Deadr Sir,
I am writing to you because I heard about our rubbish dumps. It is not good. This situation affect to s our health.
To begin with, people can compost old food waste. By doing this, we will have better quality soil for plants.
Another way is recycling. Putting all waste into the trash is not good idea. There are special containers where these  rubbish can be segregated. It can be reused without contaminating the soil.
In concludsion, there are several ways to help the environment. If people start taking care of the environment and segregating waste, it will come out for good.
Yours faithfully,
Xyz
