As the world develops faster and faster, the level of living gets higher and higher; however, at the same time, the pollution is becoming heavier and heavier, which causes the global warming, one of the most serious problems at nowadays. And the outcomes can mainly result from the development of industry, the manual damage of nature, and the increasing population.

To be the largest origin of global warming, the development of industry which is one of the main ways to consume coals, petroleum, and natural gas, contributes a lot to rise the whole temperature of the world. When people making things such as cars, computers, and boondoggles, they usually use the energy by burning petroleum; however, they do not concern about the result of that. Actually, every time you burn the petroleum, it will release a lot of heat which directly rising global temperature; also, a large quantity of carbon dioxide, which is a greenhouse gas, will be created accompanied that. What’s more, as the problem becomes more serious, many developed countries do not slow down burning the petroleum, which makes the matter worse.

In addition, the damage of nature by man is another reason for causing global warming. As we know, the acreage of forests are reduced year by year, simply because people need woods to build buildings, or to make some boondoggles; however, they do not think about trees which can absorb carbon dioxide and release oxygen, thus, as a result, by gathering more and more carbon dioxide, the temperature becoming higher and higher. Though a lot of people have realized this problem, there are still many people continuing damage the environment.
