As we all know, all living things will die without oxygen (氧气). Oxygen comes from all kinds of plants. Rainforests play the most important part in making oxygen, and they also help us in many other ways.
Rainforests take in heat (热量) from the sun and this makes the earth cooler. Because the more heat reflects (反射) into the sky, the warmer the other parts of the world will be. That's the reason why rainforests can control the climate.
Rainforests provide us with a lot of wood. We use wood to make paper and furniture, such as beds, chairs and tables. Also we use wood for building houses to protect us from the sun, the wind and the rain. In most parts of the world, people cook food and keep warm by burning wood.
Rainforests are the world's drug (药物) store. According to research, more than 25% of the medicines we use today come from plants in rainforests. However, only a few rainforest plants have been checked for their medical value (药用价值). We believe that our best chance to beat diseases is somewhere in the world's rainforests. But it's a pity they are becoming smaller and smaller day by day. I think we should try our best to protect them.
