trip civil side taking control of a d militarized officer separating his reading of expired golden heights from sir. but that's all for now. coming up next out in private show a plan that i looked at the common and poisonous gas that is not so well known. so i'm anthony holland. topic and see the beautiful my nephew. he read the city. we don't know what to screen or where is mohammed stop? he fled from northern iraq and became one of hundreds of migrants who vanish every year. somewhere in the no man's land, the lines between batteries and cleared refugees become pools in a cru see up into school config, missouri this,

i'm afraid i'll never see him again. when oh you lost on the run, starts the send, the a, c, d w, the, these colorful rings this acid lake, and this blue fire all exist because of one element. so for the yellow stuff can be both completely harmless and extremely toxic. it's found in our bodies, our food, and also in volcano. if you've ever smelled a rotten egg or fart, the copper with silver, but unfortunately heating it up also makes a highly toxic gas. it's also responsible for one of the scariest sounding environmental catastrophes. acid rain, and contributes to millions of dest every year, by extracting and burning fossil fuels, we're spewing it into the atmosphere. the story of some authorize,

both of looming crisis and environmental success, and not enough people are talking about it. software is one of the more abundant elements in the universe and combined with other elements can become one of the smallest. you can find it in the ocean, the irs crust, and the toxic atmosphere units. it's also the 3rd most common material in our bodies. our bodies are made up of around a 150 grams of solver in its solid pure form. it's both tasteless and odorless. compounds of it are found in many fluids, including broccoli, cauliflower, a, tongue in and garb. sophie is actually responsible for the strong smell that garlic makes much crushed. another sulfur compound gives broccoli and cauliflower their distinctive taste. and if you find yourself with a particularly smelly onion, that's because of itself or compound as well. these strips test for soul, for compounds and liquids. the good thing about software is that it can prevent bacteria growth and stop alcohol from turning the vinegar. it's also

sending water from wells or springs. seems like this berglund tap water doesn't contain much sulfur, but this beer and wine definitely do another place you'll find software is in the sky a little bit so. so for doc set up nap missed here. concert is what we call cloud condensation nuclei, essentially. little platforms for clouds to build around the cows father is a climate scientist and researcher clouds that can be more reflect is an inbound smartlight back space. so the combined effects lead to about half a degree celebrate of cooling globally, compared to a world where we didn't have the service on this. in other words, cell for in the atmosphere actually slows down, global warming seems pretty good, right? but soul for actually is a dark side it's one of the most reactive elements on the periodic table,

and that means it changes form easily when in contact with other elements. it's also super playable. that's why matches are covered with it. the software keeps the fire burning long enough to light a candle. burning silver can look like a hell scape, like at this indonesian volcano, when matches are lit, a small quantity of a cell for gas is created. ready and this matches a mini version of the software pollution problems. ready those gases, these yellow sulfur molecules, form and other elements are toxic. one of them is hydrogen sulfide tucker with 2 hydrogen atoms. this gas is found naturally in wetlands swamps and hot springs. it's what gives human and animal waste. it's nasty smell because it's created in small amounts by bacteria in your mouth and got and inhaling it is one of the leading causes of workplace tests from chemicals because exposure can kill you immediately. another nancy cell for gas is software dioxide. if i were to light this pure so for on fire, it would change from of fun powder into

a bad situation really quickly here. sulfur dioxide would come off of it, which is really not good for health. and that thing i shouldn't do. that's exactly what we've been doing for a long time on a planetary scale. so, so for operation is many quits by bidding for sealed fuels. edmunds and any auto research has chemical pollution in the environment. and also industry decides is refining petroleum and snow to mid totes, this visualization prepared by green piece with nasa data shows worldwide. so for pollution, coal plants in russia and oil refineries and saudi arabia and iran are some of the biggest sol for gas emission hotspots. worldwide. fossil fuels naturally contain software. they can release, so for gas when they're extracted. and again when they're burned. another source of sulfur pollution is from the metal production. some metals naturally contain sulfur. it's also used during the purification process which can release pollution into the atmosphere. a we didn't always know all of this. fossil

