Der Umwelt-Henker

I don't know how it works, but I've known it for a long time. I drive a lot of cars, you know, I sometimes drive to work because I have to brush my teeth. Then sometimes, when I don't get to take my own to-go-becher to take me to a pub or a coffee pub, we know it's actually better now, right? Less cars are driving, less garbage is being produced, that would be good. Welcome to the fight that I have with my wife almost every day. We all know that, but I'm a really used to it. I sometimes can't do it either. I really like to drive cars, it's really bad. I could drive public, theoretically, to work here, but I have to get to work now. No, I don't want to do that. What did your wife say? She gave up. Really? Yes, she gave up. She gave up, she knows what to do, and it doesn't matter anymore. I have a bad conscience, but up to a certain point I can also show off quite well. Yes, I think we should all think about our habits. You can also change habits, Christian, even if you're 35 years old. That's a little hint on the edge. But I don't think you have to make a bad conscience all the time. Except, you know, Thomas Mitchley. Because on his account, there's just nothing less than the invention of the fucking ozone hole. Nice. Yeah, the antarctis, thanks. And you too, because we have a nice DGD story. We are Christian Alt and Anna Büder. And we are telling you in this podcast the epic fails of human history and today the really incredible fail of Thomas Mitchley. I have already said that he can be the biggest environmentalist in the world at all times in history, without question. The inventor of Friday's preheat room, just. God, but hey. So the ozone hole, I already mentioned, stands on his account. But it's not just one fail that he has achieved on the cost of the environment. No, there were two at once and both contributed to massive environmental pollution. Cool. Thomas Mitchley Jr. is an American, 1889 and I think at the birth date you can already imagine what kind of time the big one is. So, as a young man, he actually lives in a time when almost everything seems possible. In 1918, the first world war ends, the USA is on the winner's side, the gold in the 20s are unleashed. And Mitchley is there really in his best years, yes, that's just the beginning of 30s. So I think I would have liked to be in the 20s, too. Definitely. Or especially in the USA. Well, you have such a small pandemic at the start, unfortunately, so the Spanish flu is a bit of a mess, but otherwise, if you are white, I think you have a good time in the 20s. Exactly. I also think that if you live in New York, it's a nice start. Exactly. If you have a bit of money, then I think that's a good time. Then it's a good time. If you are poor or black, not so cool. Then not so good. But Mitchley is white and comes from good relationships, so he can do that really nicely. So maybe the 20s a little bit to draw a picture, the economy, the blood, art and culture also. So I imagine that before, that everyone else in beautiful, masked clothes and send clothes out of satin and silk, dancing in the evening, or something like that. And that's why I think it was always, I think it was awesome, it was vibrating and the big cities are really lit up again. But it's also the time of the inventors, yes. I have a list of very funny things that were invented in the 20s. Or surprising things, I think. In 1920, a policeman from Detroit was invented, the Ampel. Awesome. A policeman from Detroit. I think it's so funny. So I don't know in what situation he had the idea, but you can imagine it. Probably. Here on the roadside. Yes, or he probably has to go through people and thinks, hey, I can do my job. Must go differently. Just make a stop sign that changes. Yes, exactly. In 1920, the phoenix was invented, so really a good thing against ... So you don't use phoenix. We talked about it before, always with wet hair, even in winter to work. Always in the car. Yes, because when you get in the car. 1921 was invented by a medical student from California, the lying detector. Ah yes. Very important. And then also something like insulin, the TV, the electric razor. Really things that we use to this day. The radio. The radio, of course. Of course. Now we have somehow such a cool phoenix from ... From Dyson. From Dyson, exactly. The one with the hole in the middle. Yes. They look a bit different, but in principle, this product hasn't actually developed since. Can I say something about this Dyson phoenix? Yes. Have we booked a advertising blog or is it now on your own? On my own. My wife wanted to have it for years, she bought it now. And? And it's really cool. It's really cool. It's just really cool phoenix. Yes. Yes, I think it looks so nice on its own. Yes. I found it at Lidl, which is on it by Christine Aguilera. I now have it pink. It's awesome. It's hard. Come on over. Come on over. Come on over. Baby. Yes. Every morning. Thomas Mitchell is definitely also an inventor, and he works in a real Tüftler family. So supposedly one of his English ancestors was involved in the development of the steam machine with James Watt . Awesome. So not only a