As the development of technology, the earth's resources becoming less and less.The environment is getting worse and worse. So, as a student, we should save energy in our life.Start with me, start with the little things around us.

First, we should save water.When we do not use water, we must turn off the tap.And then, when we go to school, we can take the public transport or walk instead of taking a car. Last but not the worst, we should save the food、water、paper、trees, and we can plant more trees on the earth.

We all live on the earth. It is our duty to protect the environment.
