Nowadays people are more aware that wildlife all over the world is in danger. Many species of animals are threatened, and could easily become extinct if we do not make an effort to protect them. There are many reasons for this. In some cases animals are hunted for their fur or for other valuable parts of their bodies. Some birds, such as parrots, are caught lively , and sold as pets.

For many animals and birds, the problem is that their habitats -the place where they live is disappearing. More land is used for farm, for houses and industry, and there are fewer open spaces than there once were. Farmers use powerful chemicals to help them grow better crops, but these chemicals pollute the environment and harm wildlife. The most successful animals on Earth, human beings, will soon be the only ones survived unless we can solve this problem.
