We humans are capable of enormous devastation, but every now and then, we’re able to agree to stop the worst of our transgressions. We no longer regularly scour the oceans for the great whales only to boil them down for margarine and pet food. We’ve stopped killing wild birds en masse to make hats out of their plumage. We’ve effectively banned DDT — a pesticide that nearly emptied the skies of hawks, falcons and even the bald eagle.
Bottom trawling — a destructive industrial fishing practice that indiscriminately brings to market about a quarter of the world’s wild-caught seafood — should be next. A bottom trawl is a weighted net that is often wider than a football field. As it is dragged along the sea floor, the trawl captures, kills or maims everything in its path. Around 19 million tons of marine life meets its end this way every year — that’s more than the combined weight of all the people in Brazil. At least another six to seven million tons of unwanted organisms are killed annually and dumped overboard. If a similar technique were deployed in the Amazon, people might be more likely to recoil from the mangled pulp of jaguars, toucans, sloths and trees deemed necessary sacrifices to bring meat to market. At our seafood counters, we never see the mangled pulp. Underwater, ignorance is bliss.
