We took part in a voluntary activity organized by our school in Sunday. We gathered at the Sunshine Square but gave out leaflets to passers-by, tell them the importance of environmental protection. The leaflets soon draw the attention of the public. One of us also made a public speech to tell people some knowledges about protecting the environment. They were also told where to take action in a properly and efficient way. The voluntary activity has been offered us an opportunity to contribute to our society and I have learned many from it. I think everyone should be concerned about our environment and take active part in improving it.
