Talk about a legacy of shame. And apparently, plastics are the future, as the percentages of our bodies composed of plastic continues to rise.

Plague of Plastic Chokes the Seas - Los Angeles Times : ... Albatross fly hundreds of miles in their search for food for their young. Their flight paths from Midway often take them over what is perhaps the world's largest dump: a slowly rotating mass of trash-laden water about twice the size of Texas.
This is known as the Eastern Garbage Patch, part of a system of currents called the North Pacific subtropical gyre. Located halfway between San Francisco and Hawaii, the garbage patch is an area of slack winds and sluggish currents where flotsam collects from around the Pacific, much like foam piling up in the calm center of a hot tub.
Curtis Ebbesmeyer has been studying the clockwise swirl of plastic debris so long, he talks about it as if he were tracking a beast.This is known as the Eastern Garbage Patch, part of a system of currents called the North Pacific subtropical gyre.

Curtis Ebbesmeyer has been studying the clockwise swirl of plastic debris so long, he talks about it as if he were tracking a beast.
“It moves around like a big animal without a leash,” said Ebbesmeyer, an oceanographer in Seattle and leading expert on currents and marine debris. “When it gets close to an island, the garbage patch barfs, and you get a beach covered with this confetti of plastic.”
Some oceanic trash washes ashore at Midway — laundry baskets, television tubes, beach sandals, soccer balls and other discards.
Nearly 90% of floating marine litter is plastic — supple, durable materials such as polyethylene and polypropylene, Styrofoam, nylon and saran.
About four-fifths of marine trash comes from land, swept by wind or washed by rain off highways and city streets, down streams and rivers, and out to sea.
...
The Los Angeles River carries enough trash each year to fill the Rose Bowl two stories high, and despite efforts to corral some of it near the river mouth, most slips through to the ocean.Moore adjusted a trawlnet to collect trash flowing downriver. At Moore's signal, a crane operator lifted the net out of the water. Volunteers swarmed around the trawlnet, extracted the contents and loaded them into more than a dozen jars.
The jars were filled with plastic pellets the size and shape of pills. They come in all colors and are the raw material for a vast array of plastic products, from trash bags to medical devices.
About 100 billion pounds of pellets are produced every year and shipped to Los Angeles and other manufacturing centers. Huge numbers are spilled on the ground and swept by rainfall into gutters; down storm drains, creeks and rivers; and into the ocean.
From his river sampling, Moore estimated that 236 million pellets washed down the Los Angeles and San Gabriel rivers in three days' time. Also known as “nurdles” or mermaid tears, they are the most widely seen plastic debris around the world. They have washed ashore as far away as Antarctica.
The pellets, like most types of plastic, are sponges for oily toxic chemicals that don't readily dissolve in water, such as the pesticide DDT and polychlorinated biphenyls, or PCBs. Some pellets have been found to contain concentrations of these pollutants 1 million times greater than the levels found in surrounding water.
As they absorb toxic chemicals, they become poison pills. Wildlife researchers have found the pellets, which resemble fish eggs, in the bellies of fish, sea turtles, seabirds and marine mammals.
Over time, plastic can break down into smaller and smaller pieces, eventually turning to powder and entering the ocean in microscopic fragments. Some plastic starts out as tiny particles, such as the abrasives in cleaning products that are washed down the sink, through sewage systems and out to sea.
The chemical components of plastics and common additives can harm animals and humans. Studies have linked the hormone-mimicking phthalates, used to soften plastic, to reduced testosterone and fertility in laboratory animals, and to subtle changes in the genitals of baby boys. Another additive, bisphenol A, used to make lightweight, heat-resistant baby bottles and microwave cookware, has been linked to prostate cancer.
