They are home to many animals, such as monkeys, parrots, and jaguars. They also have thousands of different plants. Rainforests are important because they produce oxygen and help keep the Earth cool. However, people are cutting down trees, which destroys the rainforest. We should stop cutting down trees and protect these wonderful places. That’s why I think rainforests are so special. I hope we can all work together to save them. They are the lungs of our planet. Let’s protect them. Yes, we can. That's my promise. Thank you. 1 学科网（北京）股份有限公司 $
