There’s tons of trash in the oceans. Plastic, metal, wreckage all over the place. Near Hawaii, there’s an area particularly dense with garbage over 1.4 million square miles in area. To put that in perspective, it is five times the size of Texas. They call it the “Pacific garbage patch”.

One Dutch entrepreneur named Boyan Slat has created a way to help it. He wants to build the largest floating barrier ever deployed. It would use to ocean’s currents to capture plastic in the Pacific Ocean.

“There’s a lot of talk, and not a lot of action in the world of plastic pollution,” says Slat.
