The Fallacy of Cleaning the Gyres of Plastic With a Floating “Ocean Cleanup Array”
As the policy director of the ocean conservation nonprofit 5Gyres.org, I can tell you that the problem of ocean plastic pollution is massive. In case you didn’t know, an ocean gyre is a rotating current that circulates within one of the world’s oceans – and recent research has found that these massive systems are filled with plastic waste. There are no great estimates (at least scientific) on how much plastic is in the ocean, but I can say from firsthand knowledge (after sailing to four of the world’s five gyres) that it’s so pervasive it confounds the senses. Gyre cleanup has often been floated as a solution in the past, and recently Boyan Slat’s proposed ‘Ocean Cleanup Array’ went viral in a big way. The nineteen-year-old claims that the system can clean a gyre in 5 years with ‘unprecedented efficiency’ and then recycle the trash collected. The problem is that the barriers to gyre cleanup are so massive that the vast majority of the scientific and advocacy community believe it’s a fool’s errand – the ocean is big, the plastic harvested is near worthless, and sea life would be harmed. The solutions starts on land.
