Research different ways of recycling.
All people use a lot of stuff together. We buy everything; toys, clothing, food and so on. All those things we use, but we also throw a lot away again. For all that make things, all kinds of raw materials from nature are needed. But they can run. And when we throw things, the waste must be processed. That takes energy, and there are common pollutants in free. More and more of these materials can now be recycled.
Recycling means that waste and old materials are used for new products. For example, there can be quite a lot to be used; paper, wood, plastic and much more.
