Here's the perfect gift for that person in your office who uses styrofoam cups everyday for their morning coffee. The Global Warming Mug's ($13) continental shores disappear when hot liquid is poured into it. This may seem grim at first, but just remember that by simply using the mug everyday, you are actively saving the earth from global warming! Really, it's an encouraging reminder to keep up our earth-conscious choices.
