Dutch engineering student Boyan Slat announced in a 2012 TEDx talk that he had invented a way for the oceans to rid themselves of plastic with minimal human intervention.

At least 5.25 trillion pieces of plastic are currently in the oceans, a third of which is concentrated in the infamous Great Pacific Garbage Patch. Slat’s idea is to building a stationary array with floating barriers that would filter and collect floating plastic using the ocean’s natural currents.
