How can we keep the environment? One way is to remember the Four Rs: Reduce, Reuse, Recycle, and Rebuy.
Reduce
We need to use reusable materials and products. We also need to reduce the packaging that is used for new goods in shops. It is important that we improve our use of paper, cardboard, glass, metal, plastic, and other materials.
Reuse
Very often we throw away items that still could be used. For example, we sometimes throw away clothes when they no longer fit us, or we buy some new furniture and throw away something that could be repaired. Other people could make use of these items. We need to change our bad habits.
Recycling
By recycling, we can make something new from something old. This saves natural resources(资源). It also helps to offer jobs.
Rebuying
If we buy recycled goods, we help to save resources and avoid waste. The money we spend also supports the recycling process. Remember the Four Rs!
Of course, there are many other ways to improve our environment, we know. Let’s try them.
