Our environment is very important for our lives 。 We need the fresh air， the clean water and so on 。 In the past， there were many trees around us ，the air was fresh and the river was clean。
But now，people cut down many trees。 Air pollution and water polloution are very serious 。 The environment around us becomes very terrible 。
We should protect our environment。 First， we should plant many trees to keep water。 Second ， we can ride a bike or walk to the school and work。
。 Third ， we shouldn’t throw the dirty water into the river 。 Fourth， we shouldn’t use the plastic bags。
Finally， we can ask more people to join us。
