1 00:00:00,280 --> 00:00:02,920 Speaker 1: Brought to you by the reinvented two thousand twelve Camray. 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 --> 00:00:16,239 Speaker 1: from House Stuff Works dot com. Hey, and welcome to 4 00:00:16,239 --> 00:00:19,599 Speaker 1: the podcast. I'm Josh Clark, that's Charles W. Chuck Bryant, 5 00:00:19,760 --> 00:00:22,919 Speaker 1: and we're doing this again. We're bringing the science this 6 00:00:23,000 --> 00:00:30,480 Speaker 1: time for once in our lives. Acid Rain, Yeah, boarding 7 00:00:30,600 --> 00:00:34,400 Speaker 1: down from the acid clouds. That's not how that song goes. 8 00:00:35,000 --> 00:00:37,880 Speaker 1: That's not how acid rain by Dejoon Daego. That guy 9 00:00:38,040 --> 00:00:39,760 Speaker 1: so great. We watched that again the other day just 10 00:00:39,840 --> 00:00:42,519 Speaker 1: by a chance, and I hadn't seen it in a 11 00:00:42,560 --> 00:00:45,519 Speaker 1: couple of years, and it's still just he's hard to like, 12 00:00:45,720 --> 00:00:47,720 Speaker 1: Chad said our friend, it's hard to believe that that's 13 00:00:47,800 --> 00:00:50,519 Speaker 1: voice comes out of that guy. And he's kind a 14 00:00:50,520 --> 00:00:54,480 Speaker 1: new one, like mother Economy really good. Yeah, yeah, he's 15 00:00:54,480 --> 00:00:57,760 Speaker 1: a good guy. Um. I don't know what chocolate Rains about, 16 00:00:57,840 --> 00:01:01,040 Speaker 1: but there's a good call out. I would be very 17 00:01:01,120 --> 00:01:04,959 Speaker 1: interested to hear everyone's interpretation of what chocolate rain means 18 00:01:06,920 --> 00:01:12,920 Speaker 1: that too. Um, let's see, Chuck, do you remember back 19 00:01:13,200 --> 00:01:21,080 Speaker 1: in the eighties hearing about two things too terrifying environmental things. 20 00:01:21,440 --> 00:01:26,880 Speaker 1: One the Ozone layer, specifically the whole in the ozone layer, 21 00:01:28,040 --> 00:01:32,160 Speaker 1: and two acid rain, you throw an apartheid and that 22 00:01:32,280 --> 00:01:37,600 Speaker 1: is the eighties. Yeah, I'm not gonna play sen City nope. Um, yeah, 23 00:01:37,640 --> 00:01:41,560 Speaker 1: that's pretty much. Also, don't forget cocaine, Ronald Reagan, jelly 24 00:01:41,600 --> 00:01:47,640 Speaker 1: Beans and the team and Magnum. But he kind of 25 00:01:47,640 --> 00:01:49,880 Speaker 1: transcends the eighties. Really, if you ask me, he's just 26 00:01:50,320 --> 00:01:55,120 Speaker 1: a man of all times, never gets old. Um. The 27 00:01:55,160 --> 00:01:58,040 Speaker 1: weird thing is this, since I guess maybe the mid 28 00:01:58,160 --> 00:02:00,440 Speaker 1: nineties or whatever, you don't hear about any of those 29 00:02:00,440 --> 00:02:05,080 Speaker 1: things except for Magnum any longer. Yeah, because of course 30 00:02:05,160 --> 00:02:08,239 Speaker 1: global warming took over and everyone's afraid we're gonna melt now, 31 00:02:08,760 --> 00:02:10,480 Speaker 1: and so they said, well, we don't need to worry 32 00:02:10,480 --> 00:02:12,560 Speaker 1: about acid rain anymore. We fix that problem. Right. I 33 00:02:12,600 --> 00:02:15,160 Speaker 1: think there's a perception that, you know, acid rain was 34 00:02:15,240 --> 00:02:19,040 Speaker 1: fixed and taken care of, and astoundingly in a lot 35 00:02:19,080 --> 00:02:22,560 Speaker 1: of ways, it has been. Yeah, they've come a long way, baby. 36 00:02:22,800 --> 00:02:24,880 Speaker 1: Those Onlaer, by the way, has not been. As a 37 00:02:24,880 --> 00:02:27,119 Speaker 1: matter of fact, another one opened up in the Antarctic. 38 00:02:27,200 --> 00:02:31,080 Speaker 1: Now we have two. But that's a that's another topic 39 00:02:31,080 --> 00:02:33,840 Speaker 1: of discussion. Acid rain let's get back to it though. 40 00:02:34,000 --> 00:02:36,519 Speaker 1: Is a very Uh. It's a nice success story in 41 00:02:36,560 --> 00:02:39,640 Speaker 1: a lot of ways. And it came from a comprehensive 42 00:02:40,240 --> 00:02:45,200 Speaker 1: understanding of a problem and a comprehensive will to address it. 43 00:02:45,600 --> 00:02:48,639 Speaker 1: That's right, that's how you take care of stuff. There 44 00:02:48,720 --> 00:02:51,600 Speaker 1: is still a long way to go, though, I was 45 00:02:51,880 --> 00:02:54,440 Speaker 1: bringing me back down earth. Not completely fixed, but it 46 00:02:54,520 --> 00:02:56,959 Speaker 1: is good. It's heartwarming to know that you can see 47 00:02:57,000 --> 00:03:02,720 Speaker 1: a problem and and reduce something like acid rain precisely, so, Chuck, 48 00:03:02,800 --> 00:03:07,720 Speaker 1: what is acid rain? Acid rain, Josh, is a transboundary issue, 49 00:03:07,840 --> 00:03:11,920 Speaker 1: which means even though it just occurs in the mainly 50 00:03:11,960 --> 00:03:14,720 Speaker 1: occurs in the Northern Hemisphere, it still is going to 51 00:03:14,960 --> 00:03:17,400 Speaker 1: cross over and affect the rest of the world. And 52 00:03:17,440 --> 00:03:20,440 Speaker 1: the reason that's worth mentioning is because for many years, 53 00:03:20,520 --> 00:03:24,200 Speaker 1: up until the nighties, um, they thought it was a 54 00:03:24,280 --> 00:03:27,960 Speaker 1: very local problem. Uh, and then they realized, oh no, 55 00:03:28,200 --> 00:03:30,560 Speaker 1: it's not, and everybody kind