Hello, teachers and students: Today, the topic of my speech is "Animals are good friends of human beings". I believe that half the students in our class have fed small animals. When you are sad and disappointed, it seems to be able to read your mind and try its best to make you laugh. Every day you grow up, it is with you. Some people may say that animals are not good friends of human beings. Animals rob people of food, and animals often attack people. But let's think about it the other way around. Why do animals do this? Because the food plundered by us humans has almost disappeared, coupled with the excessive felling of trees and forests, the living space of animals is getting smaller and smaller, and the living environment is getting worse and worse, so we have to fight. On the other hand, animals can also help people. Dolphins, for example, can also help drowning people after human training. For another example, there is a kind of longicorn beetle in the world, which is very fierce and specializes in destroying trees. No matter how hard human beings try, they can't stop its reproduction. Finally, people found a woodpecker, which is the natural enemy of longicorn beetles and helps people protect trees. As far as food is concerned, people on the grassland often drink goat's milk and milk. When people are threatened by famine, it is these animals that come forward to help us tide over the difficulties. You see, animals not only do not harm human beings, but also help human beings to protect the environment and maintain ecological balance. Therefore, animals are good friends of human beings, and we should live in harmony with them and share the same earth with * * *!
