Is it hot in here or is it just Earth? Now you can wear your eco-awareness on your organic cotton sleeve with this limited-edition "Hotter Than I Should Be" t-shirt, available with a donation of $50 or more to World Wildlife Fund.

This is one message tee that we approve of. Money donated through WWF's global warming website will go to support their worldwide climate change and conservation initiatives, a plan that couldn't come soon enough. Unless a change is made immediately, in just 10 years, it will be too late to ensure that there are natural resources left to provide habitats, fresh water, food and clean air for people as well as animals.

To learn more and give back to Mother Earth, go to worldwildlife.org/globalwarming or call 1-800-CALL-WWF.
