percent of our planet but in recent years this blanket has come under threat mostly from plastic pollution some eight million tons of plastic washed into the sea every year. five gigantic marine plastic garbage islands float around the world's ocean currents. the great pacific garbage patch drifts between hawaii and california it's four times larger than germany. happily the floating quagmire could get something of a purge this summer. the ocean cleanup is the brainchild of churchmen boy and slant it's a boom which drifts more slowly than the plastic which collects along behind it to be recovered for recycling to clean up this it will automatically gravitate to those places where most plastic it's and that now causes the efficiency to be a lot higher because there's just more plastic in front of the system and therefore we can outplay you have fifty percent of the batch in just five years old.
