Redaction About How to Keep my Region Clean

I just did wrote a redaction that i need for tomorrow and i would like to kbow know my errors.

I think that we must keep our region clean, because many times I see litter in the street and it isn't good for the image of our region.
So, to avoid this, we could do some activities to reduce the litter in my town.
As For example, the people could recycle his their rubbish and also they could reuse their shopping bags his bags to buy.
In short you have to care for the enviromental in order to live much better.

Could anyone could tell me more vocabulary about this theme.? Thanks.

Is this an assignment for class?
