Nowadays the most important problem in the world is global warming. Everybody believes that the world temperature is increasing because of carbon dioxide from our cars, factories and power plants and so many others. Furthermore studies show that the world has risen by about 1F in the last century. Moreover the climate change is caused by a lot of things such as a rise in the sea level, rainfall patterns, plants and humans.
There are lots of causes which make global warming happen. First thing is atmospheric greenhouse gases (water vapor, carbon dioxide, and other gases) Scientists say that temperatures would be much lower than they are now without the greenhouse effect. Second thing is air pollution caused by cars, trains, factories and burns. Nowadays the United States is the largest source of global warming pollution.
Finally everybody has to change the way they live, so that we can avoid huge changes in the future.