bit of an inventor, but really one of the most important discoveries of the industrial age. By the way, the grandfather's mother, James Emerson, was in the middle of the 19th century in the Californian wood industry. He developed very smooth profiles, so probably also super important for wood production. And his father, Thomas Mishley Sr., had an idea workshop for car tires and reported dozens of patents for steel wheels. So you mess up with your mother, when you're in such a family, somehow big, you can't do anything else than somehow invent things. Yes, Mishley Jr. does that a lot, so as a young man, he rubs around. He studies mechanical construction at the renowned Cornell University, is then later in an IT company, and in the end, at Delco Electronics. This is such a company that produces electronics for the automobile industry, they will also be taken over by General Motors later. And the automobile industry can't be that old at that time, right? Henry Ford somehow finds in the decades, I think, the mass production of automobiles. And from that point on, it just starts right away. Exactly. So that's also in the 1920s, that the automobile industry is very popular, and then probably also such a company, because Delco Electronics is suddenly working on contracts, probably we don't even know where. But for Mishley, it's great that he finds 24/7 on the thing, so there are voices of employees who say, "10 cases per minute has the man, 9 are obstruces and the 10th is awesome." But I mean, there's still one great accident in the minute. Yes, great. That's even more than I have in 10 years. Thomas Mishley must have found the peanut butter nutella sandwich or something like that so small. Yes, yes, that's true. In everyday life. Then there would be one more time to answer for it, so that turtles can circulate in the sea. He would have found a toilet paper hanging in the front to clean it up. Exactly. I mean, such things. Just a lot of brilliant ideas. But 9 of them were obstruces, for example to tap nails into your foot when it's snowing outside. Yes. That was stupid. Yes, that wasn't his best idea, but you can sometimes find crap. But he was supposed to be a funny guy, so to say, his friends and employees say that he is always funny and that he has found a lot of crap. That's definitely a kind of creativity. Yes, definitely. Which can definitely be really funny. But he already has the desire to give something to the person. So he doesn't just want to tap nails into his shoe, but he wants to do something that remains and in the ideal case also earn a bit of money with it. And with that he also fits great in the USA at the time, in the 20s, because here too it is so that innovations are asked. Yes, you want to be faster than the Europeans, you want to show who the boss is more or less. Every patent that is signed in the USA is such a small success, such a small thing. We have shown it to the others again. That's the mindset at the time and that fits with his passion. Perfect. Now it's like that, yes, innovations are always nice and good. You get a solution of a problem often a step closer, but often things are still not perfect yet. Even if you have put in a lot of work already, you have to look at some things again twice. And Michel will actually have two inventions in his career, on his desk more or less have. Which he should improve, which he should check and twice he will fail really hard. Example one, the combustion engine. So we have already said, car industry is the absolute blooming time. In 1916, Thomas Schmitzchli gets the contract from his boss, so he works with this film Delco. Please find a solution for the clump in engines. I don't know if you have it in your ears now, so to speak. Yes, I only know it from old tractors that have such a curve in front of them. If you want to look at such an old tractor, you do it like this, then it runs all the time. There's a lot of black rust in the back, just that comes out of the exhaust. You think, this thing crept, but at some point it starts. Yes, full. So this engine hits and comes from the cylinder head, which just doesn't run around. You can explain that. I had to, I think I had three or four YouTube explain videos to understand what happens there. You can explain it exactly. I'll try it now. In a combustion engine. I'll look back. I'll look back. In a combustion engine it is so that the engine is driven by a target explosion. So you spray a sealed gas into the engine room, this is then powered by the ignition core and then practically the piston goes down, drives the drivetrain on, then hits it up again, where there is another thing and practically this piston is sealed, this gasoline gas mixture, which then comes out of the engine room, that then creates energy that drives the engine and so on and so forth. Right. And if you have a four-cylinder or a six-cylinder, then you just have six or four coupes. So I have no idea if that's right or not, but I'll tell you, yes, that's right. Just a man always had such a engine. Or a man-made engine. So in the YouTube video I watched, where there was such an animation, it looked like this. Yes. Because