coming does not get drunk. why do gravitational waves squeeze out bodies? how much do we need per day? try stop. cons, praying for help. find the office gets lost on data. we use science and i'll take top 10 of april 22nd 2020 for a massive fire broke out at the guns support landfill site in valley. this was no ordinary fire, but a symptom of a much larger problem because the pool was supposed to have been shut down in 2002 instead of thirty's, reportedly kept sending up to 700 truckloads of the trash there. every day. it has filed up almost as high as it touched my home when ways to compose this religious meeting, highly flammable gas. so i'm not really surprised at that the whole thing burst into flames. but me thing is also a super potent greenhouse gas trice, global warming. and as our mountains of trash keep growing more and more of it gets

seeping out of the complex waste sites around the world. but there are ways to stop this foot scraps, plastic bottles, pizza boxes. think about how many things you throw weight each day, depending on how in where you leave. this might different a lot. different indian thought is all 500 trends of garbage every day. for the average american troops to point to keels, by the way, the us as the roll champion in waste generation per capita. this file grows along with cds and the rising standard of living. this was part of the problem and does it pool? in 1984 when the landfill 1st opened, dallas population was not even 7000000. now it is about $34.00 meeting. the thirty's weren't ready for that. and on the planet right now, we're 8 beaten people, producing $2.00 tons of rubbish every year. according to this, you went study 38 percent ends up where it shouldn't some 2700000000
11:04 pm
people like access to basic waste management services. so no protection multiplan, no disposal, due to ramona's, the technical director at the international solid waste association. she's one of the supervisors of this study. so for the lack of those options, what do people end up doing? they take the reast be stopped, the blown on, don't pay the $1.00 that goes on and dump that we spent. until this is leading to a practice. there's no precise number for how many such dumpsite stay on the planets. but each one is one to many. and it is important to distinguish here between dump sites and landfills. they have a different things on site is with an absolutely new environment and controls when it drains the water filters through the waist and fonts, leach it potentially toxic cook, tell us many heavy chemicals and back to re, among other things that so called of the trash leaking into the environment,
11:05 pm
either to walk a ways your soil is or your and by open blending. and so all of these are emissions that are ending up in the environment that are arming. sure. one hand it's harming the environment. and when i talk about your with health, essentially, if you have contaminated waste is going into a fluid systems under this mountain of thresh, where there is no oxygen. something else is happening. material breaking down organic waste and producing meeting, one of the worst greenhouse gases in the short term is over 80 times more potent that hitting the planet than carbon dioxide. on the way sector accounts for 3 to 5 percent of all greenhouse gas emissions sites and landfills are the biggest contributors. and there are defending terry landfills which have more environmental controls to try to mitigate all those problems. they started to evolve in the 20th century, especially in the 2nd half. also because the material using all products had become
11:06 pm
much more toxic to the natural environment. currently, the united states has more than 2600 landfills. that's a lot of fresh americans have historically relied on landfills for many reasons. just the name of fuel consumption levels are really high. the country has wide open spaces available and using land. so was quite often seen as the cheapest option in the short term. that is why half of the trash produced by americans ends up there. so it's no wonder that the holes, the planets biggest landfill of its kind, according to the gain is world records the effects landfill. outside of las vegas, it's big enough to accept waste for the next 250 years. landfill operators to use several ways to tackle the problems of dumping trash, to protect the ground from toxic chemicals. they started with a large hole in the ground line with giants in front of the layers of synthetic materials. kind of like a huge into swimming pool with a big plastic sheets in it. at the bottom, there's
11:07 pm
a drainage system to remove the lead shape that's generated. sensors can also be placed at the bottom layer to detect any possible leaks after delete is treated, it is turned into a usable water, are now with days and engineered land. so can also capture most of the midday to meet it by making a kind of trash livonia. that stops most of it from going to the atmosphere. as the garbage is dumped, heavy tractors compact it. it didn't cover it with an impermeable layer. dump compact. culver repeat over and over again. then that kind of system of pumps. 6 out most of the gas is generated, including the mid thing. at this points, there are 2 options. the main thing capture can be burned to a process called flaring that turns it from a super harmful greenhouse gas into a regular home for one c o 2. but this is a huge waste. your comes to the 2nd option. me think can generate heat electricity or renewable natural gas compar vehicles, for example,
11:08 pm
many us landfills use this technologist and we've been here that media that altogether they produce and i'll stick with an advantage it to power when meet and homes. this technique, problems to reduce methane emissions by 60 to 90 percent. so problem solved not quite using special infrared cameras on planes and satellites. researches have detected substantial leaks, currents measuring methods which usually rely on ground of cetaceans couldn't detect them. the research has found that us landfills and meet $1.00 times more meetings in official reports. but it's not all bad news. this data can help linfield managers to detect leaks and reduce emissions straight away. however, not all solutions and the skills need to be so high tech that businesses recommendation to reduce methane emissions from landfill is much simpler in more straightforward, reduce the amount of organic waste in them because the methane emissions from landfills are produced when organic matter decomposes underneath a pile of garbage without oxygen. if we are not going to be,
