Pacific Ocean Garbage Patch Worries Researchers
NeverVotedBush writes with an update to a story we discussed early this month about an enormous accumulation of garbage and plastic debris in the Pacific Ocean, a thousand miles off the coast of California. The team of scientists has now returned from their expedition to examine the area and say they "found much more debris than they expected." The team will start running tests on the samples they retrieved, and they are preparing to visit another section of ocean they suspect will be full of trash.
"The Scripps team hopes the samples they gathered during the trip nail down answers to questions of the trash's environmental impact. Does eating plastic poison plankton? Is the ecosystem in trouble when new sea creatures hitchhike on the side of a water bottle? Plastics have entangled birds and turned up in the bellies of fish, and one paper cited by the National Oceanic and Atmospheric Administration estimates 100,000 marine mammals die trash-related deaths each year. The scientists hope their data gives clues as to the density and extent of marine debris, especially since the Great Pacific Garbage Patch may have company in the Southern Hemisphere, where scientists say the gyre is four times bigger. 'We're afraid at what we're going to find in the South Gyre, but we've got to go there,' said Tony Haymet, director of the Scripps Institution."
This story remind me of the George Carlin bit on the environment:

Famous last words before being eaten by Cthulhu.
The mass production of plastics didn't take off until about the 1950s. What we're looking at is approximately 60 years worth of garbage. The pile they have looked at is approximately twice the size of Texas. If that doesn't seem large now, then it certainly will in another fifty years if we continue to discard plastics at our current rates. I suspect that you'd find that our use of plastic has curved upward sine the 50s, rather than remaining at a constant rate... so I think that hoping for an island only four times the size of texas by 2050 would be optimistic.
Considering that the bottom of the food chain resides in said "thin layer" (and much of the top of the food chain feeds there) the potential impact is magnified well beyond its volumetric measure.
This is why I only buy family-size cheetos, unlike those selfish bastards that buy lunch-size packets.
Fuck systemd. Fuck Redhat. Fuck Soylent, too. Wait, scratch the last one.
Ok, I guess I'll speak up for conservatives here...
Yeah, I'm extremely skeptical that global warming trends we've seen are the result of our fossil fuel usage. If you follow the money, there are a lot of people in the environmental movement pushing "carbon credits", and are poised to make a boatload of money by exploiting others' guilt, while doing nothing to actually solve real problems. But no one wants dirty air or water. There are plenty of good reasons why we should be reducing our oil and gas dependency (just inhale deeply on a bad smog day if you live in LA). And one would be an idiot to argue that a bunch of plastic in the ocean (or other obviously man-made debris or pollutants) are anything but a problem caused by humans, and needs to be solved by humans.
Believe it or not, I consider myself an environmentalist. When I was a bit younger, I did a lot of hiking in the mountain ranges near my home. I think nature is something that needs to be carefully protected, because it's far to easy to trample it under the foot of progress and industry. I support our national park system, and conversation efforts everywhere. I'm switching my light bulbs to more efficient halogens as they need replacing (not by force of law, though!). I'll be replacing my gas-burning car with an electric when they come out with a practical, affordable model, and I'm looking forward to doing so.
However, I also believe that we can strike a balance between responsible stewardship, individual liberty, and capitalist enterprise. I just happen to believe that you need to be extremely judicious in applying the force of law to every problem you need to solve. Growing the power of government nearly always comes at the expense of individual liberty, so I prefer that not be our first solution, but the last.
Irony: Agile development has too much intertia to be abandoned now.
You mean worse than oh say, FISHING?
Seriously, filtering the top 6 inches of water, even going so far as to remove anything bigger than .5 micron shouldn't be such an impossible task, I'm envisioning a boat with a wide modified bow that collects the bow wave for filtering.. perhaps a group of them in an arrow formation filtering thier way back and forth across the gyre. Heck done right they could burn the plastic as fuel, capture the co2 in the sea water to help the phytoplankton recover.
As to to the depletion of the microorganisms in that layer, if the plastic is THAT deleterious we are likely doing the species(s) a favor by removing the badly damaged members, freeing up the space for healthier members to reproduce.
There are two things that make this difficult. The amount of garbage is the size of Texas and a lot of the plastics have dissolved.
A crew went to the gyre and recorded a documentary (a free documentary by VBS.TV Garbage Island ), hoping to see giant island of garbage. While they did not see the island, what they saw was far worse. The plastics have dissolved and estimated that the amount of dissolved plastics is higher than the microscopic sea life and natural oceanic nutrients in the water. The gyre is now very, very gross. The garbage is either so scattered or very well dissolved that there is no way that it can be cleansed that easily.
