Everyone should take the action to reduce haze(雾霾), which is harmful to our health. First of all, I believe if we plant more trees, there will be less haze in their city. Trees can absorb exhaust fumes(尾气) from cars, thus reduce pollution. Second, the government should punish the factories where produce too many fumes. Exhaust fumes is the main cause of haze and do greatly harm to people’s health. Maybe we can move factories to areas where few peoples live. Third, I think it was a great idea to encourage people to use public transportation. Last but not least, we can call in citizens to ride bikes if they travel short journeys.
