Over 30% of the natural world has been seriously destroyed by humans   over the last 30 years. This is because the number of people living on Earth is nearly six billion  . All of these people need food, space and energy. As a result, lots of Earth's natural resources will be used up. When we destroy our earth to get natural resources such as wood or oil, animals often lose their living space. They cannot have enough food, and they will get hurt or die. The World Wide Fund for Nature (WWF) is an international charity. It tries to prevent humans from destroying more of nature than is necessary. For example, in China WWF is working with the local government to reconnect   some small lakes in Anhui Province to the Yangtze River and to create  more protected areas so that China's natural beauty will not be lost in the future. WWF works in more than 50 countries, saving rainforests and stopping hunters from killing rare animals and protecting traditional ways of life in areas where they are in danger of being lost. WWF's main goal is to encourage development that does not harm the environment and the animals that live in it. Even though the charity is known all over the world, and a lot of people support the goals of WWF, not so many donate money often. This makes it difficult for the charity to do all the things it wants to do. How has WWF helped in China?
They have protected traditional ways of life. They have helped to protect China's natural beauty. They have saved many rainforests in Anhui Province. They have built some bridges over the Yangtze River.
