A huge net is being dragged across the sea floor, destroying everything in its path. Ahead of it bloom undersea forests and their hundreds and thousands of living creatures, both plant and animal; behind it is a desert. The net is pulled to the surface and most of the dead and dying life forms in it are thrown out. A few marketable species are retained. [Trawling] is like taking a front-end loader and scraping up your entire front garden and shredding it, keeping a few pebbles, and dumping the rest of it down the drain.
— Margaret Atwood
