A Plague of Plastic

What we do on land affects even the most remote parts of our planet including our oceans. In the North Pacific Gyre, a rotating body of ocean currents roughly 1,000 nautical miles northeast of the Hawaiian Islands, the magnitude of human impact is powerfully clear. Trash, notably plastic waste, is accumulating here and turning our oceans into a synthetic soup. Everything from tiny plastic fragments to fully intact car tires litter the water column.

The Algalita Marine Research Foundation first visited the gyre 10 years ago, only to discover plastics outweighed zooplankton (the base of the food chain) by a ratio of 6 to 1. In a 2008 survey of the same area, that ratio had increased to 8 to 1.

Many of us have witnessed the sad state of our gutters and storm drains. It is this land-based debris that ultimately enters the ocean via rivers and drainage outlets. Of the trash found in the North Pacific Gyre, 80 percent originates on land. Some of this debris eventually breaks down. But the plastic debris is different.