my solution would have been, I just read it exactly what I have in my script. Yes, perfect. Okay, watch out. At the right combustion there are two ignitions in the combustion engine room, one on the ignition core and through the combustion pressure and through the temperature another uncontrolled ignition. Therefore there is a second parallel combustion in the cylinder cylinder and when the two ignitions meet on each other, there is a pressure wave with high frequency and they make the pengarouche. Oh, right. I actually only mentioned the normal combustion, right? Yes. So that's the uncontrolled one. The uncontrolled one. I don't want to have any more questions about it, because I really can't read more than that. It's bad. We are stuck in a role of a man-woman in the 1920s, but no engines are interested in me. I can't do anything. I can turn it and use it as I want. The problem with the uncontrolled combustion or with the valves in the engine is that many parts can break. The engines don't break at all, they break quickly. It's just bad for the automotive industry and that's why cars are even more expensive. Many people can't afford it, they can't afford the whole repair shop. It's terrible if you have to exchange the engine for all three years. Although cars are already quite widespread at this time, it could still work better. Michel is not the best person for this job, because he is not a chemist now. He has to understand a little more about what's going on there in the engine room. Because of the piston things and what's going on there. He has to understand more about the fuel mix and so on. It's probably about that. He finds that very quickly. He is a machine builder, but he is also a tifter, so he puts himself on and he likes the challenge. That's how he quickly finds out what the problem is and that's the fuel mix that comes in there. It doesn't burn evenly, that means he has to somehow rebuild it. He has to shake new things together and find a new cocktail that he drinks in the engine. And now his researcher is awake. He is supposed to have slept in his laboratory for some time on a field bed. He's over night there and is supposed to have tried out over 33,000 combinations of chemical mixes. It was really absurd, I imagine it in the form of reaction glasses and then explode or something. And he has hair that is already standing up to the mountain and always had rust in his face and so on. It must have been something like that, because he seems to be really stuck in there. It's just his world. He lives in this laboratory and just wants to find these components, how these valves are removed. He tries it, for example, with ethanol, alcohol, that would even work. The problem is there, then it would be much too expensive, because you need a huge amount of ethanol. So even if you think you have found the solution, then it's still not like you can say that it's the right solution for a wide market. That means you have to keep trying and keep trying and keep trying. Other substances that smell too much, he also finds that out. Apparently there is an anecdote that he smells the megamessy with substances around him. And he should have been sent seven months by his wife to a cellar to sleep. Because he always flutters when he gets out of work. Then he sleeps next to the emergency stop. Come on, get out of here. How long has this experiment been going on? It seems that it will take around five years. As I said, he will be sent off to his boss in 1916. And on December 3, 1921, Thomas Mitchley finally has the solution. After all his experiments, he finally has a breakthrough. One has to say that the first world war is also between them. That's why it probably takes five years. But he probably continues with short interruptions. He is probably also completely slow in the head because he always has to sleep in the cellar. Yes, you get annoyed. And to be honest, he's probably breathing slowly. Like I've met him now, let me tell you, we'll get to that in a moment. But like I've met Thomas Mitchley, I think he did everything without gloves or without a protective mask. That's enough. No problem. So on December 3, 1921, he has the miracle and the miracle is called tetraethylblei. At the last word, you already notice that it's not so good. There's the word "blei" in it. But it is a colorless, which is also good, almost tasteless liquid. A combination of carbon, hydrogen and justblei. And that actually works as an anti-cloth agent. Because when the combustion of carbon-hydrogen in the engine, a discolored chain reaction happens. And that's how it's going to work. Now I understand everything. Yes, me too, finally. Well, in any case, it's practically at this tetraethylblei that you only need a small amount of it. So it's kind of cheap, even if you need a lot. And that's good. It's actually the breakthrough for Mitchley. It locks the thick coal. And of course finally recognition. For the discovery, he even receives a medal from the American Chemistry Society. A William H. Nickles Medal. It's so very prestigious. So it doesn't take long until the world public becomes aware of him. And somehow everyone