Animals Need Protecting
Animals are natural resources that people have wasted all through our history. Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States aloneare considered in danger.
Why should people care? Because we need animals, and because once they are gone, there will never be any more.Animals are more than just beautiful or interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems. For example, when farmers killed large numbers of hawks, the farmers' stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice, with no hawks to keep down their numbers, the rats and mice multiplied quickly.
Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger. Quite a few countries have passed laws. These laws forbid the killing of any animal or planton the danger list. Slowly, the number of some animals in danger is growing.

Saving Land for Endangered Animals
There is only so much land on the earth, and so what we can do with it is limited. Some people believe that human needs for farmland, housing and industry should come first, while others believe that some land should be set aside for endangered animals. I am of the opinion that we should reserve some land for the world’s animals for the following reasons.
First, mankind’s need for land is constantly growing. If the demand is not checked in some way, humans will eventually develop all of the earth’s available land. At that time, mankind will have no more room to grow, and all the wild animals will have disappeared, as well as other valuable resources. Second, humans are able to innovate and can use the land that they already possess in more efficient ways. Animals are unable to do this. Once their land is taken away from them they will die. Third and last, endangered animals are an important part of the biodiversity of our planet. If they disappear, we cannot predict what the effect will be. Therefore, we should treat such animals as a valuable resource to be protected.
To sum up, the world’s endangered animals are an important resource and we should protect them by setting aside some land for them. Although mankind’s need for land continues to grow, people are intelligent and inventive enough to put the land they have to better use. In this way, we can have enough land for farming, housing and industry, and preserve the biodiversity of the planet at the same time.
