Study: 8 Million Metric Tons of Plastic Dumped Into Oceans Annually

hypnosec writes: According to a new study (abstract) that tracked marine debris from its source, roughly 8 million metric tons of plastic gets dumped into the world's oceans annually. Plastic waste is a global problem, and until now, there wasn't a comprehensive study that highlighted how much plastic waste was making it into the oceans. "The research also lists the world's 20 worst plastic polluters, from China to the United States, based on such factors as size of coastal population and national plastic production. According to the estimate, China tops the list, producing as much as 3.5 million metric tons of marine debris each year. The United States, which generates as much as 110,000 metric tons of marine debris a year, came in at No. 20."

    Assumption based on uniform distribution.
    Plastic distribution in the ocean is not homogeneous.

    Please read up on the "gyres" in the ocean. Places where a large corriolis current causes mechanical concentration of suspened particulates in the oceans. The concentration of suspended microparticles of decaying plastic are sufficiently high in these locations that it is affecting bottom-tier filter feeders, which suck in the plastic particles as if it were plankton, then concentrate it further inside their bodies, which are then consumed by higher trophic level fauna, with toxic results.

    I think the point here is surface area, not volume.

    Because the excretory systems of simple invertebrates of this type (Corals, sponges, etc) preclude the existence of a dedicated GI tract as you would normally envision it. (A sponge is literally just two layers of cells that suck in water on one side, and push out water on the other, for instance.) They are unable to digest the particle, it stays large, and it cannot pass through. This is bad for the filter feeder, and toxic to the organism that consumes the filter feeder.

    Because there's a few countries that haven't seen the shining light that is the metric system.

    so yes, it matters.

    The real problem *is* money.
    There's a fairly new technology out that uses plasma to melt and reduce landfill garbage into a non-toxic sludge which can then be processed into more useful stuff, the resulting heat from which can sustain the plasma reaction once it's started. The problem is it costs a lot to purchase and install. Landfills are *extremely* profitable businesses. I read not long ago that each truckload of waste driving out of manhattan is worth well over $10,000 in profit. One truck can probably make a couple of trips per day. Subtract a couple $100 for fuel and the driver's paltry salary and you can see how much of a cash cow it is.

    The clamshell packages weren't made for you the consumer... it was originally designed for the retailer to slow down shoplifting.

    After all, it's much harder to smuggle out a bigger-than-your-pocket-sized plastic container with a 64GB geek stick in it, than to simply smuggle out the geek stick itself. Being hard to open w/o damaging it prevents a shoplifter from just taking that 64GB geek stick out of its original package and putting it into a 8GB package (with an obviously cheaper price tag) before strolling to the checkout stand with it.
