Factories is one of the cause to global warming. Because in factories they either burn or produce things. And when they make things in factories they use machines and those can create pollution which will rises to the air and eventually be apart of global warming.
Car can really be a cause because there are more than 1.2 billion vehicles in the world, image how much pollution is released in a minute. Cars also produce smoke which is contains carbon dioxide and other greenhouse gases that causes global warming.
Fossil fuels is one of the most common reason for global warming. Mankind activity which is using fossil fuels created more greenhouse gases which affect the atmosphere. So when we produce greenhouse gases the air gets thicker with more chemicals So more heat is held in. So when we breath in these chemicals in the air we get lung disease cancer and it also causes the trees because trees need fresh air to live too and humans.
Global warming can create a lot of problems. One is too much air pollution and this problem is really bad. In Beijing it is very foggy and you call that a SMOG. A smog is a mixture of smoke and fog which contains Sulfur dioxide(SO2) which is also bad for you because it can cause people to be sick and also give diseases. In Beijing, there is more than 21.5 million people and SMOG can form around cities and houses so it’s not safe for kids and adult to go outside.
The sea level problem is that lots of glaciers and icebergs are melting each year.In Antarctica 1.8 to 3.1 meters which means 40 percent of ice is gone in less than 30 years.In some islands in the world like Sri Lanka, the sea level is rising so the island will probably be under water in a few years.
Our solution is to try at least once a day Do any of those challenges on the picture to help reduce global warming and air pollution released.