understands that he really has a problem with it. It's probably also a great invention. For the time being. The cars are running around. Yes, I thought so too. Probably people thought it was cool back then. Now we have the solution for everything. But what I didn't know until the research that you already knew exactly how dangerous blei is. Ah! Yes! So the people are like "Ah! Tetraethylblei!" No matter! Okay. So you know exactly, that was the burning of blei. Highly poisonous products are produced. Or that blei itself is also simply so dangerous. But this nut that you have. It was so big that you just bled it out. I read something about blei years ago. It's from a best seller from 15 years ago or so. And they took statistics together. And just took interesting guidelines from the statistics. Okay. And one of them is that if you take the use of blei and correlate it with the criminal statistics, you notice a very clear connection. So because people have simply become dumb through blei and violence. So at least it is the main connection. Because blei was also in the pipes, blei was in the gasoline and so on and so forth. Everything that we somehow took as a media from this time. How people think about each other. They were all on blei. It really is like an alien society. Which is controlled by... We have been down from the fuel for 30 years or so. Yes, luckily. It's actually like that. In the early years, 1922, when the first plans for production in the state were created. The production of this new fuel. There are super many voices that warn. For example, a German scientist called Charles Klaus. He actually warned that several colleagues would have changed. Even Stanford and Yale professors and scientists say, "Hey, pay attention to what you're doing. It's blei, but all of these voices will be agurated." It's really cool. Ignored or did the car industry have just their fingers in the game? Good. Most likely. So I mean, if the big money is locked, then it's probably the most powerful one. Definitely. So despite all warnings, the largest production went to the early 20s in the state. Because of money, very likely. But there are also quick problems. Okay, I'm not allowed to laugh. Sorry, excuse me. But I know what's coming. In the factory of DuPont in New Jersey, a worker died in autumn 1923. Again, three people died in 1924 and four people died in 1925. And that all depends on the production of blei together. So it's not a joke. It's really crazy. In one of the factories of Standard Oil in Bayway, New Jersey, there are also five workers dying. 44 people have to go to the hospital for this production. It's really stupid how fast this is going. How fast blei people are poisoned. I mean, it's just like that. Probably they just announced, "People, we have the solution." And the people in the factories are suffering immediately. They will be delivered, roughly. But of course the debate is so important. So the public gets questions from the people. He and his fellow workers agree that blei is dangerous. They can't argue about it. But only in the pure form. But we mix it up. And in the end, what we have, the product that we collect, that's great. You can bathe in it. No problem at all. And he also has a similar idea. To make a small image campaign. To prove to everyone once and for all that Tetra ethylblei, what he produced, that it's not poisonous, he has a really stupid idea. It's October 1924. So only three years after he finished Tetra ethylblei. And now it's just in the big production. Mitschle has invited some journalists to demonstrate something really cool. I imagine that now immediately that he was on such a big stage, spotting him, washing his hands in front of him, or picking up a canister with Tetra ethylblei. And in front of a collected team, he actually does the following. He takes this canister or this vessel and picks up Tetra ethylblei over his hands and washes himself with it. So I'm really enjoying the photo. He rubs it in like this. And he says, "Hey, look, nothing happens to me. I'm fine. No problem at all." He also says, "Every day he could do that without having to face health problems." Of course. You can't tell me that he believes in it himself. Well, I don't think so. I think his idea was bigger than he himself. He wanted to point out something and thought, "Okay, I'm sure I'm lucky again." He actually convinced the people. I mean, it was a presentation that the people had already shared, or at least you can't imagine that someone who knows that it's poisonous is doing something like that. That's why people believe in him. Mitschle himself did it, but in fact, with the following of a constant poison, to fight. Come on! Surprise! But in fact, he managed to keep it secret from the public. He survived this constant poison. He stayed at home for a few months or something. Yes, Thomas Mitschle, who just made this amazing presentation, said, "Oh, it's hard to reach right now." Yes, the night is just sabbatical. His wife says, "Sorry, the cellar is ringing." He wrote the lyrics for his first album. He had to concentrate a bit. He also wanted to do a bit of "Maternity Leaf" right