Dear sir or madam,
The environmental pollution is worse and worse today. We can’t afford to wait any longer to take action.
Water is polluted in some cities and countryside, we have no clean water to drink. Many trees are being cut down, some animals are getting less and less. Some factories are producing dirty air into the sky, the population is increasing faster and faster, resources are getting less and less, etc. .Not only does it affect our lives and health, but it also has a great effect in the future.

unhealthy. The ploblem is there because the rubbish
【参考范文2】
collectors do not come often enough to collect the rubbish. The people living here may also be throwing away too much rubbish.
We could try to ask people to produce less rubbish. I suggest that rubbish collectors collect rubbish more often as well. I believe that a better environment can be created in this town and we could all work together to acheive it.
Your faithfully,
Wang Xi