11:09 pm
i'm going to destination that with these duct waves. it is that the thoughts probably be situation will talk out. i. this is sharon collie, a scientists. we specialize in waste management in india, being alone middle adam and i was in when, when does very good flooded the condition of the day the and so you feel do it and then scientifically, neck stuff gentlemen. uh, i think we get back to the stop the meets in admission city in countries like india where around 50 percent of the garbage is what waste avoid them using landfills can be really effective and some places are being quite successful in implementing this policy. take my sewer, for example, with a population of more than one median. it produces between 40500 tons of waste daily . the 3rd is designed a decentralized system in which trash gets collected, segregated, and composted inside their neighborhoods. here it is important to remember that
11:10 pm
composting is primary anaerobic process with oxygen, where micro organisms breakdown organic matter. it can relate small amounts of meeting if it's not properly done. if there isn't enough be ration. that is quite, quite often you'll see people turning the compost regularly in mice to about 50 percent of all waste is combusted for that the collector goes from door to door residents, them properly separate their trash. do be, find officials say only 5 percent of the trash goes to land so their goal is 0 waste video risk management, those like no waste shown go for the plant or the line for today and simulation plan. so we had completely managing the risk though. we've had receiving from our different lots of my city corporation, the combust produced is sold to local farmers in the horticulture department. when you look around india, this may feel like a dropping the ocean. but it is a great example that shows it can be done. combusting also sorts out another huge
11:11 pm
problem, almost one 3rd of the countries farmland surface from slight different nations barkley, due to the heavy use of chemical fertilizers. now we're getting a compost is being used on farms to restore the land. this is a great example of climbing up the letter of the waste higher key at the very bottom of it is the worst possible way to get rid of the trash open burning or dumping. that is where the west, the waste we just saw, would probably end up then comes disposal without energy recovery like kinds of land feeding or incineration. next, this waste energy, which is an umbrella term for a few different methods like the west landfill, we saw generate electricity out of me. thing here comes with cycling. this is where the composting examples are even better. it is to reuse things often referred to as up cycling. and at the top of it is prevention and reduction. that bart depends a lot on the waste producers. so companies as well as individual consumers going up in the pyramids is not always easy. closing dump sites and making lens feel better
11:12 pm
is a challenge and come to a long process. but it can be done like in rio de janeiro. it once hosted, let in america's biggest dumpsite. judging that, i'm not sure which received over 80000000 tons of cabbage in 30 years. the surrounding monroe forest was devastated by it to locate the opportunity give me much sense and of it. they search for a faith to my my here to keep call laugh place. they showed one shouldn't be bad. we saw the push fellow side, not by edge. went about marty most got at least the biologist responsible for this restoration project. don't. this is think they both of them get that by just was point, you know, truth bit, i'm sure i my, or i did your mind gives the mileage one about it, some safety thing, but it didn't link the main roof forest captures, a huge amount of su, to this kind of invitation can absorb up to 4 times more carbon than other forest. and now we use waste goes to modern landfill. outside of the city. the site
11:13 pm
captures most of its methane emissions. according to the operator generates enough to manage the power seat of $90000.00 residents. it is a modern engineered landfill which cost of their own $90000000.00 us dollars. but that doesn't mean that the problem is solved in nearby grandma. sure, they're still illegal, dump sites. and even in the restoration project itself, there were problems with leaking, leach $8.20, which now seems to have been sort it's this approach isn't cheap and it's not perfect, but it does have a lot of potential. look at this graphic. it shows regions that's to have a huge number of open dump sites. in this case some experts suggest it's moving from dump sites to lentils would already be a step forward on the top of that separating at least organic trash before sending it to the landfill. like in missouri is something we can do when a global level of test reducing waste is the top priority to can also be reached
11:14 pm
worldwide is placed at the top of the pyramids. let's face it right now. we're producing more and more trash worldwide. the power of smart waste management, instead it can reduce costs in the long run to higher up and the waste pyramids, you go, the more money you can make from the trash to just by making energy or re sending trash this company into more ways to collect in a controlled way, the less com it does to things harmons and the less money is needed to clean up this mess the. what about you? do you have any problems with dump sides or landfills nearby ready leave an equal solution to the wrong? let us know in the comments below. keep the light button a subscribe to our channel for releasing new videos for you every friday the,

the, sometimes it's hard to find what you're looking for. but we've got something for you. this shadows of jumping colors, these cod costs and video shed light on the dog is devastating. colonial har is infected by germany across up and he employed the scorched post farms and destroyed lights. what is the legacy of this wide spread races, depression? today, the screen we need to talk about here, the stories, shadows of german colonialism. the the washington
