00:08:47,760 Speaker 1: Let's say a bunch of people suddenly come to a 140 00:08:47,800 --> 00:08:51,520 Speaker 1: semi arid region and say, we're gonna start farming here. 141 00:08:51,240 --> 00:08:53,920 Speaker 1: What are some of the uses of this land that 142 00:08:53,920 --> 00:08:59,600 Speaker 1: that can be problematic, well, grazing, grazing of cattle, like 143 00:08:59,640 --> 00:09:02,800 Speaker 1: irris sponsible grazing. What happens is a lot of poor 144 00:09:02,840 --> 00:09:06,719 Speaker 1: people might migrate to an area because their area has 145 00:09:06,720 --> 00:09:09,320 Speaker 1: been degraded. So you have a mass migration of people 146 00:09:09,920 --> 00:09:11,640 Speaker 1: that will bring in all their cows, so they're over 147 00:09:11,720 --> 00:09:13,760 Speaker 1: using the land. All of a sudden, the cows are grazing, 148 00:09:14,480 --> 00:09:16,679 Speaker 1: and you know, you can't fault them for saying it's 149 00:09:16,679 --> 00:09:19,959 Speaker 1: irresponsible grazing because they're trying to survive and they eat 150 00:09:19,960 --> 00:09:23,640 Speaker 1: all the grass. Let's say grasses is in trees are 151 00:09:23,720 --> 00:09:27,559 Speaker 1: essential for holding that top soil together, so once that's gone, 152 00:09:27,760 --> 00:09:30,920 Speaker 1: or firewood was another one, right, yeah, because if they're 153 00:09:30,960 --> 00:09:33,640 Speaker 1: looking for firewood, right, if you're using that fuel, then 154 00:09:33,679 --> 00:09:36,560 Speaker 1: they do like crazy, You're gonna cut down trees because 155 00:09:36,600 --> 00:09:38,440 Speaker 1: there's your fuel right there. And when you cut down 156 00:09:38,480 --> 00:09:41,520 Speaker 1: a bunch of trees, you actually um make the land 157 00:09:41,720 --> 00:09:45,400 Speaker 1: much more reflective, which dries out the atmosphere. It causes 158 00:09:45,520 --> 00:09:49,960 Speaker 1: more evaporation UM. And also once you lose that the 159 00:09:50,040 --> 00:09:52,640 Speaker 1: anchor for the soil, the soil gets kicked up as dust. 160 00:09:53,040 --> 00:09:56,880 Speaker 1: So the combination of that more UM, that drier climate, 161 00:09:57,360 --> 00:09:59,680 Speaker 1: plus the dust in the air means it's harder for 162 00:10:00,040 --> 00:10:03,360 Speaker 1: putation to form, making the the area even more arid. Yeah, 163 00:10:03,400 --> 00:10:05,480 Speaker 1: like compounds on itself. Sure, I got I got a 164 00:10:05,520 --> 00:10:07,520 Speaker 1: stat I was telling you that the mass migration of 165 00:10:07,559 --> 00:10:11,240 Speaker 1: people UH in the ninety nineties, dry land regions UM 166 00:10:11,440 --> 00:10:16,640 Speaker 1: grew eighteen point five percent in population. I mean, these 167 00:10:16,679 --> 00:10:18,760 Speaker 1: are places that shouldn't have that many people there anyway, 168 00:10:19,000 --> 00:10:23,120 Speaker 1: they're probably already overtaxed. Then mass migration happens, and it's 169 00:10:23,160 --> 00:10:25,520 Speaker 1: just a recipe for disaster, right, And the problem is 170 00:10:25,600 --> 00:10:29,120 Speaker 1: humans migrate a lot faster than land can be restored. Right. 