of got on board with 56 00:03:30,639 --> 00:03:33,720 Speaker 1: fixing it. That's ry Um. But like you said, Northern Hemisphere, 57 00:03:34,480 --> 00:03:38,760 Speaker 1: it occurs mostly there because we're the dirtiest, more industrial, 58 00:03:39,040 --> 00:03:43,800 Speaker 1: most polluting. Yeah. So specifically, what it is, um is 59 00:03:45,000 --> 00:03:49,920 Speaker 1: rain with acid in it. Literally, Uh, emissions of sulfur dioxide, 60 00:03:50,120 --> 00:03:54,040 Speaker 1: s O two, nitrogen oxides and O X from things 61 00:03:54,120 --> 00:03:57,200 Speaker 1: like cars and factories, power plants, all those nasty things, 62 00:03:57,320 --> 00:04:02,360 Speaker 1: Lightning strikes, volcanoes, the natural ones. Um. They will actually 63 00:04:02,560 --> 00:04:07,240 Speaker 1: react with water vapor in the atmosphere and turn into acid, 64 00:04:07,280 --> 00:04:10,920 Speaker 1: sulfuric and nitric acids, and they can fall in the 65 00:04:10,960 --> 00:04:15,400 Speaker 1: form of wet rain, um, snow, sleep, bog or they 66 00:04:15,440 --> 00:04:21,599 Speaker 1: can be deposited as particulates and gases. That's dry acid rain. Well, 67 00:04:21,680 --> 00:04:24,960 Speaker 1: the whole dry things called acid depositions because it can 68 00:04:25,000 --> 00:04:28,760 Speaker 1: be wet or dry, right, and it's being deposited exactly 69 00:04:28,800 --> 00:04:31,640 Speaker 1: on the earth. Yeah, that's what that word is. It's 70 00:04:31,680 --> 00:04:34,279 Speaker 1: branched from deposit, isn't it. I think so, Yeah, it 71 00:04:34,320 --> 00:04:37,840 Speaker 1: didn't even occur to me. Um and so you so 72 00:04:38,680 --> 00:04:43,200 Speaker 1: bravo unexplaining acid rain, and bravo Sarah Dowdy who wrote this. Yeah, 73 00:04:43,240 --> 00:04:45,720 Speaker 1: she did a very good job on this. UM. And 74 00:04:46,000 --> 00:04:48,920 Speaker 1: when you can't just be like, well this this rain 75 00:04:48,960 --> 00:04:51,360 Speaker 1: seems a little hanky, So we're gonna say that that's 76 00:04:51,400 --> 00:04:55,080 Speaker 1: acid rain. They actually know. Um, there's a there's a 77 00:04:55,160 --> 00:05:00,200 Speaker 1: very um strict definition of what constitutes acid rain. And 78 00:05:00,240 --> 00:05:02,560 Speaker 1: then they use the pH scale to determine it. Good 79 00:05:02,600 --> 00:05:05,600 Speaker 1: old pH scale. So the pH scale is um this 80 00:05:05,839 --> 00:05:10,960 Speaker 1: spectrum between highly acidic and highly basic, right and um. 81 00:05:11,040 --> 00:05:14,719 Speaker 1: Acid rain obviously falls towards the acidic side of the scale, 82 00:05:15,000 --> 00:05:17,920 Speaker 1: and in the middle of this scale is pure water. 83 00:05:18,520 --> 00:05:21,280 Speaker 1: And that's at a seven point. Oh, it's not at zero. 84 00:05:21,480 --> 00:05:24,599 Speaker 1: It's entirely neutral. It's neither basic nor acidic. Yeah. I 85 00:05:24,640 --> 00:05:27,559 Speaker 1: just find it interesting that it's a scale of zero 86 00:05:27,600 --> 00:05:30,680 Speaker 1: to fourteen with seven being in the middle. Seven's in 87 00:05:30,720 --> 00:05:32,800 Speaker 1: the middle of zero to fourteen. Yeah, but I mean 88 00:05:32,880 --> 00:05:36,120 Speaker 1: it just for me, I would say zero is neutral 89 00:05:36,320 --> 00:05:39,839 Speaker 1: and anything above would be negative. But whatever. In the 90 00:05:39,880 --> 00:05:43,720 Speaker 1: grand tradition of Um civilization established by the Romans, though, 91 00:05:43,760 --> 00:05:47,679 Speaker 1: the pH scale starts at one rather than zero. Um. 92 00:05:47,880 --> 00:05:51,600 Speaker 1: But yeah, I see what you're saying. Actually here, I 93 00:05:51,680 --> 00:05:54,160 Speaker 1: like the fact I think it goes from one to fourteen. Well, 94 00:05:54,160 --> 00:05:58,040 Speaker 1: then Sarah got it wrong. Um, in the the graph 95 00:05:58,160 --> 00:06:02,559 Speaker 1: here says one to fourteen. I wonder, um, but back 96 00:06:02,560 --> 00:06:10,320 Speaker 1: to its seventh in the middle either way, seven, Yeah, 97 00:06:10,839 --> 00:06:13,800 Speaker 1: so it would start a zero. I guess. Um. So 98 00:06:14,760 --> 00:06:18,000 Speaker 1: the more acidic is the lower numbers, and the more 99 00:06:18,040 --> 00:06:21,480 Speaker 1: basic is the higher numbers. Right. The thing is is 100 00:06:21,680 --> 00:06:26,039 Speaker 1: rain isn't neutral. Normal rain still is slightly acidic, and 101 00:06:26,080 --> 00:06:30,600 Speaker 1: it hits about five point six on the pH scale. Right, 102 00:06:31,080 --> 00:06:35,280 Speaker 1: Um so why well, it combines with carbon dioxide in 103 00:06:35,320 --> 00:06:41,159 Speaker 1: the atmosphere to form a slightly acidic um carbonic acid deposition, 104 00:06:42,040 --> 00:06:46,279 Speaker 1: which is branch from the root word deposit um. So 105 00:06:46,440 --> 00:06:50,080 Speaker 1: uh so acid rain is something like five point three 106 00:06:50,200 --> 00:06:54,560 Speaker 1: to four point oh as far as um acidity goes, right, 107 00:06:54,680 --> 00:06:58,719 Speaker 1: four point three to five okay, Um, yeah, that's a 108 00:06:58,720 --> 00:07:03,240 Speaker 1: big difference. Um, And it's something like what the acidity 109 00:07:03,880 --> 00:07:07,320 Speaker 1: between orange juice and black coffee? Yeah, which Sarah is 110 00:07:07,400 --> 00:07:09,960 Speaker 1: keen to point out, which is a bit of a misnomer. 