Last Tuesday, a Roots & Shoots project was set up in my community. As I walked down No.1 Street, I saw volunteers 13 (encourage) people to join in. Volunteers stated that many human activities ignored the environment, 14 (leave) wildlife 15 (suffer) badly. 16 (shock) by the message, many people felt that we should act at once.
While recently many people have become more concerned about environmental protection, there are still some who haven’t, 17 (think) that someone else will deal with the problem. However, if everybody had that attitude, environmental problems would exist all the time. We should remember — it’s not just "me"!
