Global Warming

I didn't really think global warming was such a big deal until i read about it. I think what is causing global warming is stuff like air pollution from cars and buildings because if we breathe that stuff in it's not good. I believe that we should be concerned because some effects about global warming is plants drying up and animals becoming extinct and if the animals become extinct then there is a chance of humans dying and if plants dry up then there would be less oxygen for us humans. Also if it keeps occurring then things like disease could spread and humans could die from breathing in air pollution so people should be more concerned than they already are. People could be doing things differntley like they could carpool and recylcle to help the environment more. People are just taking the easy way out of things and that way is actually destroying our planet and everything in it.
