Global fish stocks collapsing

Truth Out - "Commercial overexploitation of the world's fish stocks is severe," UN Secretary General Ban Ki-moon said back in 2012. "Many species have been hunted to fractions of their original populations. More than half of global fisheries are exhausted, and a further third are depleted."

According to the UN Food and Agriculture Organization, 85 percent of global fish stocks are "overexploited, depleted, or recovering from depletion."

Yet despite these alarms having been sounded loud and clear, life in the oceans is continuing to deteriorate at an ominously rapid pace.

The populations of all large predator fish in the oceans have declined by 90 percent in the 50 years since modern industrial fishing became widespread around the world, according to a shocking paper by scientists with Dalhousie University in Halifax, Canada, published in Nature in 2003. "We are losing species every day without ever knowing about them. Sometimes humans can be like a plague to the environment."

Three years after the paper's publication, the same scientists, along with colleagues from across the world, published an even more startling paper that predicted a total collapse of all fish that are currently caught commercially by 2048.

Many scientists, like Daniel Pauly of the University of British Columbia, have estimated that the total fish catch for the planet peaked back in the mid-1980s, and has been declining ever since.
