One possible version:
How to protect/save our environment/world?
The environmental pollution is more and more serious today. We have no clean water to drink because
of water pollution. And when trees are cut down, some animals disappear. There is more and more dirty
smoke in the air. People's health has been greatly affected by air, noise and water pollution. Many people
died of diseases. In order to live a better life, it's time for us to protect our world.
Firstly, we shouldn't throw away rubbish everywhere. And we should recycle, reduce and reuse things,
for this saves money and reduces pollution. Use things for as long as possible. Don't use plastic bags. Also,
we must plant more trees and stop people cutting them. We hope our world is more and more beautiful.
