Spring is coming . The flowers will start blossoming (开花)and the trees will be filled with colors. It’s time of the year for people to plant trees. Planting trees is a good way to protect our environment. But most of us don’t have a place to plant trees. So what can we do for protecting the environment? We can make a difference from the others. For example, we can think about a way to make people cut down fewer trees. As we know, paper is made from trees. If we use less paper, we can save a lot of trees. Then we may have a problem that how to use less paper. Let me tell you my ideas.                                                   
Reducing Our Paper Waste
Every day we just use the paper and we don’t think about where the paper comes from.Let us think about wasting a piece of paper is like wasting a tree. We can start with reducing the amount of paper products that we use. This could be done by such a simple way as using e-mail instead of writing notes.
Reusing

We could reuse paper that is clean on one side for drafts, notes and even photocopies. As students, we could reuse paper by doing our research online or at libraries rather than buying lots of written paper. Sharing books or buying a used textbook for school is another way of reusing.
Recycle
We should consider recycling notebook paper, newspapers, magazines and colored paper. We can buy paper towels, tissues, and toilet paper that have been made from recycled paper. Don’t throw away the wasted newspapers or books which are not useful to you.
