It is a wonderful world we live in. For thousands of years the Earth has given support to all forms of life – human beings, animals, birds, fishes, insects and plants. But now human beings are killing our planet. Many species of animals and birds have disappeared.Besides, every year people cut down more trees, build more roads, and use more land for farming. This leaves fewer jungles, fields and forests for wildlife. The country air, once clean and fresh, now may be polluted by power stations and factories. Some of our rivers are now empty of fish..

These are some of the world’s most serious environmental problems. And it’s no good pretending they don’t exist – they do.
