Listen to Your Mother (Earth): Go Vegan!
In the ’80s, people sang “We Are the World,” but for Earth Day 2013, PETA gave that idea a very literal spin: Instead of wearing their hearts on their sleeves, these good folks took off their sleeves (and everything else) in favor of blue and green bodypaint for a demonstration in Vancouver. They reminded everyone who saw them that we can help the planet simply by choosing healthy and humane vegan foods.
So remember: If you want to save the world and its inhabitants (or just look your best without clothes), going vegan is the best way to start!
