Ancient forests in danger ... deep under the ocean. Biologists estimate that somewhere between 500,000 and 5,000,000 marine species have yet to be discovered. Many of these species are in serious danger from the world's most destructive fishing practice - bottom trawling.
Mountains under the sea
The deep ocean floor has its own mountains called seamounts. They rise at least 1,000 meters above the surrounding seafloor. Amazingly, the Earth's longest mountain range is not on land but under the sea - the Mid-Oceanic ridge system, which winds around the globe from the Arctic Ocean to the Atlantic. It is four times longer than the Andes, Rockies, and Himalayas combined!
Seamounts are uniquely rich areas of biodiversity. Think colorful forests of attached cold water corals, soft seapens, sponges and seawhips, sea spiders and lobster-like crustaceans. Many seamount-dwelling species are not found anywhere else, and it is believed that some are confined to only one or two individual seamounts.
Number 1 Threat: Bottom Trawling
Unfortunately, the commercial fishing industry has gotten to know about the rich pickings that exist in deep waters. The industry has extended its unsustainable fishing practices into previously unexploited deep waters and seamounts using a technique called bottom trawling.
Bottom trawling involves dragging huge, heavy nets along the sea floor. Large metal plates and rubber wheels attached to these nets move along the bottom and crush nearly everything in their path. All evidence indicates that deep water life forms are very slow to recover from such damage, taking decades to hundreds of years - to recover if they recover at all.
If allowed to continue, the bottom trawlers of the high seas will destroy deep sea species before we have even discovered much of what is out there. Think of it as driving a huge bulldozer through an unexplored, lush and richly populated forest and being left with a flat, featureless desert.