now. I think there are a lot of people who think so. The symptoms of the constant poison are not without it. Of course, headache, memory loss. That's probably what you mean. The constant poison of the generation. Something happens in the head, hallucinations, crickets in the hands and feet. It really affects the constant poison. And you can also die from it. On the contrary, Mitschle has also been able to come in contact with his product afterwards. He also learned a bit from it. But on the outside, he still makes another cutamine. For example, they have the idea of ​​Tetra ethylblei as ethyl, so that the name doesn't scream "gift." That's how it's always called. There are also advertising posters, where a father sits with his son in the car. Then it says "ethyl." And then the father says, "I can drive really fast now. I can overtake them all." Because we are ethyl tankers. Our engine is crazy. They really talk about families. The middle of society should be ethyl tankers. And of course, it is also a fuel that everyone can afford. And because of that, more people can afford a car. Now they can afford a car. So it is also a chain of... Well, so in this moment there is an unfair agreement. I know that you are old Christian, have you ever thought of the Roman Empire? Today you don't know. Then I will come in. Did you know that blei was already in the Roman Empire? You already thought about it. Yes, they had a pipe from blei, right? Yes, exactly. They actually had blei pipe. It was also very popular material for other household items, war equipment, as you said, drinking water pipe. But it was also used in recipes for wine production. So they actually purified it in their wine. I don't know. Blei sugar, blei acetate. Oh, wait. There were probably archaeological studies of the skeletons that found out that the Roman skeletons compared to the skeletons from the time of the Iron have increased 400 times the size of blei. So that's also how you said before, that in the 20s and 30s everyone was in a fiber dream. There are a few things that are explained about the Roman Empire. I bet that it is also said about our clothes. When it's about things like microplastic. Look how stupid they are. How they put this stuff in. Something like that for a full idiot. No wonder that there was Donald Trump. So in the 20s the invention of Thomas Mitchley is booming. We know today that it is a huge failure. But because one failure for a Thomas Mitchley is not enough, you still remember the second failure. You still remember the second failure. That's also a failure that Thomas Mitchley actually has to answer. That's the protective part of this podcast, right, Thomas Mitchley? It's really one of the patterns that Darwin likes. Thomas Mitchley works at Delco, which are bought by General Motors. And that also belongs to a cooling system. Frigidaire. A cool machine, but also a normal household cooling system. For the normal household needs. And there he will soon get an order from his boss. And he is supposed to create a dangerous cold medium. With the first cooling systems it is like this. Cold mediums like chloramethane or ammonia or also sulfur oxide. So gases were used as a cold medium. Now you have to be a chemist to understand that these are very dangerous chemicals, very poisonous. When a little bit of gas comes out, it is highly poisonous. So there you can explode the entire house. What ever. The idea to live with a family, to have a fridge with ammonia in it, is completely crazy. That is, if there was just a small leak somewhere in the fridge, then it could end for people, what actually happened. In some communities in the USA, the quote "dead gas boxes" were actually forbidden in some communities of the USA. And you understand why. And they were probably also with bleach in it. They were probably also with bleach in it. Yes, so that you can touch a lot of things. It is definitely, you don't want to be at home now. Mischle has his call now. He is a well-known, outstanding inventor, national hero in that sense. And he wants to take on this problem now. And the story goes like this. Well, the rumor is that he only needed three days to find the solution for this problem with his team. Namely, FCKW gas. FCKW, also coal hydrogen, with which hydrogen atoms are replaced by chlorine or fluoride. FCKW gas has been around for a long time. There are ancestors, they were produced at the end of the 19th century, but synthesized in 1929 through Mischle. And I don't know exactly which testing methods there were back then, or maybe there weren't. But then they were really fast. Because in the early 1930s the industrial production began, the industrial FCKW production. Where millions of refrigerated climate systems, cooling devices, refrigerators, also as fire extinguishers and so it was taken. In spray cans it comes before. That's what you actually recognize today. FCKW gas is everywhere. Back then you didn't know, you have to take the protection with you. You didn't have to imagine that FCKW could create such a big global danger. But you can also be proactive, probably thought of a way to participate. And also here, not