The air pollution is so dangerous for people in my area. There are two problems about causes and effects. About causes, firstly, many vehicles discharge dust and smoke into the environment. Besides, factories dump waste poison out. Finally, people littering anywhere, such as parks, beaches, schools and even on the way. About effects, firstly, people can suffer from many respiratory diseases. Second, people can't live long because of lack of oxygen. And last, it will destroy the ozone layer and make it easier for the Sun rays to penetrate the Earth. In short, I think we should protect the air's purity before it's too late.
