Giant Trap Is Deployed To Catch Plastic Littering the Pacific Ocean (nytimes.com)
A nonprofit has deployed a multimillion-dollar floating boom designed to corral plastic debris littering the Pacific Ocean (Warning: source may be paywalled; alternative source). The 2,000-foot-long structure left San Francisco Bay on Saturday. According to The New York Times, Ocean Cleanup "aims to trap up to 150,000 pounds of plastic during the boom's first year at sea." From the report: Within five years, with the creation of dozens more booms, the organization hopes to clean half of the Great Pacific Garbage Patch. Over the next several days, the boom will be towed to a site where it will undergo two weeks of testing. If everything goes as planned, the boom will then be brought to the garbage patch, nearly 1,400 miles offshore, where it is expected to arrive by mid-October, said Boyan Slat, 24, the Dutch inventor and entrepreneur who founded Ocean Cleanup.
The cleanup system is supposed to work like this: After the boom detaches from the towing vessel, the current is expected to pull it into the shape of a "U." As it drifts along, propelled by the wind and waves, it should trap plastic "like Pac-Man," the foundation said on its website. The captured plastic would then be transported back to land, sorted and recycled. The boom has an impenetrable skirt that hangs nearly 10 feet below to catch smaller pieces of plastic. The nonprofit said marine life would be able to pass underneath.

People For The Ethical Treatment Of Giants will start a protest campaign.
Most of the plastic in the ocean comes from a handful of rivers. Put the giant trap in the mouths of those rivers, and you'll catch a lot more.
Eight million tons of plastic is dumped into the Pacific every year, mostly by third-world countries. This floating boom is estimated to collect 150,000lb (68 tons) a year. So to stand still, you'd need 8000000/68 of them, i.e. 117,647 multimillion-dollar floating booms. Let's be generous and say they cost $2m each. That's $235,294,118,000.
As there are 195 countries in the world, it would be cheaper and far more effective to use that $235bn so that each country in the world runs a $1bn campaign to recycle/replace all plastic. Though considering that most of the plastic comes from just 10 countries...
> Most of the plastic comes from India and China
and the so-called developed nations (a) started it and (b) are doing their best to keep it running. Where do you think most of the crap at WalMart is coming from? Exactly.
That's "exporting pollution".
Wise up before spewing nonsense.
Tiny fragments of plastics are not going to be caught by such floating device.
The big chunks of plastic visible at the surface are only a fraction of the amount of plastic in the ocean.
The tiny bits of plastic are ingested by sea life and pollute all the food chain.
I know no solution for this other than stop using oil based plastics as disposable material entirely. But this device is not going to solve anything. At best it will hides the issue if it can remove the large and visible plastic chunks.
