I'm not going to go into whether global warming is real or not. That sort of thing is up to you to decide. If you believe in global warming, or are not really sure either way, then here's a way you can help. We Can Solve It is a Facebook application that helps you give to The We Campaign to help stop global warming, without dishing out a dime.

What you do is earn point by doing things like signing petitions, writing letters to the editor, to inviting friends to add the We Can Solve It application, sharing videos and sharing news articles.

Challenge your friends to help too and see who can earn the most points. When you earn 10 points, $1 will be donated to help stop global warming.