171 00:10:29,720 --> 00:10:32,320 Speaker 1: So you you're you move from one place to another, 172 00:10:32,440 --> 00:10:35,240 Speaker 1: use that place up, you move to the next one. There, 173 00:10:35,320 --> 00:10:40,040 Speaker 1: there's you're eventually going to run out of places to move. Yeah, right, 174 00:10:40,480 --> 00:10:43,679 Speaker 1: that's what's happening. It is, And it's easy to overlook 175 00:10:43,920 --> 00:10:47,120 Speaker 1: here in the US, although I don't think we should, 176 00:10:47,200 --> 00:10:51,240 Speaker 1: because we we do have very um, we have really 177 00:10:51,240 --> 00:10:55,240 Speaker 1: good irrigation techniques in the Great Planes these days. But 178 00:10:55,400 --> 00:10:58,360 Speaker 1: if you look at it, it's we're not there's not 179 00:10:58,400 --> 00:11:00,520 Speaker 1: a bunch of people living on the Great Plains. It's 180 00:11:00,559 --> 00:11:05,439 Speaker 1: pretty sparsely populated. But humans in the US are virtually 181 00:11:05,480 --> 00:11:08,640 Speaker 1: represented on the Great Plains because you've got one percent 182 00:11:08,720 --> 00:11:12,160 Speaker 1: of Americans farming for the rest of America, right, So 183 00:11:12,240 --> 00:11:15,720 Speaker 1: there's like a virtual demand on that land through farming 184 00:11:16,120 --> 00:11:18,280 Speaker 1: because it produces the food we eat. So we may 185 00:11:18,280 --> 00:11:20,680 Speaker 1: not be living there, but we're using that land just 186 00:11:20,720 --> 00:11:23,840 Speaker 1: as if we were indigenous people all living on the 187 00:11:23,880 --> 00:11:27,959 Speaker 1: Great Plains. And the water that's used there actually is 188 00:11:28,040 --> 00:11:33,400 Speaker 1: virtually exported elsewhere, right, So we're we're putting in water 189 00:11:33,480 --> 00:11:37,600 Speaker 1: inputs there, it's growing, and we're taking that that water 190 00:11:37,800 --> 00:11:40,800 Speaker 1: basically and exporting it to the places where we eat 191 00:11:40,840 --> 00:11:43,040 Speaker 1: that food because we don't have to use the water here. 192 00:11:43,080 --> 00:11:46,400 Speaker 1: So it's like a virtual export of water. Interesting. Well, 193 00:11:46,440 --> 00:11:48,680 Speaker 1: the other thing to being American is we import a 194 00:11:48,679 --> 00:11:51,240 Speaker 1: lot of our food because we can afford to do so, 195 00:11:51,240 --> 00:11:53,360 Speaker 1: so we get food from all over the world. One 196 00:11:53,400 --> 00:11:57,559 Speaker 1: of the things that exacerbates the desertification is these migrating 197 00:11:57,640 --> 00:12:04,120 Speaker 1: poor people. They're rying on the natural ecosystem around them 198 00:12:04,160 --> 00:12:07,360 Speaker 1: pretty much only right, they can't afford to. Sometimes you 199 00:12:07,360 --> 00:12:09,560 Speaker 1: in regents where they just can't import anyway. Plus they 200 00:12:09,559 --> 00:12:12,640 Speaker 1: can't afford to because prices are skyrocketing for like wheat 201 00:12:12,640 --> 00:12:16,600 Speaker 1: and soy, So they need to use the grass that's 202 00:12:16,640 --> 00:12:19,120 Speaker 1: behind them and the cow that's eating it, and the 203 00:12:19,160 --> 00:12:22,000 Speaker 1: little tiny river full of dirty water. Because if you're 204 00:12:22,000 --> 00:12:25,679 Speaker 1: cutting down trees for fuel, you're probably not exporting a 205 00:12:25,679 --> 00:12:28,920 Speaker 1: lot of stuff. I got another staff for you. You're 206 00:12:28,920 --> 00:12:33,000 Speaker 1: ready