It is generally known that our beautiful cities has been polluted a lot with the development of our society. Nowadays, air pollution, light pollution and water pollution have grown more serious these years. Such as, cars, trucks and buses etc. are the major sources of the air pollution. In my opinion, the best way to solve this problem is to use bikes instead of these kinds of vehicles. When we are traveling in a shrort distance, or going to work in the same city we are living, we can go by bike instead of driving our cars. As we know, Bike needs no energy, it just need us to start it, so if we often use bike in our daily life, it can not only help us save energy, reduce air pollution but also do good at our health to make up for the lack of exercise in our workdays. In short, bikes are environmental and helpful for our health. It is an excellent way to solve air pollution.
