Do animals matter?
We know about and can give names to about one million animals.But there are more than thirty million species and animals in the world. Every year some of this species are disappear and we never see them again. But with thirty million different species? do one or two matter? Different people give different answers to this question,but more and more people are saying, "Of course they do - they are all important!" So, why do people think that?
One answer is this: animals make the world a richer place,a more beautiful and a more interesting place for us to live in. Secondly, animals help us in many important ways. They give us meat to ear and milk to drink, and we can make things to wear from their coats. Scientists learn a lot from animals and this help them to understand people. Doctors take things from animals alive or dead to help sick people. Thirdly it is natural for us to protect animals because we are animals, too.
Many of this living things are in danger. Without our help a lot of this animals are going to die. People and animals live in the same world. Our land is their land; our trees are their trees; our rivers are their rivers. We want to protect animals because at the same time we are protecting our world.