to be creeped out. Uh, fifty million people will 207 00:12:33,040 --> 00:12:36,200 Speaker 1: be displaced by desertification in the next ten years and 208 00:12:36,440 --> 00:12:39,080 Speaker 1: I saw that, so says people in planet dot net. 209 00:12:39,160 --> 00:12:41,079 Speaker 1: That's a lot of people. That's a lot of people, 210 00:12:41,520 --> 00:12:43,440 Speaker 1: and they're going to places like we said, that's not 211 00:12:43,520 --> 00:12:47,880 Speaker 1: aren't necessarily you know, fertile oasis anyway. So it's just 212 00:12:47,920 --> 00:12:50,599 Speaker 1: making everything worse. And again, if you don't have the 213 00:12:50,640 --> 00:12:53,000 Speaker 1: money to import food, you don't have the money to 214 00:12:53,320 --> 00:12:59,319 Speaker 1: virtually import water. Hence the thousand people that die every 215 00:12:59,360 --> 00:13:03,480 Speaker 1: day of starvation, yeah every day. Wow, it's very sad. 216 00:13:03,520 --> 00:13:07,760 Speaker 1: Stat Like you said, the chuck um, So just let's 217 00:13:08,400 --> 00:13:11,600 Speaker 1: provide a quick recap, right, you've got a semi arid 218 00:13:11,640 --> 00:13:14,600 Speaker 1: region that looks kind of lush, you know, it doesn't 219 00:13:14,600 --> 00:13:17,679 Speaker 1: look like a desert. You come in, you start planting, 220 00:13:18,040 --> 00:13:22,640 Speaker 1: you use too much chemical fertilizer, you overgraze, you cut 221 00:13:22,640 --> 00:13:26,080 Speaker 1: down trees for fuel. You're and you're making a living. 222 00:13:26,480 --> 00:13:29,119 Speaker 1: A few people can do this and it can be sustainable, 223 00:13:29,160 --> 00:13:32,599 Speaker 1: but when too many people start doing it, then the 224 00:13:32,600 --> 00:13:36,880 Speaker 1: the humus is lost in the soil and uh, the 225 00:13:36,960 --> 00:13:40,640 Speaker 1: land starts reflecting back into the sky. So precipitation goes down, 226 00:13:40,800 --> 00:13:44,720 Speaker 1: the soil is loose, storms blow in and you've got nothing. 227 00:13:44,760 --> 00:13:47,280 Speaker 1: You have desert, erosion and desert. Yeah, how do you 228 00:13:47,360 --> 00:13:52,400 Speaker 1: combat this? Well, Josh, it's not easy. It's actually fundamentally easy, 229 00:13:52,480 --> 00:13:55,080 Speaker 1: but it's hard because not enough people are taking part, 230 00:13:55,400 --> 00:13:57,559 Speaker 1: and it's such a it needs to be done in 231 00:13:57,600 --> 00:14:00,760 Speaker 1: such a massive scale, right, Exactly what you have to 232 00:14:00,800 --> 00:14:03,679 Speaker 1: do is start at a grassroots level, That's what they say, 233 00:14:04,360 --> 00:14:06,720 Speaker 1: and you need to go in there with people like 234 00:14:06,760 --> 00:14:08,240 Speaker 1: the u N I know as a group will plug 235 00:14:08,240 --> 00:14:09,800 Speaker 1: them in a second. And you go in and you 236 00:14:09,800 --> 00:14:13,000 Speaker 1: teach these people long term benefits, teaching them to think 237 00:14:13,040 --> 00:14:16,600 Speaker 1: long term as far as rotating crops terracing the land 238 00:14:16,720 --> 00:14:20,640 Speaker 1: proper irrigation techniques so they're not so shortsighted and just 239 00:14:20,680 --> 00:14:24,640 Speaker 1: trying to get the crops this year. You gotta teach them. 240 00:14:24,760 --> 00:14:26,960 Speaker 1: That's hard to do. That's what we did in the 241 00:14:27,080 --> 00:14:31,120 Speaker 1: UM late thirties and early forties. The federal government UM 242 00:14:31,360 --> 00:14:34,320 Speaker 1: was like, wow, we our nation's bread basket is a desert. 