Plastic, Now more Dangerous than once thought...!!!

"The world produces an estimated 10 tons of plastic a second, and between 5 million and 14 million tons sweep into the oceans every year. Some of that debris washes up on beaches, even on the world’s most isolated islands. About 5 trillion pieces currently float in surface waters, mostly in the form of tiny, easy-to-swallow fragments that have ended up in the gut of albatrosses, sea turtles, plankton, fish, and whales. But those pieces also sink, snowing into the deep sea and upon the amphipods that live there.

Brooks eventually found plastic fibers and fragments in 72 percent of the amphipods that the team collected, from all six trenches that they had surveyed. In the least polluted of these sites, half of the amphipods had swallowed at least one piece of plastic. In the 6.8-mile-deep Mariana Trench, the lowest point in any ocean, all of the specimens had plastic in their gut."

More Plastic... Now, Lack of Oxygen :

"Escaping predators, digestion and other animal activities—including those of humans—require oxygen. But that essential ingredient is no longer so easy for marine life to obtain, several new studies reveal.

In the past decade ocean oxygen levels have taken a dive—an alarming trend that is linked to climate change, says Andreas Oschlies, an oceanographer at the Helmholtz Center for Ocean Research Kiel in Germany, whose team tracks ocean oxygen levels worldwide. “We were surprised by the intensity of the changes we saw, how rapidly oxygen is going down in the ocean and how large the effects on marine ecosystems are,” he says.

It is no surprise to scientists that warming oceans are losing oxygen, but the scale of the dip calls for urgent attention, Oschlies says. Oxygen levels in some tropical regions have dropped by a startling 40 percent in the last 50 years, some recent studies reveal. Levels have dropped more subtly elsewhere, with an average loss of 2 percent globally."
