Holy! I just saw a post from my Aunt on my facebook wall about an invention to clean up the ocean.
(Hopefully this link works...)
If not here is the gist "Boyan Slat has unveiled plans to create an Ocean Cleanup Array that could remove 7,250,000 tons of plastic waste from the world’s oceans. The device consists of an anchored network of floating booms and processing platforms
that could be dispatched to garbage patches around the world. Instead
of moving through the ocean, the array would span the radius of a
garbage patch, acting as a giant funnel. The angle of the booms would
force plastic in the direction of the platforms, where it would
be separated from plankton, filtered and stored for recycling."
