THE OCEAN cleanup

Boyan Slat and The Ocean Cleanup have already deployed their first working prototype in the North Sea and plan to deploy the main device by 2020.
It could eventually remove more than 150 million pounds of trash from the Pacific Ocean.
The water filtration system is like one you'd find in a fish tank, but it's designed for an entire ocean.
