More than 100 million sharks are killed annually for their fins. Enter PangeaSeed, a Tokyo-based grassroots organization to raise awareness on the plight of sharks around the world. PangeaSeed’s mission is to create an open dialogue with the global community on the need to preserve and protect sharks and their habitat. They are doing this through volunteer activism, art, film, music and photography. Recently, they collaborated with several artists on a series of exclusive T-shirts. With prices ranging from $25-$55 (plus international shipping), keep in mind you’re not just buying another shirt: this time you’re making a donation to saving sharks and keeping PangeaSeed “trucking along.”