fuel use took off around the 19 fifties and it 1st everything was fine. but around the 1970s people started noticing something weird. the rain was more acidic than it used to be. remember how silver farms cloud, too much suffering clouds can react with other elements to form. so if you're an acid, an acid rain, oceans, lakes and rivers become more acetic, hurting marine animals. it also affects the ph of soil. we know plants the free and reduced and inspect the temperature in regarding a t h. he's also going to affects how the plants are going to up. so the nutrients that they need to grow. but software doesn't need to rain down on us for it to have devastating effect. it's harmless in this form. but exposure to solve for gases can range from irritating a respiratory tract, an eyes to nausea, neurological effects, even dest software. pollution from coal contributed to the near constant london fog

of the 19th century. people suffered and died from as 9 bronchitis, which still place those living near oil refineries and cold plants today. and silver particles also form pm 2.5. fine particles that are significant part of global air pollution if you lay to match a couple times or if you like, sitting around a campfire and you know they are placing you, but it isn't good for you. but if you're not doing that all day every day, it's not going to be that bad for your health. whereas, you know, if you're living in beijing and your air looks like a piece, oops, that's where it really starts creating various severe medical problems as my heart disease and stuff like that. and a lot of that software pollution is caused by burning coal. to fill in this outside for obvious reasons. as coal like this is essentially just pulled out of the ground . it's still contains a lot of sulfur apart from volcanoes, burning coal is responsible for more software pollution than anything else. when

burned in power plants to is, is called scrubbers can remove the software from the emissions. but if money or infrastructure is lacking, scrubbers don't end up doing so much scrubbing. there's obviously also coal that is burned outside of power plants. can berlin, for example, some apartments of coal furnaces for heating during the winter. and this is the exact fuel that they use and those emissions come out of the chimney, they're putting sulfur directly into the atmosphere. worldwide. china has been the largest, a mentor of sulfur and recent decades. because industrialization there was heavily reliant on coal. and along with burning coal, came out to our air pollution responsible for over $1000000.00 dest per year. because of this, the country has recently taken major steps to reduce software emissions. in other countries, the amount of coal being burned is actually going up. when you, it looks, if i, you wrote, you know, they need to be some energy source in what is the quick in exhaust. that is what it so that's called but it isn't all bad news. if you haven't really heard much about

acid rain or so for gas recently, because there's been a very big effort to stop at the, in the low rate conditions across the welds where we would think to lead me to the district of sulfur. didn't to be a to most viewed, much of the software is removed from oil and gas during their finding process already before it. so to consumers. extracted software is turned into pesticides, fertilizers, and so if you're a gas it, because it's a by product of the oil and gas industry, we have a ton of it so much in canada, their solid software just sitting around as a result, atmospheric. so for gases have decreased significantly over the past decades. and regulations are still getting tighter. 2020. so the 1st ones on shipping fuel before then ships brenda dirty is 12 full of sulfur. but in now the last 8 or 3, there's been more studies about the health impacts and burning the steel in ports with a couple studies suggesting that somewhere in the range of 20 to 60000 people globally, you may die prematurely, you do to exposure to. so for that,

that pollution from shipping, and it turns out that about 10 percent of all of the silver dioxide that we make globally comes from shipping. and with less self or at least into the sky, there are fewer clouds over the ocean. this usually good news has one small problem . fewer clouds mean less sunlight is reflected. this is predicted to one the planet equivalent to 2 years of extra greenhouse gas emissions. quite a tricky trade off, but experts say reducing sulfur emissions. it's still worth it to walk combating software. pollution is one of those rare environmental successes. this stuff is stopping us from putting our party has on just yet. removing solver from fuels has caused a significant drop in worldwide pollution. we're going to see it fall further from the recent regulations on marine fuel, but there's still more software in the atmosphere than there should be. an enforcing software regulations in one part of the world, only partially solve the problem. if oil refineries elsewhere are still releasing it into the air. so all regulations are important. shift away from fossil fuels is

the only thing that will tackle toxic solve for gases for good. if you want to know more about elements, important for climate change and to see a slide more stuff on fire, don't forget to subscribe. we have new videos that come out every friday. the
