I think there are lots of things that we can do to make our environment better in life. No.1, throwing away rubbish on the street casually is not a good thing, we should avoid doing anything like that. No.2, we could recycle things that we used in life. Like second hand paper for example. No.3, getting rid of habit of self driving. By doing so, the air quality would be better than before. More importantly, if each of us in the world can get this point, the living environment would be improved, undoubtedly.
