Two years ago，Boyan Slat，a then 19—year—old university student in Holland，made the claim that he 61 clean up the oceans vast accumulation of plastics in about five years．
62 a scuba diving holiday in Greece，Boyan Slat，aged 16，found there were 63 (many)plastic bags than fish in the sea．He started seeking for a solution to ocean plastic 64 (pollute)．In 2012，he decided to make his intentions public．It sounded like a pipe—dream to many when Slat first described his idea，but he felt it was so simple it just might work．
Slat came up with 65 he called a floating“Ocean Cleanup Array．”Instead of going after the plastics，he designed an array(排列)of long floating barriers to let the ocean currents concentrate the plastic 66 (it)．The system of floating barriers is over a mile long．
The system had its first proof-of-concept test，which 67 (perform)in the Azores Islands．After proving the feasibility(可行性)of the array in doing what it was supposed to do，the real evaluation of the array will take place in the second quarter of 2016，in a two—year pilot project in real—world conditions off the coast of Tsushima，an island 68 (lie)between Japan and South Korea．
This pilot project is worth watching to see if it 69 (work)．And if it does work as 70 (expect)，we have something even bigger to look forward to．
