Everyone in this town should play a part in cleaning it up.
To cut down air pollution, we should take the bus or subway instead of driving.
The river used to be so clean.
Let’s take action now!
All these small things can add up and become big things that can improve the environment.
Dear Sir/Madam,
I have lived in this town ever since I was born and I love this town very much.
I think that there are beautiful areas in this town, but there are also areas that aren’t attractive, like the rubbish disposal areas at the bottom of our apartment blocks. There is rubbish coming out of the bins, and flies, cockroaches and rats running all over the rubbish. It is unpleasant to look at, smelly, and it makes the environment very unhealthy.
Sample writing:

We could try to ask people to produce less rubbish. I suggest that rubbish collectors collect rubbish more often as well.

Yours faithfully,
