Map of the Great Gyres

This is a lovely map of the major gyres that dominate our oceans although we barely understood this outside of  academe.  that has obviously now changed as we suddenly understand this to be the global junkyard.   Obviously not acceptable.  Yet the great news is that mother nature appears to be grinding it all up and digesting it.

Long term we must replace all our  industrial output with materials that are way more readily digestible.  This is not a lot to ask, but impossible to ask without a global authority tasked to provide global regulation.  As such an authority has yet to be constructed able to be immune to bribery and influence, we and Terra must continue to suffer.


It is not even about cost as marginally more expensive and safer protocols amply exist but the hidden cost of waste management is never booked.

Map Details Extent of Plastic Debris in Five Ocean Gyres

When a research team set sail on a nine-month, worldwide expedition in 2010 to study the impact of global warming on Earth’s oceans, one of their projects was to locate the accumulations of plastic.
They found plenty. They explored the five huge gyres, which collectively contain tens of thousands of tons of plastic. The result was the creation of a compelling, first-of-its-kind map of this debris.

But in the process, they realized that the plastic in the gyres didn’t begin to account for the enormous amount of plastic that’s been manufactured since the mass production of plastic began in the mid 1940s.
In a National Geographic report, marine biologist Andres Cozar Cabañas, who was part of the Malaspina expedition led by the Spanish National Research Council, said:
“Our observations show that large loads of plastic fragments, with sizes from microns to some millimeters, are unaccounted for in the surface loads. But we don’t know what this plastic is doing. The plastic is somewhere—in the ocean life, in the depths or broken down into fine particles undetectable by nets.”
While there’s been considerable alarm raised about these gyres of floating plastic, the missing plastic could be having negative impacts we don’t yet know about. As National Geographic reports, the study of marine plastic debris is new, dating back only to 2004, when British marine biologist Richard Thompson concluded that most ocean debris is, in fact, plastic.
The discovery of the missing plastic raises a host of questions. Oceanographer Kara Lavender Law of the Cape Cod-based Sea Education Association, part of a team currently researching issues surrounding marine debris, told National Geographic:
“We are at the very early stages of understanding the accounting. If we think ten or a hundred times more plastic is entering the ocean than we can account for, then where is it? We still haven’t answered that question. And if we don’t know where it is or how it is impacting organisms, we can’t tell the person on the street how big the problem is.”
Among the possibilities: it’s being consumed by small fish that are eaten by larger fish caught for human consumption, such as tuna and swordfish, and ending up in the human food system. Or it could be finding its way into the ecosystem of the world’s least explored region, the deep ocean.
“Sadly, the accumulation of plastic in the deep ocean would be modifying this enigmatic ecosystem before we can really know it,” said Cozar.
