What should we do to protect our environment

It is very important to protect our environment. What do you think we should do to improve our environment? I think we can do the following things. First, we may plant trees. The more trees we plant, the better. Not only can we ourselves plant as many trees as possible but we can also ask other people to join us in doing this. The more people plant trees， the better. Secondly, we mustn’t throw any litter onto the ground. When you see some rubbish on the ground, please pick it up and throw it into a dustbin. Thirdly, we can collect waste paper and bottles for recycling. Fourthly, when we find some people or factories pollute the environment, we can write a letter to ask them to stop making the pollution. If they still do like this, we can write a letter about it to the TV station and the newspaper. Anyone who pollutes the environment is always afraid to be laid bare to the public.
Wherever we live we can do something around our neighborhood.
