First up: A Stop Global Warming bracelet from Roots. Made from 100% recycled scrap leather in Canada, this bracelet’s available in five different colors and costs $5 — all of which is donated to StopGlobalWarming.org.

If you’re vegan — or simply want a slimmer bracelet — there’s the I’m Tired of Global Warming bracelet. Made from recycled tires and metals, this bracelet costs $10 — $5 of which goes to StopGlobalWarming.org.

I'm not really the message-wearing type, but judging by the popularity of Lance Armstrong's yellow bracelets, many people are! Would you buy one of these for  your wrist?