only to let people come to a stupid thought, that FCKW could be dangerous or poisonous or anything else. He proved to the public again on an old-fashioned way, per image campaign, that it's all tippy-toppy what he thought of there. In 1930 he once again introduced himself to the colleagues of the American Chemical Society on stage and just inhaled several liters of FCKW gas. You have to imagine, he takes a minute or so. And then he has a fire in front of him and he puffs it out to show that it doesn't burn. He wants to show that it's not harmless for me. I can breathe it alone without any problems. But it's also incurable. That was the biggest fear for the other refrigerators. Just like children today on the school floor on gas. Yes, children. Didn't we do that in the studio before we had a party here? I don't know. I just read somewhere that even in Germany, in the USA, of course, there are small potatoes with gas in them. That you can get rid of them if you're 12 or 11. Okay, thank you. New thing. Three years later. Bye. Ah, well, in 1937 apparently everyone has a second U.S. private household, an FCKW fridge, or a fridge in the FCKW gas, the fridge. Of course, it's a milestone. Of course, it's a huge invention. You can suddenly store food for a long time at home. Meat, baby food, vaccines, if you think about industrial refrigerators. Everything can be cooled reliably. It's an incredible medical revolution. Also, what for a milestone? Of course, a connection with Bly in Benzin where you say, "Okay, I don't only have a freezer, but I can also just drive the factory somewhere in Detroit down to Arkansas or something like that." You know, the routes that anyone can do with a functional freezer chain. That's true. I would have liked to run a parallel world and see what it would be if Mitchell didn't find it all. Because who knows? Something else had to be discovered. But, of course, mobility would never have come so far in the 20s, 30s and 40s. Or differently, who knows? Exactly. I find it always interesting to do such a thought experiment. He really did a great job. He also got high-ranking chemistry, drawing and honorary doctor title. In 1944, he became president of the American Chemical Society, then even changed. In fact, he is the highest-ranked chemist in the USA as actually a machine builder, which is also quite funny. At the time of his life, he was perfect for Thomas Mitchell. He is highly-ranked and he is rich. Of course, everything is great. And with this reputation, he dies. Basically, he goes to the grave in faith. Actually, in the knowledge that he has found something high-ranking, but in the belief that the world still feels for him. On November 2nd, 1944, he dies. That's crazy. He dies in 55 years. Yes, that's right. At the end of his life, he suffers from childhood injury. So he is stuck in a bed. And the way he dies, in any case, Thomas Mitchell is right, I would say. Because he has such an injury, he can no longer move properly, but he builds himself a kind of rope pull to set himself up in the bed and so on. And at some point, you find him strangled in his own rope pull. You don't know if it was an accident or an accident, but maybe it was just an accident. But basically, he ends up in his own invention at the end. That's kind of fitting for Thomas Mitchell. He is now unfortunately dead. But we still jump into the 1950s to a certain Claire Patterson. He is a farmer from Iowa. He is a geologist and he wants to find out in his doctor's work how old the earth is, so determine the earth age. And for that, he wants to take stone samples. So he boasts with such a fat drill, always really deep stone masses and then looks at the rings of the stone samples and examine them. And whenever he has taken these stone samples, they last for a long time. That annoys him, because he can't drive his research ahead. So he tries to get around and tries to put the samples directly after he has drilled them out. So to pack it in a vacuum or at least close the airtight. And you can see that the continuous cleaning is not so great when he does it. So if he does it directly after drilling in a plastic bag or so. That means, for him, the "blei", which is in my stone samples, always has to come out of the air. Patterson is looking for traces. He brings iceberg cores from Greenland, Austria and Arktis with him and reconstructs the "blei" concentration layer by layer. So you can read in which years the "blei" concentration is included in this ice. And the discovery is actually, before 1923, there was almost no "blei" in the atmosphere. What was 1923? Let's go back a bit. Thomas Mitzschlid, our honored doctor, our chemistry man of the U.S.A. and A. has found Tetra ethylblei, the anti-cloth agent. The science is so cool that he can say it exactly like that. But how cool is that? He just grazed the murder weapon. But with an iceberg, how cool? Super cool. So it is clear that "blei" is in our air. "blei" is poisoned by us, it is everywhere. We have to listen to this. Since the mid-1970s, the "blei" content was returned to Pkw forces. In 1986, it was finally banned in the U.S.A. and in 1988, also here