111 00:07:09,960 --> 00:07:11,840 Speaker 1: While that's true, you can't say, well, like well it's 112 00:07:11,880 --> 00:07:13,600 Speaker 1: just like coffee and then you're like that's not gonna 113 00:07:13,880 --> 00:07:15,880 Speaker 1: still coffe in your grass and it's not gonna kill it. 114 00:07:16,240 --> 00:07:20,120 Speaker 1: See I'm and yeah, my hat was off to her 115 00:07:20,200 --> 00:07:22,120 Speaker 1: for saying, like what what what? We don't just be 116 00:07:22,160 --> 00:07:24,720 Speaker 1: like orange juice is fine, coffee is fine, because if 117 00:07:24,720 --> 00:07:26,560 Speaker 1: you think about it, if a rained orange juice all 118 00:07:26,600 --> 00:07:29,440 Speaker 1: the time, you'd probably have the same impact. Would be 119 00:07:29,520 --> 00:07:32,160 Speaker 1: awesome about just like all the old cup out the 120 00:07:32,160 --> 00:07:37,720 Speaker 1: window each morning, I'd be like, oh, it's with pulp today. Um. 121 00:07:37,800 --> 00:07:40,800 Speaker 1: The problem with acid rain though, Josh, even though it 122 00:07:40,960 --> 00:07:45,240 Speaker 1: is has the acidity of a coffee or an orange juice, 123 00:07:45,800 --> 00:07:49,120 Speaker 1: it um can wreck small parts of an ecosystem. And 124 00:07:49,160 --> 00:07:51,760 Speaker 1: as we all know, if you wreck small parts of 125 00:07:51,760 --> 00:07:55,080 Speaker 1: an ecosystem, there's a domino effect that occurs that spreads 126 00:07:55,120 --> 00:07:58,760 Speaker 1: throughout an ecosystem. One of the most valuable things on 127 00:07:58,800 --> 00:08:02,800 Speaker 1: the planet is something like plankton. Yeah, plankton is high currents. 128 00:08:02,920 --> 00:08:05,320 Speaker 1: It's like honey buns in prison, but for the yeah, 129 00:08:05,520 --> 00:08:08,000 Speaker 1: you know pretty much. And when plankton, which is very 130 00:08:08,080 --> 00:08:12,800 Speaker 1: very sensitive to changes in pH um, especially when it 131 00:08:12,920 --> 00:08:18,320 Speaker 1: becomes more acidic, when plankton dies and small invertebrates die, 132 00:08:18,680 --> 00:08:22,920 Speaker 1: then yeah, it starves out the larger animals, fish and frogs, 133 00:08:23,600 --> 00:08:26,480 Speaker 1: and then we start to get hungry, especially the French 134 00:08:26,640 --> 00:08:29,880 Speaker 1: we frog legs e g. Acid rain is a huge 135 00:08:29,880 --> 00:08:34,000 Speaker 1: problem in France, that's right, And eventually it's just mass hysteria. 136 00:08:34,760 --> 00:08:38,160 Speaker 1: Pretty much got some dogs living together kimberally from different 137 00:08:38,160 --> 00:08:40,960 Speaker 1: strokes and up with green hair. That's right. Uh. There 138 00:08:40,960 --> 00:08:44,200 Speaker 1: are a couple of UM programs UM that monitor this 139 00:08:44,600 --> 00:08:48,760 Speaker 1: UH in the US, the National Atmospheric Deposition Program and 140 00:08:48,840 --> 00:08:52,240 Speaker 1: they handled the wet deposition and the Clean Air Status 141 00:08:52,280 --> 00:08:55,440 Speaker 1: and Trends Network. UM handled the dry And what they're 142 00:08:55,480 --> 00:08:59,040 Speaker 1: looking for is trying to determine the critical load, which 143 00:08:59,080 --> 00:09:04,160 Speaker 1: is how much an ecosystem can UM take before it 144 00:09:04,240 --> 00:09:08,240 Speaker 1: starts saying, man, I'm breaking down. You're killing me with 145 00:09:08,280 --> 00:09:13,240 Speaker 1: this stuff. UM. And the pH scale is determined by 146 00:09:13,640 --> 00:09:17,760 Speaker 1: UH the concentration of hydrogen ions right in a substance. 147 00:09:17,800 --> 00:09:21,400 Speaker 1: That's what makes it either UM acidic or basic. Right. 148 00:09:21,880 --> 00:09:25,479 Speaker 1: So what these programs are doing is measuring the concentration 149 00:09:25,520 --> 00:09:30,000 Speaker 1: of hydrogen ions to determine acidity. And they say, oh, well, 150 00:09:30,000 --> 00:09:33,760 Speaker 1: this is this is too much science. I would just 151 00:09:33,800 --> 00:09:36,280 Speaker 1: walk out and be like, look at this. This plankton 152 00:09:36,480 --> 00:09:39,160 Speaker 1: is not looking very healthy. This is acidic. I don't 153 00:09:39,160 --> 00:09:41,720 Speaker 1: even need to measure this stuff. You can just spot 154 00:09:41,880 --> 00:09:44,920 Speaker 1: unhappy plankton pretty much. It's not how you Once you 155 00:09:45,000 --> 00:09:47,439 Speaker 1: know what to look for, I'll teach you sometimes it's 156 00:09:47,480 --> 00:09:50,199 Speaker 1: not hard. When you've met happy plankton, your life will 157 00:09:50,200 --> 00:09:53,200 Speaker 1: never be the same. The difference is like night and day. 158 00:09:53,640 --> 00:10:00,040 Speaker 1: So UM surface waters are where acid rain is to 159 00:10:00,160 --> 00:10:04,040 Speaker 1: hit you most initially, um, precipitation, and you don't really 160 00:10:04,040 --> 00:10:05,880 Speaker 1: think about this. You think it, well, it rains in 161 00:10:05,920 --> 00:10:08,120 Speaker 1: a lake, what in a and in a river. What 162 00:10:08,200 --> 00:10:11,000 Speaker 1: it does is it rains on the ground. And although 163 00:10:11,520 --> 00:10:13,560 Speaker 1: sure it rains on the water