People love and need animals. They keep them in their homes and on their farms. They enjoy going to zoos, and watching animals on films and on TV.
Little children love to play with toy animals. But people are a great danger to animals too. They take their land, and cut down the trees where animals have their homes.
They pollute the rivers and seas, and kill big animals for their skins or for medicine. Now there are about 7,000 species of animals in danger. What can we do to protect the animals of the world - from us?
