Đoạn văn : 

     To protect the environment, we can do a lot of things. First, we must not throw trash indiscriminately in public. Do not discharge dirty water into rivers and seas. We should also plant more trees. And we need to propagate to parents, grandparents, siblings about how to protect the environment clean and beautiful. 

Trả lời :

Enviroment is the most important thing for our life. 
Environment is an essential part of our life. 
Nowadays, a variety of environmental problems affect our entire world.
But now that most important thing for our life is being polluted. 
A clean environment is necessary for a peaceful and healthy life. 
When fossil fuels i.e. oil, coal and gas are burned to provide energy for cooking, lighting etc. they form polluting gases.
In the sea, oils spills pollute sea water and kill marine life.
Artificial fertilisers pollute river water, killing wildlife and spreading disease. 
Pollution could be prevented by 
Keep clean environment
Use recycled paper to help save trees
Plant more trees
When we protect the environment, it’s mean we are protecting ourselves and our future as well.
I hope that in the future the earth will be cleaner.
