Liu Ying has an important part animals since she was ten.

Our environment is polluted. One kind of pollution is from transportation and industry that burn much coal. is from people. For example, (fisherman) kill sharks for fins. This is not only cruel but also harmful to the environment. We know sharks are the top of the food chain in the ocean's ecosystem. Besides, no (science) studies show shark fins are good for health. What upside down thing they do! People also throw litter everywhere. They even throw plastic, waste iron, metal or bottles into bins. So I think we can't afford (wait) any longer. A president said we should take action in (develop) laws to protect our environment and we should take part in the environmental study from the bottom of our hearts.

We should turn off lights when we leave rooms. We'd better use reusable bags instead of (pay) for plastic bags. We should put old things to good use. We can recycle books and paper. Wed better bring waste back to life with our creativity. For example, we can reuse the wooden gates that (pull) down. We can turn ugly things into beautiful (work). There are many advantages of doing these. We can get inspiration from them and it doesn't cost anything.
