text: I think that it would be wise to consider changing your thoughts to letting the students who have at least a C average to play sports. If they do fail to have a grade at or higher than a C that student should not be able to play sports untill they get their grades up to at least a C. I think that you should consider movinwhy you should limit car usage? limiting car usage is a great way of helping the air from pollution, less accidents, and less money throwing  out the window. you could just walk, run ride a bike or anything that doesn't require you to use money with. Doing those things could even keep you healthy. pollution is getting  out control these days to much greenhouse gases in the air. its bad we needa do something before it can kill us. like in all of the passages it tells why not using cars is a great way a better way to not us cars.
