当今全球环境问题变得越来越严重。请你根据漫画内容，以李华的名义给“China Daily”写一封信，描述这种状况，并提出

One possible version:
Dear Editor,
Nowadays environmental problems are becoming more and more serious all over the world.
With the development of industry and agriculture, cars make loud noises and give off poisonous gas. Because of population expansion and overdevelopment, resources have become less and less. Trees on the hills have been cut down and waste water is being poured continuously
into rivers. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even poses a great threat to man’s existence.
We must face the situation that exists and take actions to solve our environmental problems. We hope that all these measures will be effective and bring back a healthful environment.
Yours truly,
Li Hua
