Reading passage
The Earth has many natural resources. But they will not last forever. So it is very important to conserve them. It is a good idea to recycle and reuse resources. It is also important to reduce our trash.
When you recycle something, you send an old product to a factory and the factory makes a new product from it. People can make a new plastic object from an old plastic bottle.
When you reuse something, you use it again. You can use an old shoebox to plant flowers. Youcan use plastic bags again when you buy something. You can write on both sides of paper.
You can reduce by using less of things. We should reduce pollution too. Pollution can be harmful for the air and water. Reusing, recycling, and reducing will help our Earth.
