Since the winter last year，the haze has occurred a lot of times.Haze is air pollution in which is mixed up with dust， smoke and other dry particles ，and it obscure the clarity of the sky and interacts with the natural environment.This kind of air pollutant come from a variety of natural and manmade sources. Natural sources can include windblown dust， and soot from wildfires. Manmade sources can include motor vehicles， and industrial fuel burning， and manufacturing operations. The one of the main cause that touches off haze is manufacturing operations. Many factories were over measure produced the smog that had over the standard and the smog seriously influence the air become air pollution.

　　It has done great harm to our daily life.many traffic accidents happened just because of the heavy haze weather，more and more people have to go to see the doctor because the serious disease caused by the haze，quite a lot of flights have to be put off，a great number of people have to stay at home for fear of the poisonous air caused by the haze.

　　People have realized the great harm caused by the smog and the importance of protecting the environment.people all over the country are taking measures to reduce the smog weather.the government suggests people go to work or school with the public traffic， such as the bus and the underground.Also we should plant more trees.One of effective solutions to help eliminate haze is to make some chemistry changes during the manufacturing process，so it could reduce harmful emissions which are produced by manufacturing operations　　According to me， I will go to school by bike or on foot， and I won’t throw the waste anywhere.in addition， I will tell the people I meet to protect the environment as possible as they can.would you like to tell me some good ideas?i’m looking forward to your reply. We are all in this together! We shall survive and thrive together!
