Two years ago the scourge of the Great Pacific Garbage Patch, and of the plastic pollution that jeopardizes marine ecosystems around the globe, inspired 19-year-old aerospace engineering student Boyan Slat to imagine the Ocean Cleanup Array. Next year this 2,000-meter long floating device is to be put to the test for two years off the island of Tsushima between South Korea and Japan. The ultimate goal? Clean up the GPGP in a decade while humanity figures out a way to stop dumping plastic into the oceans.
