Boyan Slat ( a student) explains that after a dive in Greece was conserned about ocean’s pollution and he decided that he has to act!
Ever since the plastic pollution problem gained widespread attention at the beginning of this century, there have been many ideas for cleaning it up. But these all involved vessels and nets that would ‘fish’ for plastic. Not only would by-catch and emissions likely cancel out the good work, but also, due to the vastness of areas in which the plastics concentrate, such an operation would cost many billions of dollars, and thousands of years to complete.
In 2012, Boyan Slat —then 17 years old— proposed a passive concept that could overcome these challenges.
