　　Personally, I think environment pollution is an enduring problem that we have today. Vehicle emission and poisonous gas discharged by factories are major factors causing the air pollution. Sometimes, the smog and haze in big cities are so serious that people can barely breathe. Actually, haze and fog have negative impact on people’s mood and citizens suffer from dizziness and depression when they suffer from serious haze several days in a row. Also, haze and fog can cause a series of diseases, like heart disease, stroke, respiratory illnesses, birth defects and cancer.