243 00:14:34,360 --> 00:14:36,760 Speaker 1: Now we have to do something. But they determined that 244 00:14:36,800 --> 00:14:42,960 Speaker 1: they couldn't constitutionally force farmers to use improve soil techniques. 245 00:14:43,320 --> 00:14:45,920 Speaker 1: So they turned to the states to basically force them 246 00:14:45,960 --> 00:14:49,680 Speaker 1: to and they created soil conservation districts UH and made 247 00:14:49,720 --> 00:14:54,960 Speaker 1: it virtually free to farm and and undertake these soil 248 00:14:55,000 --> 00:14:57,680 Speaker 1: conservation techniques. So they're like, we're gonna provide you with 249 00:14:57,760 --> 00:15:01,280 Speaker 1: everything you need. Just do this right. UM. Use contour 250 00:15:01,440 --> 00:15:05,400 Speaker 1: plowing to to trap water better when you arrogate. UM. 251 00:15:05,640 --> 00:15:10,000 Speaker 1: The federal government also planted between nineteen thirty five and 252 00:15:10,160 --> 00:15:14,800 Speaker 1: nineteen forty two hundred and eighty five thousand miles of trees. Yeah. 253 00:15:14,840 --> 00:15:17,120 Speaker 1: That's a huge one because trees not only do they 254 00:15:17,120 --> 00:15:19,080 Speaker 1: help keep the soil together with the root system, but 255 00:15:19,120 --> 00:15:22,840 Speaker 1: they block the wind, and the wind causes a lot 256 00:15:22,840 --> 00:15:26,520 Speaker 1: of erosion Yeah, this is all easier done in America. Obviously, 257 00:15:26,960 --> 00:15:28,760 Speaker 1: you got we got our work cut out against us 258 00:15:28,920 --> 00:15:32,360 Speaker 1: for developing nations. Well yeah, and but China, I mean, 259 00:15:32,360 --> 00:15:34,400 Speaker 1: they're they're starting to get a little more cash in 260 00:15:34,400 --> 00:15:36,200 Speaker 1: their pocket than they have before. And they have a 261 00:15:36,280 --> 00:15:40,120 Speaker 1: huge problem with desertification. Is the Gobi is creeping closer 262 00:15:40,160 --> 00:15:45,800 Speaker 1: and closer towards Beijing. Apparently dust storm from the Gobi 263 00:15:46,280 --> 00:15:49,760 Speaker 1: that covers Beijing are some of them are so enormous 264 00:15:49,800 --> 00:15:54,160 Speaker 1: that they can be detected in the States. Yeah, big 265 00:15:54,240 --> 00:15:56,640 Speaker 1: dust storm. It is. China is taking action though. They 266 00:15:56,720 --> 00:15:59,640 Speaker 1: built a or there in the process of planning a 267 00:15:59,760 --> 00:16:02,720 Speaker 1: three thousand mile long belt of trees along the edge 268 00:16:02,760 --> 00:16:05,760 Speaker 1: of the Gobi, which is gonna help. And um, I 269 00:16:05,800 --> 00:16:08,480 Speaker 1: think what other countries doing that? And uh oh along 270 00:16:08,480 --> 00:16:10,960 Speaker 1: the Sahara Desert they're gonna they're trying to build a 271 00:16:11,000 --> 00:16:13,560 Speaker 1: similar like they're calling it a green wall, right, And 272 00:16:13,600 --> 00:16:16,480 Speaker 1: there's a German company, actually it's not a company, they're 273 00:16:16,480 --> 00:16:20,120 Speaker 1: out of Bremen University. Um. They figured out that if 274 