Intense article about plastic marine debris.

"We still have limited tax dollars to spend and scarier nightmares to fear. No one — not Pallister, not Moore — will tell you that plastic pollution is the greatest man-made threat our oceans face. Depending whom you ask, that honor goes to global warming, agricultural runoff or overfishing. But unlike many pollutants, plastic has no natural source and therefore there is no doubt that we are to blame. Because we can see it, plastic is a powerful bellwether of our impact upon the earth. Where plastics travel, invisible pollutants — pesticides and fertilizers from lawns and farms, petrochemicals from roads, sewage tainted with pharmaceuticals — often follow. Last June, shortly before my voyage in the Opus began, Sylvia Earle, formerly N.O.A.A.’s chief scientist, delivered an impassioned speech on marine debris at the World Bank in Washington. “Trash is clogging the arteries of the planet,” Earle said. “We’re beginning to wake up to the fact that the planet is not infinitely resilient.” For ages humanity saw in the ocean a sublime grandeur suggestive of eternity. No longer. Surveying the debris on remote beaches like Gore Point, we see that the ocean is more finite than we’d thought. " LINK
