Save the Animals.

Animals are natural resources(资源) that people have wasted all through our history.

Animals have been killed for their fur and feathers(羽毛), 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 alone are 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(平衡) of nature.Destroying one kind of animal can create many problems.

For example, when farmers killed large numbers of hawks(鹰), 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(繁殖) 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(禁止) the killing of any animal or plant on the danger list.Slowly, the number of some animals in danger is growing.

(2023·顺义区二中月考)There's nothing like having a best friend forever—that person who you can have fun with and talk to.July 30 is the International Day of Friendship.Maybe you can seek to encounter a new friend.And while we're talking about friends, don't think humans are the only ones who know a thing or two about friendship.Check out these friendly animals in nature who help each other out.

An elephant and an olive baboon (东非狒狒) can be friends? It sounds amazing, but it's true.You can find this pair of friends in the grasslands of Africa.This unusual pair can help each other out like any good friends would.The elephant uses its front teeth to make a waterhole in the sand, and it lets the olive baboon have a drink from this “well” when it gets thirsty.In return, the baboon tells the elephant when danger is near.It climbs up to the treetops and calls out so its friend knows that it's time to move on.

In the sea world, the goby fish(虾虎鱼) and the shrimp are well­known for their friendship.The shrimp provides a home for the goby fish, while the goby fish provides a guidance service for the almost blind shrimp.You see, the goby has great eyesight (视力) and stays close to the shrimp.As the shrimp moves around, the shrimp is feeling the goby with its antennae (触须) from time to time to make sure it's still there.If the goby senses danger, it will return to the home and the shrimp will follow.

The langur monkey has a very good friendship with the chital deer (斑鹿)．While the langur monkey eats in a tree, it drops leaves to the ground.This is good for the deer because sometimes there's not much food.The deer will follow the monkey and eat whatever food that is dropped.And in return, when the monkey comes down from the tree, the deer will stamp heavily to tell the monkey if it senses danger.