00:16:20,120 --> 00:16:24,840 Speaker 1: you take coffee sacks like jute sacks, um fill them 275 00:16:24,880 --> 00:16:28,120 Speaker 1: with this uh this kind of gel that can hold 276 00:16:28,160 --> 00:16:30,560 Speaker 1: like a thousand times it's wede in water or something 277 00:16:30,600 --> 00:16:36,760 Speaker 1: like that. Seeds compost and uh it is it's like 278 00:16:36,800 --> 00:16:40,120 Speaker 1: a huge seed bomb. You can drop them out around 279 00:16:40,120 --> 00:16:43,160 Speaker 1: the desert and they will or at least a semi 280 00:16:43,240 --> 00:16:46,640 Speaker 1: arid region and they will take root, uh after just 281 00:16:46,680 --> 00:16:49,880 Speaker 1: a few rainfalls. You can also put them in between 282 00:16:50,000 --> 00:16:53,800 Speaker 1: trees and just leave the trees and those trees will grow. 283 00:16:53,840 --> 00:16:56,840 Speaker 1: I think they had success rate with the type of 284 00:16:56,880 --> 00:16:59,440 Speaker 1: holly tree that they were trying to grow. They plant 285 00:16:59,480 --> 00:17:02,000 Speaker 1: two of them and then put one of these bags 286 00:17:02,000 --> 00:17:05,320 Speaker 1: in between them. Yeah, that's awesome. Um. The other thing 287 00:17:05,359 --> 00:17:08,280 Speaker 1: I thought was cool in the article was that the 288 00:17:08,280 --> 00:17:11,720 Speaker 1: writer talked a little bit about sometimes the old traditional techniques, 289 00:17:11,800 --> 00:17:15,119 Speaker 1: the ancient techniques, they were like really on target with 290 00:17:15,119 --> 00:17:17,520 Speaker 1: what they were doing, and sometimes a modern way doesn't 291 00:17:17,520 --> 00:17:20,359 Speaker 1: work as well. So in Spain, uh, and a British 292 00:17:20,440 --> 00:17:23,640 Speaker 1: company has been renovating in a one thousand year old 293 00:17:23,640 --> 00:17:27,480 Speaker 1: Moorish irrigation system. Yeah. How cool is that? It's just 294 00:17:27,560 --> 00:17:31,879 Speaker 1: cool that there's a thousand year old irrigation systems. Yeah, Chuck, 295 00:17:32,000 --> 00:17:36,960 Speaker 1: there's um. I mean, unless you feel like going to 296 00:17:37,520 --> 00:17:41,120 Speaker 1: China or subs are in Africa and plant trees, there's 297 00:17:41,160 --> 00:17:42,760 Speaker 1: not a lot you could do. Is like the stuff 298 00:17:42,760 --> 00:17:47,960 Speaker 1: you should know listener, right, except yeah, Um, one of 299 00:17:48,000 --> 00:17:52,960 Speaker 1: the one of the key ways of preventing desertification or 300 00:17:53,480 --> 00:17:58,639 Speaker 1: slowing it, I guess is encouraging um indigenous societies to 301 00:17:59,160 --> 00:18:04,359 Speaker 1: look for alter native means of sustaining themselves. I guess 302 00:18:04,480 --> 00:18:07,720 Speaker 1: besides farming and agriculture, right, and you know there's things 303 00:18:07,760 --> 00:18:12,320 Speaker 1: like growing herbs and uh things you can make oil 304 00:18:12,359 --> 00:18:14,560 Speaker 1: extracts from and using them soaps and stuff like that. 305 00:18:15,080 --> 00:18:17,440 Speaker 1: So I guess if you wanted to do something here 306 00:18:17,480 --> 00:18:22,080 Speaker 1: in the States or in Norway, you would maybe kind 307 00:18:22,080 --> 00:18:24,160 Speaker 1: of look for something like that and start buying them 308 00:18:24,280 --> 00:18:27,920 Speaker 1: on