    In order to protect environment, it is very important to learn about the environment. There are many ways to understand how to protect the environment, such as reading books, asking someone and so on. You are students. In your spare time, you can read as many as books. Books in the library are worth reading. They will help you learn. Ask your classmates or librarians for some suggestions. They have good ideas. You can also get information about the environment on some good websites. Besides these, I have some suggestions.

In our everyday life, some people use less energy by carpooling. For example, three or four persons can ride together in one car instead of driving three or four cars to work. Usually it is time-saving and convenient to carpool with their neighbors to take their children to school. Whenever we use electricity, we should turn off lights, the TV, the computer and so on when we don’t use them.   On the other hand, we should use energy-saving products. Some products, like environment-friendly new energy cars, are made specially to save energy. These cars can travel longer than ordinary cars. They produce less pollution, too. Some products like computers and TVs with the ENERGY STAR label （标签） ® are made to save energy. The products with these labels will help us protect the environment.

Secondly, we should buy recyclable products instead of non-recyclable ones. Recyclable products usually take less energy. When we go shopping, pay attention to the recycle mark on the package: make a circle and three arrows.