surface, it's also going 164 00:10:13,600 --> 00:10:17,319 Speaker 1: to run through soil to get to water. Right. One 165 00:10:17,320 --> 00:10:19,800 Speaker 1: of the purposes of soil. One of the functions that 166 00:10:19,920 --> 00:10:25,840 Speaker 1: provides is um buffering uh water that percolates through it 167 00:10:25,960 --> 00:10:30,480 Speaker 1: toward groundwater, towards bodies of water. And what's buffering me? Well, 168 00:10:30,600 --> 00:10:36,000 Speaker 1: it has the ability to neutralize acids. Yeah, and then awesome, yeah, um, 169 00:10:36,040 --> 00:10:39,520 Speaker 1: I think it brings everything more toward purified water or 170 00:10:39,640 --> 00:10:45,080 Speaker 1: neutral pH right. Yeah, but I think specifically with a 171 00:10:45,120 --> 00:10:47,800 Speaker 1: lot of like the um, the minerals that are in 172 00:10:47,840 --> 00:10:52,840 Speaker 1: the soil, like say calcium, they counteract acidic um rain 173 00:10:53,320 --> 00:10:57,000 Speaker 1: acidic water to bring it more toward neutral right. The 174 00:10:57,040 --> 00:11:00,520 Speaker 1: problem is is when the soil's buffering capacity is a reloaded, 175 00:11:00,920 --> 00:11:03,440 Speaker 1: there's just too much for it to handle. A lot 176 00:11:03,480 --> 00:11:07,120 Speaker 1: of that unneutralized acid gets passed along into the body 177 00:11:07,160 --> 00:11:09,360 Speaker 1: of water, and then you start to have those big 178 00:11:09,400 --> 00:11:12,840 Speaker 1: problems with the little unhappy plankton. Yeah, it's almost like 179 00:11:12,880 --> 00:11:17,120 Speaker 1: a water filter that's past its date. You know, it 180 00:11:17,200 --> 00:11:20,480 Speaker 1: just can't filter anymore. Nice analogy, thank you. UM. So 181 00:11:20,559 --> 00:11:23,520 Speaker 1: we've talked about what happens where the French end up 182 00:11:23,520 --> 00:11:27,560 Speaker 1: with a lot of big problems in UM coastal areas. 183 00:11:28,200 --> 00:11:33,000 Speaker 1: Uh nitrogen, Remember we have UM what is it sulfuric 184 00:11:33,040 --> 00:11:39,400 Speaker 1: acid and what acid? Yeah, nitric acid. Okay, So nitric 185 00:11:39,440 --> 00:11:43,000 Speaker 1: acid is based on nitrogen. Nitrogen has a really interesting 186 00:11:43,040 --> 00:11:48,560 Speaker 1: impact on coastal waters where when it's deposited UM, it 187 00:11:48,640 --> 00:11:54,679 Speaker 1: supports algae blooms because algae love nitrogen. And when algae 188 00:11:54,720 --> 00:11:58,800 Speaker 1: blooms take place, algae starts to die eventually, and they 189 00:11:58,840 --> 00:12:05,240 Speaker 1: sustained bacteria, specifically aerobic bacteria that flourishes itself and sucks 190 00:12:05,320 --> 00:12:09,800 Speaker 1: up all the oxygen in the water, starving fish, shellfish, 191 00:12:10,040 --> 00:12:14,719 Speaker 1: um plants, and eventually like leading to at the very 192 00:12:14,800 --> 00:12:17,800 Speaker 1: least a strain, if not a collapse on coastal ecosystem. 193 00:12:18,000 --> 00:12:23,080 Speaker 1: So too much acid rain will increase algae. Increased algae 194 00:12:23,080 --> 00:12:26,600 Speaker 1: means increased dyeing algae, and increased dyeing algae means increased 195 00:12:26,600 --> 00:12:32,720 Speaker 1: bacteria and they rob fishes of their oxygen. That's a 196 00:12:32,760 --> 00:12:34,920 Speaker 1: domino effect. One of the things I love about acid 197 00:12:35,000 --> 00:12:39,160 Speaker 1: rain is just how elegantly understandable it is. It is 198 00:12:39,280 --> 00:12:44,680 Speaker 1: very basic and simple. I love it. It's not basic acidic. Um. 199 00:12:44,840 --> 00:12:47,160 Speaker 1: So this we're not done with the soil too, by 200 00:12:47,200 --> 00:12:51,640 Speaker 1: the way, in a in an addition to UM, I 201 00:12:52,000 --> 00:12:57,680 Speaker 1: guess decreasing its buffering capacity or overloading its buffering capacity. Um. 202 00:12:58,800 --> 00:13:04,400 Speaker 1: Acid rain has the terrible habit of drawing aluminum out 203 00:13:04,400 --> 00:13:07,040 Speaker 1: of the soil. Yeah, it's normally locked in the soil. 204 00:13:07,480 --> 00:13:09,920 Speaker 1: Acid rain draws it out, which means that tree roots 205 00:13:09,960 --> 00:13:12,880 Speaker 1: can suck it up, and that's poison to them. That's 206 00:13:12,880 --> 00:13:16,959 Speaker 1: a toxin. Yeah. And Sarah makes a good point here. 207 00:13:17,000 --> 00:13:20,240 Speaker 1: It's not like a it's not a situation where you're 208 00:13:20,240 --> 00:13:22,880 Speaker 1: gonna find a rainforest is leveled all of a sudden 209 00:13:23,160 --> 00:13:26,200 Speaker 1: because of acid rain, or you're gonna find a lake 210 00:13:26,679 --> 00:13:30,600 Speaker 1: or a river that looks nasty and decaying and disgusting 211 00:13:31,120 --> 00:13:34,520 Speaker 1: water might actually look cleaner. Yeah. And then ironic it is. 212 00:13:34,720 --> 00:13:37,880 Speaker 1: It's ironic and beautiful. And um, what it's gonna do 213 00:13:37,920 --> 00:13:41,120 Speaker 1: to your forest is it's gonna stunt its growth and 214 00:13:41,280 --> 00:13:45,120 Speaker 1: over time it's gonna have an effect. Yeah, like you're 215 00:13:45,120 --> 00:13:51,800 Speaker 1: gonna have bald trees. Um. Because in addition to this, 216 00:13:52,240 --> 00:13:54,840 Speaker 1: toxins coming out