At first, it was a little hard to remember. But after a week, it became a habit. My parents also joined me. Now our family produces less waste. I feel proud because I am helping the earth. Part 2 I think our community can do more to solve the rubbish problem. First, the government should provide more recycling bins in every neighbourhood. Second, we can start a recycling programme and invite volunteers to teach people how to sort rubbish. Residents should use reusable bags and bottles. We can also hold a “clean-up day” every month. If everyone takes part, our community will become cleaner and greener. Part 3 Sorting rubbish is very important because it helps reduce pollution and saves resources. When we recycle paper, fewer trees are cut down. When we recycle plastic, less waste goes into the ocean. Some people think one person’s action doesn’t matter, but that is not true. Deng Xiaohong started alone, and soon her whole village joined. Every small action adds up. Environmental protection starts with me. If we all do our part, we can make a big difference. 1 学科网（北京）股份有限公司 $
