Last Sunday, my classmates and I went to the neighboring community near their school. On arriving there, we gave a speech on how to protect our environment, where attracted a lot of people. After the speech, people realized they should take a bus or ride a bike instead driving to reduce air pollutions. Then we were divided into five groups and try to collect the rubbish in the community. Influencing by us, many people joined us and began to pick up the rubbish. It wasn't long before the community looked clean or tidy. Though we were a bit tiring, we still felt very happily. Now the environment around us is becoming the better and better.