in the soil on low lying areas 217 00:13:54,920 --> 00:14:00,000 Speaker 1: from acid rain um, and it also degrading helpful minerals 218 00:14:00,040 --> 00:14:02,120 Speaker 1: like we said, like calcium and other things that trees 219 00:14:02,160 --> 00:14:08,400 Speaker 1: also used. Um. In higher elevations, that acid rain turns 220 00:14:08,480 --> 00:14:11,280 Speaker 1: into an acid fog. That is a did that's crazy 221 00:14:11,280 --> 00:14:13,320 Speaker 1: to me that that I'm going to say at this 222 00:14:13,400 --> 00:14:18,439 Speaker 1: time that is a great band name acid yeah. Uh. 223 00:14:18,440 --> 00:14:21,120 Speaker 1: But so just imagine like trees bathing in that all 224 00:14:21,200 --> 00:14:24,920 Speaker 1: the time, um, that that strips their leaves and basically 225 00:14:25,160 --> 00:14:28,600 Speaker 1: makes them chili. Yeah. And that's why when you see 226 00:14:29,040 --> 00:14:33,880 Speaker 1: mountains in the Appalachian Mountains that have bald peaks, it's 227 00:14:33,880 --> 00:14:37,120 Speaker 1: not because trees can't grow up there. They could grow 228 00:14:37,200 --> 00:14:40,400 Speaker 1: up there if they weren't sucking in and being surrounded 229 00:14:40,400 --> 00:14:45,040 Speaker 1: by acid clouds. That's nuts. Just it doesn't you have 230 00:14:45,080 --> 00:14:47,760 Speaker 1: to be raining, right, yeah, you know, it's just in 231 00:14:48,000 --> 00:14:51,800 Speaker 1: particulates in the air. Uh. And that that kind of 232 00:14:51,880 --> 00:14:56,520 Speaker 1: leads to how it affects us because we are not 233 00:14:56,720 --> 00:15:01,040 Speaker 1: nearly as sensitive to these kind of changes um with 234 00:15:01,120 --> 00:15:03,680 Speaker 1: acid that that acid rain brings. Right now, it's not 235 00:15:03,680 --> 00:15:06,720 Speaker 1: gonna burn. You know, you can swim in a lake, uh, 236 00:15:06,760 --> 00:15:10,600 Speaker 1: an acid lake and you will be fine. Um, but 237 00:15:11,240 --> 00:15:14,760 Speaker 1: an acidic lake, let's say, and yeah, because it's just 238 00:15:14,800 --> 00:15:17,840 Speaker 1: above battery acid. So you couldn't swim in a battery 239 00:15:17,840 --> 00:15:21,480 Speaker 1: acid like that. That's terrible. Um, But you could swim 240 00:15:21,520 --> 00:15:25,640 Speaker 1: in an acidic lake as far as acid rains concerned. Um, 241 00:15:25,680 --> 00:15:31,440 Speaker 1: the problem comes with that dry deposition. The UM sulfuric 242 00:15:31,640 --> 00:15:37,160 Speaker 1: and nitric ox or nitric acids combine UH in low 243 00:15:37,280 --> 00:15:45,080 Speaker 1: lying areas with ozone yeah, VOCs and create small which 244 00:15:45,160 --> 00:15:50,800 Speaker 1: is bad for your respiratory system ground level baby. Um. 245 00:15:50,840 --> 00:15:54,600 Speaker 1: It can also do things like if you've ever seen 246 00:15:54,640 --> 00:15:58,440 Speaker 1: an old building that is UH, or a monument that's 247 00:15:58,480 --> 00:16:02,880 Speaker 1: got these little smooth grooves that could be acid corrosion 248 00:16:03,320 --> 00:16:05,880 Speaker 1: for like years and years to wear away stone. It'll 249 00:16:06,600 --> 00:16:10,280 Speaker 1: It's no friend to your car paint job, that's sure, 250 00:16:10,480 --> 00:16:12,320 Speaker 1: which I mean if you're into your car, it's a 251 00:16:12,320 --> 00:16:16,200 Speaker 1: big deal. Yeah. That tree, sap, pollen, bird droppings, and 252 00:16:16,400 --> 00:16:20,640 Speaker 1: acid rain are the four enemies of your of your 253 00:16:20,720 --> 00:16:26,280 Speaker 1: auto paint. They're considered corrosive, environmental fallout, and friend of Mako. Yeah, 254 00:16:26,400 --> 00:16:32,640 Speaker 1: Micho loves that stuff. Um so, uh, the idea about 255 00:16:32,680 --> 00:16:37,359 Speaker 1: acid rain, consider this that stone statue you're just describing. 256 00:16:38,400 --> 00:16:41,320 Speaker 1: That takes a long time. A lot of orange juice 257 00:16:41,400 --> 00:16:43,640 Speaker 1: rain has to fall on that thing for it to 258 00:16:43,680 --> 00:16:48,400 Speaker 1: become pock marked and weathered prematurely, right, Um, and it's 259 00:16:48,440 --> 00:16:51,560 Speaker 1: had actually plenty of time to do that. What the 260 00:16:51,840 --> 00:16:56,120 Speaker 1: statue of Edward James almost you'd be like spinning image. 261 00:16:57,040 --> 00:17:03,000 Speaker 1: So sorry, um so the man you got me with that? 262 00:17:03,680 --> 00:17:06,480 Speaker 1: So cool? The reason the reason it's had a long 263 00:17:06,600 --> 00:17:09,000 Speaker 1: we've had a long time, or that that statue was 264 00:17:09,320 --> 00:17:11,680 Speaker 1: weathered over very long times because we've had acid rain 265 00:17:11,720 --> 00:17:13,600 Speaker 1: for quite some time, ever since the beginning of the 266 00:17:13,600 --> 00:17:16,320 Speaker 1: Industrial Revolution, they think pretty much because remember they thought 267 00:17:16,320 --> 00:17:18,400 Speaker 1: it was very localized problem. And the reason they thought 268 00:17:18,440 --> 00:17:22,320 Speaker 1: it was local was because it had such quick rapid effects. 