Global warming

“Global Warming"

I think that the reason of global warming is happened by over population. As more factories building around the world, there are more factories building around the world, the scientists examine the chemical solutions such as testing nuclear, and the natural disasters were happened around the world.
Firstly, as over population in the world there are many people built factories in order to produce a lot of products. It is really caused a global warming according to the smokes from factories. Moreover the people need raw materials to make the products. In this raw materials, It causes a lot of warming an area.. Finally It will become an enormous global warming such as using raw materials in Factories. We knew that there are more technologies caused the global warming. People all around the world use the materials. After using that the dispose their materials on the trash but there are some people that burn the rubbish on the field. Especially the people from rural places make global warming such as burning the rubbish on the field. Therefore, It is caused a global warming.
Secondly, we knew that nowadays there are some scientists that examine the nuclear that producing a lot of chemicals. There are some chemicals caused a global warming. Some country they make weapons to defend their self or to declare the wars, but they didn't know to cause a global warming. It is destroyed an oxygen from environment, and it is polluted the air and caused a global warming. Moreover, There are some county that there is no specifically stated a law such as destroying an environment. They didn't protect an environment, and the people are cutting trees and bamboo so on.... It is really caused a global warming. So in this reason, it is caused a global warming and polluted air.
Finally, we mostly heard about the disaster a round the world. Otherwise, it is caused a global warming. For example, Last month we heard an earthquake occurred in China. There were a lot people lived in China. And there is a lot of building and factories were built. After an earthquake occurred there, it will be polluted air and destroyed an environment, we knew that the pollution from this disaster would increase a global warming.
All in all, A serious global warning will cause a lot of factories were built around the world, the scientists examine the chemical solutions such as investing nuclear, and the natural disasters that happen around the world.
