Homework
假定你是李华，你需要为校报写一篇文章呼吁每一个人来保护动物。需包含以下要点：
1.解释人类动物是如何影响动物的；
2.提出相应的保护动物的措施。
Help protect animals!
Animals are of great significance to our world, and we must work together to protect them. Some of them bring us joy. Some provide us with food and clothes. Still others have led us to key advances in science and technology. Last but not least, animals help maintain the balance of our ecosystem. Unfortunately, many species are endangered because of us.
Human activities have done much harm to animals. Some human activities, such as hunting and fishing, directly cause populations of many animals to fall. Other human activities have an indirect impact on animals. For example, the destruction of the Amazon rainforest has led to the loss of animal habitats.
We must try to do whatever we can to protect animals. By reducing our use of wood and paper, we can save not only trees, but animals living in the forests. Likewise, we should try to reduce the amount of beef that we eat, since many trees in the Amazon are cut down to make room for cattle farming. But above all, we should spread awareness about the importance of animals and their need for protection.
