TreeHugger Asks: What "Dumb" Questions Do You Have About the Environment?

Remember, in second grade, when there was that one math problem, or idea in science class, that you just didn't get, but you didn't want to raise your hand because you thought it was a dumb question and you didn't want your friends to make fun of you?

We've all been there, and it's no fun at all. TreeHugger doesn't want anyone to feel that way about green topics and the environmental world, so we're starting a new series of posts to answer these questions. So we want to know: what have you been dying to know? What haven't you been able to figure out? Leave a comment with your questions below, or leave your questions in the thread in TreeHugger Forums. Either way, we promise not to make fun of you.

So let's hear 'em! There's really no such thing as a dumb question, so ask us some questions so we can get answering.
