The main idea behind the Ocean Cleanup is to let the ocean's currents do the work.
U-shaped floating barriers are attached to the ocean floor by anchors, but fish and animals can still swim underneath it without getting trapped.
The barriers will move more slowly than the plastic and act as "artificial coastlines", picking up rubbish as they go.
Then the floating plastic is forced to a collection point, where it can be taken out and shipped to shore for recycling, into things like sunglasses and car bumpers.
