The number of people living in the rainforest is rising, but the rainforest itselfis becoming smaller!
During the 20th century, huge areas of rainforests were cut down. More and more people in Brazil and Indonesia moved into rainforest areas to find land for living. Local farmers cut down trees to grow crops. Large companies(公司)have also moved into the rainforests to develop their factories.
The problem is that the area of the rainforest is becoming smaller and smaller. Scientists say that destroying(破坏)the rainforest is the earth and should be stopped. But why?
Rainforest plants help to clean the air. What's more, different parts ofrainforest plants can be used to produce useful medicines and maybe the key to solving serious health problems.
So how can we solve the problem? Governments can make some rules to protect their forests. Companies can createjobs elsewhere, so that fewer people have to live and work in the rainforests. Farmers are encouraged to plant crops in certain areas, and this helps to stop the soil from being washed away and produces better crops.
More than half of the plants and animals that live in the rainforest can't be found anywhere else in the world. It is important to make sure that these forests are used well and protected by people.
