Dear schoolmates,

I believe everyone’s contribution (贡献) can make a big difference.
Dear schoolmates,
Elephants are the largest mammals on land. They can live as long as 80 years. However, these days the number of elephants is becoming much smaller. Because people cut down forests they are losing their homes. Also, people kill them for their ivory. Elephants are in great danger. I think we should try our best to protect them. First, we should help make rules to stop people from killing elephants. Second, we shouldn’t cut down trees. Third, we shouldn’t buy anything made of ivory.
I believe everyone’s contribution (贡献) can make a big difference.