mass online. Does your does Emily sell those on 309 00:18:28,200 --> 00:18:31,440 Speaker 1: Love Your Mama? Well, she sells around soaps, but she doesn't. 310 00:18:31,480 --> 00:18:33,840 Speaker 1: Does she use oils from the Gobi or anything? No, 311 00:18:34,040 --> 00:18:37,760 Speaker 1: she tries to buy local. Actually, right, that's not local. No, No, 312 00:18:37,840 --> 00:18:39,800 Speaker 1: it's not that local. I'm gonna shame her for not 313 00:18:39,800 --> 00:18:42,399 Speaker 1: shipping in her essential oils from the Guppy consort. Right. 314 00:18:42,680 --> 00:18:45,399 Speaker 1: You got anything else on desertification? Yeah, just if you 315 00:18:45,400 --> 00:18:47,600 Speaker 1: want to read a little bit more on how you 316 00:18:47,640 --> 00:18:50,280 Speaker 1: can participate or at least support and write letters that 317 00:18:50,359 --> 00:18:53,040 Speaker 1: kind of thing. Uh. The u n has a cool site, 318 00:18:53,080 --> 00:18:57,639 Speaker 1: the United Nations Convention to Combat Desertification, and that is 319 00:18:57,760 --> 00:19:01,080 Speaker 1: u N C C D DOT I N T and 320 00:19:01,160 --> 00:19:05,359 Speaker 1: you can click on action programs and that's programs spelled 321 00:19:05,359 --> 00:19:08,400 Speaker 1: with two ms and any. Yeah, British, they're silly that way, 322 00:19:09,040 --> 00:19:11,399 Speaker 1: so it's pretty cool. You can click on action programs 323 00:19:11,400 --> 00:19:13,760 Speaker 1: and they have it. There isn't one action program because 324 00:19:13,760 --> 00:19:15,879 Speaker 1: it's got to be very specific to the land. So 325 00:19:16,000 --> 00:19:17,680 Speaker 1: you click on that and you can go to Africa 326 00:19:17,760 --> 00:19:20,879 Speaker 1: and you can go to a subregion of Botswana and 327 00:19:20,960 --> 00:19:23,440 Speaker 1: find out like you can download a pdf to see 328 00:19:23,480 --> 00:19:25,600 Speaker 1: exactly what they're trying to do. So cool, it's kind 329 00:19:25,600 --> 00:19:27,800 Speaker 1: of cool just to educate yourself. Or you can start 330 00:19:27,840 --> 00:19:31,000 Speaker 1: collecting juke coffee bags and mail them to Bremen University. 331 00:19:31,840 --> 00:19:35,440 Speaker 1: Here you go if you want to know more about desertification, 332 00:19:35,680 --> 00:19:40,639 Speaker 1: arguably the greatest crisis humanity faces. Right now, you can 333 00:19:40,840 --> 00:19:43,240 Speaker 1: type that word and remember just one s in the 334 00:19:43,280 --> 00:19:45,920 Speaker 1: handy search bar at how stuff worst dot com, which 335 00:19:45,920 --> 00:19:51,880 Speaker 1: means it's time for a listener mail. Indeed, Josh, I'm 336 00:19:51,920 --> 00:19:57,040 Speaker 1: gonna call this those crazy wacky Aussies. Okay, we have 337 00:19:57,080 --> 00:19:59,600 Speaker 1: a lot of AUSI listeners. We hear from them quite 338 00:19:59,600 --> 00:20:03,199 Speaker 1: a bit, and uh, they're they're wacky people and we 339 00:20:03,200 --> 00:20:05,560 Speaker 1: need to make it down there at some point, although 340 00:20:05,560 --> 00:20:07,359 Speaker 1: I don't think you could ever stomach that flight, could you. 341 00:20:08,280 --> 00:20:12,640 Speaker 1: I'm going to Japan. It's fourteen hours. Good luck. Uh. 342 00:20:12,680 --> 00:20:15,879 Speaker 1: This comes from Chris from Australia. I listen to your 343 00:20:15,880 --> 00:20:18,440 Speaker 1: podcasts all the time. I'm sure it's a clinical addiction. 