in Germany. I think it's really quite long actually. It's almost 20 years since it was allowed to run like this. But I still remember it. I was born in 1988, but this "blei" free. The long time it was still standing there, because it wasn't independent. Yes, that's a word that you just know when you grew up at that time. By the way, it wasn't banned in terms of health. Not only, but also in terms of the degree. It is actually so that you happily found another Pkw catalyst in parallel. I don't think that would have been the case. Probably not. Then the industry would have been bigger. Even if it was still here. Then we would still be psychologically dancing around here. And the criminality rate would still be higher. Is it true in this context that "blei" content contains the color of the wall and the air combined with the criminality rate? That would be interesting to me now. I found the following. The US researchers have found out that "blei" is forbidden from the 80s since the surface cover of "blei". That the criminality rate is significantly less. Basically, the less "blei" you take into account in childhood, the more unlikely it is that you end up getting aggressive. Yes, but Michelet still has a second miracle in his book, "FCKW". We can also briefly tell you what happened there. Yes, there is a huge hole over Australia and the Arctic. In 1974, the US scientists Mario Molina and Frank Rowland, who by the way will later also receive the Nobel Prize, found out that the FCKW molecules are very bad for the ozone layer and that they wear off. The ozone layer was already thin at the time. It is a pity that the health of the people is of course extreme. There are also animals and plants because the UV radiation is much more concentrated on the earth. The cancer rate for humans has increased drastically. Plant growth is damaged. Of course, there is a FCKW ban, but probably researchers suspect that the ozone layer could still generate up to 2070, if there is no further FCKW gas. But of course there are still sources from the FCKW gas in the atmosphere. That's why I don't know exactly. I have no hope that the ozone layer could still generate up to 2070. But it has already become much better. It has become much better, but still there are still sources from the FCKW gas in the atmosphere. But 2070 would be like this. Would be cool. I think it's crazy how long you need something like that. If you just had a stupid idea what might cause irreparable damage. FCKW gas was banned in 1990. There were all state leaders in the UNO and member states. And that's really an exception. In Montreal Protocol, the production of FCKW gas can be completed within 10 years. That means that in the beginning of the '00s no more FCKW gas could be produced. In 2070 we might have a re-existing ozone layer. It's definitely a small invention. It's a big effect. But I would like to end this episode with a quote by Thomas Mitchley. He said "People who make molecules are the only ones who have the luck of the human being." If he meant climate change with luck, Mitchley was right. Wait a minute. Crazy. But I think it shows his mindset again. He wanted to help the human being. He did. I think the things he achieved were already groundbreaking. Unfortunately, they had effects that he didn't know at all. I always had an impression that there are other solutions to all these things. We also have cooling limits today that don't burn. We also found a different solution. But Thomas Mitchley found the fastest way, but also the most harmful. At that time, there was no test or at least no one who would last like today for 10 years before you got all the EU certifications for it. Just the need to have this means. With a motor, I think he could have waited a little bit, but because of the cooling limits, what this means for a progress and what this means for the health of people, for the medicine and so on. You probably wanted to go for this shortcut. I think you wouldn't have this kind of pressure today. That's why we would have the time to check things out. Thank you. Thomas Mitchley, one of those who really wanted to go for this. What's really special about this story is that several people from our Darwin-Gefälters-Hörerschaft sent us as a theme proposal. And maybe just a little call when absurd stories from the story come about people who have suffered a great epic failure, then share the stories with us. At the easiest, you actually reach us on Instagram @dawingefälters. Of course, you can also follow us. Subscribe so that you don't miss the next episode. I didn't see you that much. Yes, but it's always funny what we do there. No, follow us there. Send us your theme proposals. We're really looking forward to it when you write us. Of course, everything else is a theme proposal. What fits you so well and is on the heart. In the next week, we'll stay in the USA. Because there's going to be the first Olympic Games on the American continent. And my food was for an anamanda "Reiung an Fels". I'm looking forward to it. "Dawing gefälters" is a production by Kugel and Niere with Anna Bühler and Christian Alt. Research by Eileen Sandschak.
