五、阅读短文并回答问题。
What do the following animals have in common? Pandas, tigers, whales, lions and camels, they are all in danger! Animals are in danger for many reasons. Sadly, the human activity is the main one.
Excessive(过度的) hunting: For centuries, humans have hunted elephants for their tusks(长牙), killed tigers for their fur, and caught many other animals for meat.
Human migration(人类迁徙): In 1505, Europeans discovered a beautiful island in the Indian Ocean named Mauritius. They brought dogs, pigs, monkeys, and rats with them. It was bad news for dodo birds. They did not have any natural enemies before. They picked up fruits falling down from trees and built their houses on the ground. Shortly after humans came, dodo birds were in big trouble—man killed them for their meat, and those animals broke their homes and ate their food. The number of dodo birds became less and less and then this kind of bird was extinct(绝种的). The last dodo bird was killed in 1681.
Nature remaking: People cut down forest for farming and houses and build dams(水库)
to make sure that they have enough water to use. When people are remaking nature to make their lives comfortable, the land for animals to live on becomes less and less.
