学校准备在各班召开一次“保护环境，从身边做起”的主题班会。请你就这个话题按要求写一篇发言稿。

Good morning, everyone.

I think most of us have realized that the earth, which is home to all human beings and other lives, has been polluted seriously. To protect the environment is one of the most important things that people have to do .Good environment can make people feel happy and fit. It can improve our life. All the people, including our students can take part in the protecting activity. We should plant more trees and flowers around us. We shouldn’t cut them down. Besides, we should stop factories from pouring waste water into the river and waste gas into the air. Whenever we see litter on the ground, we should pick it up and throw it into dustbins. Never spit in public. It’s our duty to protect the environment. And we must take actions right now. Thank you!
