If you buy these shoes, you are helping clean up a poisoned Chinese lake. The shoes are made from algae that started polluting the lake a decade ago depriving two million people of safe drinking water. Now the algae is harvested from the lake and turned into a flexible, rubbery material that is used to make shoes. To get enough algae to make one pair means cleaning 57 gallons of water, which are then returned to the lake.