269 00:17:23,200 --> 00:17:25,639 Speaker 1: But the acid rain, I don't know who who coined 270 00:17:25,640 --> 00:17:29,240 Speaker 1: the term acid fog, but acid rain was coined by 271 00:17:29,320 --> 00:17:34,200 Speaker 1: an Englishman named Robert Angus Smith back in eighteen seventy two. Yeah, 272 00:17:34,560 --> 00:17:37,119 Speaker 1: and it was the monuments that made him say, what 273 00:17:37,400 --> 00:17:40,080 Speaker 1: in the heck is going on here? And there weren't 274 00:17:40,080 --> 00:17:42,920 Speaker 1: a lot of people back then, like I was thinking 275 00:17:42,920 --> 00:17:44,399 Speaker 1: when I read this like, man, it would have been 276 00:17:44,400 --> 00:17:49,080 Speaker 1: great if during this boom of ingenuity and industrial revolution 277 00:17:49,600 --> 00:17:53,760 Speaker 1: there were just as many people concerned with the impact 278 00:17:53,800 --> 00:17:56,440 Speaker 1: it might have. But it just couldn't have worked that way. 279 00:17:56,520 --> 00:17:59,200 Speaker 1: It's almost like they just had to do their thing 280 00:17:59,359 --> 00:18:02,359 Speaker 1: and then leave us to figure out how to fix it, 281 00:18:02,440 --> 00:18:05,000 Speaker 1: how to clean up the mess sort of. I don't 282 00:18:05,040 --> 00:18:07,399 Speaker 1: know if those things to two things could have evolved. 283 00:18:08,640 --> 00:18:10,760 Speaker 1: So I think you're onto something. I mean, maybe we 284 00:18:10,800 --> 00:18:17,320 Speaker 1: wouldn't have um, I don't know, the iPhone. Maybe, who knows, 285 00:18:17,440 --> 00:18:20,800 Speaker 1: Maybe we would I don't know. Maybe we'd be better off, yeah, 286 00:18:20,960 --> 00:18:23,040 Speaker 1: a lot better off. Maybe we would have more stuff. 287 00:18:23,040 --> 00:18:25,600 Speaker 1: Maybe it would have changed the way of thinking rather 288 00:18:25,680 --> 00:18:28,439 Speaker 1: than just get get get, you know, it would have 289 00:18:28,440 --> 00:18:31,560 Speaker 1: been get. But also, how's this going to affect other people? 290 00:18:32,040 --> 00:18:39,560 Speaker 1: So Smith was a man alone. An early ecologist will say, yeah, 291 00:18:39,640 --> 00:18:41,919 Speaker 1: it's so good for him. Man, you've been coming up 292 00:18:41,920 --> 00:18:47,520 Speaker 1: with some great, like off the cuff, creative solutions. Well, 293 00:18:47,560 --> 00:18:49,680 Speaker 1: that's not a solution. If we had a time machine, 294 00:18:49,680 --> 00:18:52,720 Speaker 1: it would be okay, Yeah, the way back machines in 295 00:18:52,760 --> 00:18:59,080 Speaker 1: the shops. Uh. So scientists did determine um by what 296 00:18:59,160 --> 00:19:03,680 Speaker 1: the seventies nineteen seventies that acid rain was a problem, 297 00:19:03,760 --> 00:19:07,399 Speaker 1: and it was transboundary, it's not just local. And so 298 00:19:07,480 --> 00:19:12,160 Speaker 1: then in night thankfully the Acid Deposition Act, I said 299 00:19:12,200 --> 00:19:13,800 Speaker 1: you know what, we're gonna study this for ten years 300 00:19:14,640 --> 00:19:16,800 Speaker 1: and we're gonna see what's going on ten years later 301 00:19:16,800 --> 00:19:19,680 Speaker 1: in nineteen nine and they said, yep, that's a big problem. Yea, 302 00:19:20,200 --> 00:19:22,280 Speaker 1: So we need to do something about it, and they 303 00:19:22,320 --> 00:19:27,160 Speaker 1: did very quickly. Congress um took the already established Clean 304 00:19:27,200 --> 00:19:32,280 Speaker 1: Air Act and added UM sulfur dioxide and UH nitrous oxide, 305 00:19:32,320 --> 00:19:37,400 Speaker 1: nitrogen oxide right to the list of like most wanted 306 00:19:37,800 --> 00:19:43,600 Speaker 1: reduction people materials. And this was in with the Clean 307 00:19:43,720 --> 00:19:48,760 Speaker 1: Air Act and the Acid Rain program. So this is 308 00:19:48,800 --> 00:19:51,880 Speaker 1: when everything really starts to come into effect, right UM. 309 00:19:52,000 --> 00:19:56,119 Speaker 1: And it I guess at least as far as sulfur 310 00:19:56,160 --> 00:20:01,000 Speaker 1: dioxide emissions went, it was wildly successful. Compared to nine 311 00:20:01,240 --> 00:20:06,760 Speaker 1: eight levels in two thousand ten. The the sulfur dioxide 312 00:20:06,760 --> 00:20:12,800 Speaker 1: emissions have been reduced by that's good. That's astounding. That 313 00:20:13,000 --> 00:20:16,920 Speaker 1: is astounding because consider this, that's not from hitting this. 314 00:20:17,160 --> 00:20:22,919 Speaker 1: Since that's hitting we already got it back down to 315 00:20:26,000 --> 00:20:28,720 Speaker 1: seventeen years. That's amazing. And the way they did that 316 00:20:29,200 --> 00:20:31,600 Speaker 1: is through a cap and trade scheme. I kind of 317 00:20:31,640 --> 00:20:33,680 Speaker 1: like the old cap and trade. It makes a lot 318 00:20:33,720 --> 00:20:37,160 Speaker 1: of sense cap and trade, Josh. Basically what they say 319 00:20:37,280 --> 00:20:40,240 Speaker 1: is we're gonna set a cap for how much s 320 00:20:40,280 --> 00:20:45,399 Speaker 1: O two that your power plant can create. It's a limit, um, 321 00:20:45,440 --> 00:20:47,080 Speaker 1: but they set the cap, and they says, you know what, 322 00:20:47,080 --> 00:20:49,919 Speaker 1: you've got these allowances though, if you come under, you 323 00:20:50,000 --> 00:20:51,879 Speaker 1: get these credits and you can actually sell those to 324 00:20:51,960 --> 00:20:54,600 Speaker 1: other companies that are in need. And it just I 325 00:20:54,680 --> 00:20:56,199 Speaker 1: don't know, so I'm about it makes sense to me. 326 00:20:56,359 --> 00:20:58,879 Speaker 1: It makes a lot of sense. And then over time 327 00:20:59,320 --> 00:21:04,840 Speaker 1: you decrease the amount that that people are allowed to admit, 328 00:21:05,359 --> 00:21:08,120 Speaker 1: and when you're cutting it into these allowances, those allowances, 329 00:21:08,640 --> 00:21:14,520 Speaker 1: by by virtue of the scarcity of them, become more valuable. Yeah, 330 00:21:14,520 --> 00:21:16,840 Speaker 1: it really incentivizes you to do something about it for 331 00:21:16,920 --> 00:21:19,320 Speaker 1: your company exactly. So that worked really well for nitrous 332 00:21:19,359 --> 00:21:24,119 Speaker 1: oxide or for sodium sulfur dioxide. Man, what are we 333 00:21:24,160 --> 00:21:30,760 Speaker 1: even talking about here, um, And with nitrogen oxides, they 334 00:21:30,880 --> 00:21:33,760 Speaker 1: didn't institute a cap and trade until like two thousand three, 335 00:21:33,920 --> 00:21:36,320 Speaker 1: so it was lagging a little bit, but it too 336 00:21:36,400 --> 00:21:39,880 Speaker 1: is something of a success story. They um, they reduced 337 00:21:39,880 --> 00:21:43,639 Speaker 1: it from twenty seven million tons in nineteen eighty to 338 00:21:43,800 --> 00:21:46,480 Speaker 1: sixteen point three million tons in two thousand and eight. 339 00:21:47,280 --> 00:21:51,520 Speaker 1: That's pretty good. And so this has had a discernible 340 00:21:51,520 --> 00:21:58,120 Speaker 1: effect on the environment. UM. Apparently, Uh, let's see the 341 00:21:58,160 --> 00:22:01,760 Speaker 1: acidic likes. The number of acidic lakes throughout the country 342 00:22:02,600 --> 00:22:07,960 Speaker 1: have reduced dramatically. UM. There are seventy fewer acidic lakes 343 00:22:07,960 --> 00:22:12,360 Speaker 1: and streams in Wisconsin and Michigan than there were in UM. 344 00:22:12,480 --> 00:22:15,600 Speaker 1: A third of the bodies of water that were acidic 345 00:22:15,640 --> 00:22:18,480 Speaker 1: in the early nineties in the Adirondacks and the Northern 346 00:22:18,480 --> 00:22:23,400 Speaker 1: Appalachians are now not considered acidic at all. So there 347 00:22:23,400 --> 00:22:27,919 Speaker 1: have been like huge strides made other places there have 348 00:22:28,080 --> 00:22:30,480 Speaker 1: not been. And also you found this really good little 349 00:22:30,560 --> 00:22:32,840 Speaker 1: kind of overview about acid rain and what happened to 350 00:22:32,880 --> 00:22:36,400 Speaker 1: it by Nina Rostogi from Slate. That's whose stuff I'm 351 00:22:36,440 --> 00:22:39,040 Speaker 1: quoting right now. So there have been huge strides, but 352 00:22:39,480 --> 00:22:43,760 Speaker 1: there's still, like you said, originally a long way to go. Yeah. 353 00:22:43,840 --> 00:22:49,840 Speaker 1: The National Acidic Precipitation Assessment Program said that. Um. Another 354 00:22:50,119 --> 00:22:53,960 Speaker 1: another is what we need to hit to really restore 355 00:22:54,000 --> 00:22:58,280 Speaker 1: these ecosystems, And I think we're headed there. It sounds 356 00:22:58,320 --> 00:23:01,240 Speaker 1: like it like we'll check in in ten years and 357 00:23:01,280 --> 00:23:07,600 Speaker 1: follow up on this. M Who am I kidding? We could? 358 00:23:08,320 --> 00:23:12,400 Speaker 1: Well no, well, well well it'll be our comeback special. 359 00:23:13,280 --> 00:23:17,200 Speaker 1: Whatever happened to whatever happened to acid? Right? Great? Um, 360 00:23:17,240 --> 00:23:19,919 Speaker 1: but Chuck, I think that this is a really valuable lesson. 361 00:23:20,720 --> 00:23:28,880 Speaker 1: If you have a non polarized international initiative to take 362 00:23:28,920 --> 00:23:33,159 Speaker 1: care of a problem, and you can shout down business 363 00:23:33,160 --> 00:23:35,160 Speaker 1: interests and just say no, this is what you're doing 364 00:23:35,200 --> 00:23:38,760 Speaker 1: and here's how you're gonna do it. Um, you can 365 00:23:39,000 --> 00:23:41,639 Speaker 1: make things happen. Yeah. I guess no one was saying 366 00:23:42,280 --> 00:23:46,199 Speaker 1: that should rain doesn't exist is really not bad. It 367 00:23:46,240 --> 00:23:49,040 Speaker 1: was pretty much nonpolarizing except for big business. And also 368 00:23:49,240 --> 00:23:51,959 Speaker 1: where any jobs lost by this cap and trade scheme? 369 00:23:52,560 --> 00:23:55,320 Speaker 1: Was industry hurt by this cap and trade scheme? I 370 00:23:55,320 --> 00:23:58,520 Speaker 1: would wage, you're probably not I would wage or not. 371 00:23:58,840 --> 00:24:00,760 Speaker 1: But they're still in business. They're just doing it with 372 00:24:01,040 --> 00:24:04,720 Speaker 1: clean coal and wet scrubbers and yeah, all that all 373 00:24:04,720 --> 00:24:07,760 Speaker 1: that good stuff. Yeah, it's interesting. And I'm not even 374 00:24:07,760 --> 00:24:11,160 Speaker 1: an environmentalist. I hate the environment. I'm just fascinated by 375 00:24:11,200 --> 00:24:14,119 Speaker 1: this stuff that's not true. Well, if you want to 376 00:24:14,200 --> 00:24:17,399 Speaker 1: learn more about acid rain or acid fog. You can 377 00:24:17,440 --> 00:24:19,520 Speaker 1: type either of those words into the search bar at 378 00:24:19,520 --> 00:24:21,800 Speaker 1: how stuff works dot com and that will bring up 379 00:24:21,840 --> 00:24:25,879 Speaker 1: this very interesting article by Sarah Dowdy. And uh, I said, um, 380 00:24:26,000 --> 00:24:32,359 Speaker 1: acid fog, which means the time for listener mail before 381 00:24:32,400 --> 00:24:34,600 Speaker 1: listener mail quickly. We are going to Comic Con this 382 00:24:34,680 --> 00:24:39,320 Speaker 1: year for the first time. Yeah, like we're like presenting 383 00:24:39,600 --> 00:24:41,800 Speaker 1: at comic Con.