344 00:20:18,960 --> 00:20:22,000 Speaker 1: And I thought you needed to know about cow pat latto. 345 00:20:22,600 --> 00:20:24,760 Speaker 1: You know what a cow pad is. It's poop, yeah, 346 00:20:24,880 --> 00:20:28,760 Speaker 1: cow pie, cow poop. Cow pat latto is recognized but 347 00:20:28,840 --> 00:20:32,720 Speaker 1: certainly not common event in rural Australia where a paddock 348 00:20:33,320 --> 00:20:35,400 Speaker 1: is plotted into sections. I don't know what you would 349 00:20:35,440 --> 00:20:37,600 Speaker 1: call it. I don't know, an area of land. Maybe 350 00:20:37,600 --> 00:20:39,760 Speaker 1: you call it a paddock. That's what he says. That's 351 00:20:39,760 --> 00:20:42,680 Speaker 1: what I've always called So they split it into sections. 352 00:20:42,880 --> 00:20:46,840 Speaker 1: That's all done on paper like a Cartesian coordinate. Gamblers 353 00:20:46,840 --> 00:20:49,280 Speaker 1: will bet their money on a particular portion of said paddock. 354 00:20:49,640 --> 00:20:51,359 Speaker 1: When it's decided that it's time to get on with 355 00:20:51,400 --> 00:20:55,080 Speaker 1: the game, a farm animal, traditionally bovine you know what's coming, 356 00:20:55,920 --> 00:20:58,320 Speaker 1: is thrown in the paddock gamblers and other locals and 357 00:20:58,400 --> 00:21:02,119 Speaker 1: sit around, eating and drinking and generally making merry and 358 00:21:02,160 --> 00:21:06,120 Speaker 1: wait for said bovine to take a crap. So when 359 00:21:06,160 --> 00:21:10,960 Speaker 1: the aforementioned cow has uh taking his poopoo, its coordinates 360 00:21:10,960 --> 00:21:14,440 Speaker 1: are taken and the winner is whoever's plot the poopoo 361 00:21:14,520 --> 00:21:18,880 Speaker 1: has landed in. Obviously, prizes I don't know, maybe the money. 362 00:21:18,960 --> 00:21:22,680 Speaker 1: Maybe they wait for a second and third prize, although 363 00:21:22,720 --> 00:21:27,040 Speaker 1: this would indicate an unhealthy cow. It keeps going, and 364 00:21:27,119 --> 00:21:29,240 Speaker 1: maybe they get a turkey or a meat tray, or 365 00:21:29,280 --> 00:21:32,480 Speaker 1: a slab of beer or something where I get confused. Wait, 366 00:21:32,480 --> 00:21:35,320 Speaker 1: a slab of beer is that a case? I don't know. 367 00:21:35,359 --> 00:21:39,760 Speaker 1: Maybe it's Australian for cakes right. Anyway, it's generally used 368 00:21:39,760 --> 00:21:41,800 Speaker 1: as a fundraiser, like a local raffle, so it's like 369 00:21:41,840 --> 00:21:44,240 Speaker 1: a fundraising thing. And then she said there's like ladies 370 00:21:44,320 --> 00:21:46,840 Speaker 1: having baked sales and the guys are all sitting around 371 00:21:46,840 --> 00:21:51,879 Speaker 1: getting hammered. Basically, generally it's a great excuse for us 372 00:21:51,880 --> 00:21:55,720 Speaker 1: suck more And that is an Australian synonym for a 373 00:21:55,760 --> 00:21:58,920 Speaker 1: shin dig, a hoot nanny, a party, or a booze up. 374 00:21:59,119 --> 00:22:01,560 Speaker 1: They call it a suck more Okay, so that's from 375 00:22:01,640 --> 00:22:06,800 Speaker 1: Chris Australia red Hair. Nice. Thanks Chris. So now we 376 00:22:06,840 --> 00:22:10,720 Speaker 1: know about desertification and suck mors.
