Scientific American: Overfishing and pollution have pushed life in the high seas to the brink of collapse, according to a new report from the Global Ocean Commission. “The oceans are a failed state,” David Miliband, co-chair of the commission, told Reuters. The commission has implored governments to set a five-year deadline to deal with threats to the health of the high seas, which are marine waters outside national coastal zones; these seas cover almost half the globe.
Fishermen catch around ten million tons of fish from the high seas every year, with a value of $16 billion dollars. It’s a vast ocean of resources only recently made accessible by advances in fishing technology. The report warns that a combination of technology and big fuel subsidies have enabled industrial fishing fleets to heavily exploit 87% of the fish species there. Eighteen countries hand out billions of dollars in subsidies; the United States bestows fleets with $137 million for a catch worth $368 million.
Pollution, largely from plastics, also endangers ocean health. The abundance of plastics in the marine environment has risen tenfold every decade in some locations, and poses a hazard to sea life when they eat it or get entangled in it. Habitat destruction, climate change, ocean acidification, and biodiversity loss also pose a danger to ocean ecosystems. [Continue reading…]
