We know that we will pollute the environment if we do not use materials wisely. People have founded many programmes to save materials and protect the environment. 3Rs is one of them. 3Rs stands for Reduce, Reuse and Recycle.

Recycling is changing the waste materials into new products. For example, we recycle waste paper to make carton boxes. We should recycle as many things as possible. If we reduce, reuse and recycle our resources, we will save energy and money. Moreover, we will help to prevent pollution and global climate change.
