We should save our environment, because ultimately we are going to live in it. Our environment was spoiled by us, and we should change this by saving it. We could save it by not throwing garbage, not littering, etc. It is although our home, and we should treat it like one.

Apropos of the statement, I think "Save Environment", is nowadays only regarded as a general slogan. We should try to make it a reality. Saving environment involves a lot of work; as we have destroyed it a lot, already. Cleanliness should be the first step. We should prevent throwing garbage, littering all around; rather, we should pick up the previous dirts and throw everything in a waste bin.