Yeah, and it may or may 392 00:25:03,200 --> 00:25:07,359 Speaker 1: not our presentation may or may not include certain other 393 00:25:07,800 --> 00:25:10,080 Speaker 1: I don't think we should go any further. You're gonna 394 00:25:10,080 --> 00:25:12,679 Speaker 1: get us in trouble. Well, we're trying to land some 395 00:25:12,680 --> 00:25:17,119 Speaker 1: some whales. Okay, I'm gonna call this m I t 396 00:25:17,320 --> 00:25:20,480 Speaker 1: nerd alert. I got a very nerdy email from an M. 397 00:25:20,480 --> 00:25:23,080 Speaker 1: I T student, and I teased her and said, I'm 398 00:25:23,080 --> 00:25:24,480 Speaker 1: gonna read this on the air and make fun of you. 399 00:25:24,680 --> 00:25:26,360 Speaker 1: Is that okay? And she went, oh yeah, And here's 400 00:25:26,359 --> 00:25:27,960 Speaker 1: some other stuff you can make fun of me about. 401 00:25:28,880 --> 00:25:31,359 Speaker 1: Um Hi, Josh and Chuck and Jerry. I love your 402 00:25:31,359 --> 00:25:33,840 Speaker 1: recent episode on how language evolved. But as an m 403 00:25:33,840 --> 00:25:37,159 Speaker 1: I T. Senior graduating in a month which is probably 404 00:25:37,160 --> 00:25:40,000 Speaker 1: like right now, actually, um, I felt it my duty 405 00:25:40,000 --> 00:25:42,399 Speaker 1: to make a very important correction to your intro. We 406 00:25:42,440 --> 00:25:45,040 Speaker 1: are called the m I T Engineers, not the m 407 00:25:45,040 --> 00:25:49,240 Speaker 1: I T eggheads. I think I called a meg heads. Indeed, 408 00:25:49,240 --> 00:25:51,800 Speaker 1: our unofficial school song is the m I T. Engineer's 409 00:25:51,880 --> 00:25:55,240 Speaker 1: Drinking Song, which includes many nerdy jokes, some of the 410 00:25:55,280 --> 00:25:59,520 Speaker 1: expense of that small liberal arts school up the river Harvard. Additionally, 411 00:25:59,560 --> 00:26:03,199 Speaker 1: our mask dot is Tim the beaver, Tim being M 412 00:26:03,200 --> 00:26:08,240 Speaker 1: I T spelled backwards. It's so glamor because beaver's are 413 00:26:08,320 --> 00:26:12,120 Speaker 1: nature's engineers. In fact, every class has a special ring 414 00:26:12,200 --> 00:26:15,560 Speaker 1: called the brass Rat, which depicts a beaver on a bezel. 415 00:26:16,800 --> 00:26:20,040 Speaker 1: Be eazy e l what is that? See, I'm so dumb. 416 00:26:20,040 --> 00:26:21,600 Speaker 1: I don't even know what a bezel. We would not 417 00:26:21,720 --> 00:26:24,960 Speaker 1: make it an M I T I suppose supposedly it's 418 00:26:24,960 --> 00:26:28,000 Speaker 1: one of the most recognizable rings in the world. Man 419 00:26:28,200 --> 00:26:30,440 Speaker 1: um I started listening to the podcast during long, long 420 00:26:30,480 --> 00:26:32,840 Speaker 1: hours and lab and grateful and I'm grateful to you 421 00:26:32,840 --> 00:26:35,760 Speaker 1: guys for entertaining me during my past four years.

Thanks 446 00:28:05,960 --> 00:28:07,600 Speaker 1: a lot, Laura. That was a good one, And I 447 00:28:07,640 --> 00:28:09,480 Speaker 1: have one for you. You want to hear an engineer 448 00:28:09,560 --> 00:28:11,679 Speaker 1: joke that my dad, who was an engineer, taught me 449 00:28:11,760 --> 00:28:14,520 Speaker 1: a long time ago from the Herbal Elvis himself. Let's 450 00:28:14,520 --> 00:28:16,359 Speaker 1: hear it takes a minute. When will you bear with me? 451 00:28:16,800 --> 00:28:20,000 Speaker 1: So an engineer, a priest, and a doctor are all 452 00:28:20,040 --> 00:28:23,640 Speaker 1: playing golf one day, and um, ahead of them are 453 00:28:23,680 --> 00:28:27,720 Speaker 1: these guys and they stink they're hitting there, they're driving 454 00:28:27,720 --> 00:28:31,679 Speaker 1: in like the opposite direction of the whole. They're just 455 00:28:32,080 --> 00:28:35,680 Speaker 1: really terrible at the game of golf. So the beer 456 00:28:35,680 --> 00:28:38,560 Speaker 1: guy comes around on his cart and um, the priest 457 00:28:38,720 --> 00:28:40,840 Speaker 1: is like, do you have any idea. Who these guys 458 00:28:40,840 --> 00:28:43,440 Speaker 1: are there? They I've never seen anybody play golf this badly. 459 00:28:43,480 --> 00:28:47,080 Speaker 1: And the beer guy goes, oh, those are three firefighters, 460 00:28:47,240 --> 00:28:50,840 Speaker 1: and um, they put out the clubhouse when it caught fire. 461 00:28:50,920 --> 00:28:52,880 Speaker 1: But they all lost their sight in this fire. So 462 00:28:52,960 --> 00:28:55,680 Speaker 1: we let them play whenever they want. And then priestly 463 00:28:56,160 --> 00:28:58,200 Speaker 1: takes a step back and puts his heart on his 464 00:28:58,440 --> 00:29:00,240 Speaker 1: or his hand on his heart, and he goes, Oh, 465 00:29:00,400 --> 00:29:03,240 Speaker 1: Faith and Begora, just give me their names.
