Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

Researchers Map the North Atlantic Ocean Garbage Patch

A high concentration of plastic garbage is polluting the Atlantic Ocean north of the Caribbean, says a new study by researchers from SEA, the University of Hawaii and Woods Hole Oceanographic Institution.

Kara Lavendar Law, one of the principal researchers,  announced the findings of a 22-year study at the Ocean Sciences Meeting in Portland, US.

Dr Lavender Law said that she and her team of Sea Education Association undergraduates had picked up 64,000 plus small pieces of plastic garbage measuring up to 1cm across, using fine mesh nets  towed by a research boat.

“We found a region fairly far north in the Atlantic Ocean where this debris appears to be concentrated and remains over long periods of time,” she said.

“More than 80% of the plastic pieces we collected in the tows were found between 22 and 38 degrees north. So we have a latitude for [the patch where the] rubbish seems to accumulate.”

The “plastic density” was a maximum of about 200,000 pieces of garbage per square kilometer, Dr Lavender Law said. “That’s a maximum that is comparable with the Great Pacific Garbage Patch.”

“We know that many marine organisms are consuming these plastics and we know this has a bad effect on seabirds in particular.” She said.
