Far out on the high seas, on any given day, hundreds of fishing vessels drag huge nets, big enough to snag a 747 jumbo jet, across the ocean bottom, vacuuming up 150-year-old fish, flattening ancient reefs and destroying everything else in their paths.

TIME Magazine’s Ken Stiers writes:

Only the biodiversity of tropical rainforests rivals that of the deep sea — our planet’s largest wilderness — an aquatic wonderland that is now being systematically razed by what is likely the world’s most environmentally destructive business.

The fishing occurs mostly around the ocean’s most unique topographical formations — submarine canyons, mid-oceanic ridges and tens of thousands of seamounts (most are extinct volcanoes) — which support a stunning profusion of endemic species, many of which are yet to be discovered.
