Drowning In Plastic The Great Pacific Garbage Patch
Image courtesy In t足he broad expanse of the northern Pacific Ocean, there exists the North Pacific Subtropical Gyre, a slowly moving, clockwise spiral of currents created by a high-pressure system of air currents. The area is an oceanic desert, filled with tiny phytoplankton but few big fish or mammals.
Worse still, there seems to be nothing we can do to clean it up. So how do we turn the tide? A shark carcase on Kamilo Beach, Hawaii, where plastic particles. Welcome to the Great Pacific Garbage Patch. Great Soils are the Key to Great Wines. Drowning in plastic.
Due to its lack of large fish and gentle breezes, fishermen and足 s足ailors rarely travel through the gyre. But the area is filled with something besides plankton: trash, millions of pounds of it, most of it plastic. It's the largest in the world, and it floats in the middle of the ocean.
The gyre has actually given birth to two large masses of ever-accumulating trash, known as the Western and Eastern Pacific Garbage Patches, sometimes collectively called the Great Pacific Garbage Patch. The Eastern Garbage Patch floats between Hawaii and California; scientists estimate its size as two times bigger than Texas source:. The Western Garbage Patch forms east of Japan and west of Hawaii. Each swirling mass of refuse is massive and collects trash from all over the world. The patches are connected by a thin 6,000-mile long current called the Subtropical Convergence Zone. Research flights showed that significant amounts of trash also accumulate in the Convergence Zone. The garbage patches present numerous hazards to marine life, fishing and tourism.

But before we discuss those, it's important to look at the role of plastic. Plastic constitutes 90 percent of all trash floating in the world's oceans source:. The United Nations Environment Program estimated in 2006 that every square mile of ocean hosts 46,000 pieces of floating plastic source:. In some areas, the amount of plastic outweighs the amount of plankton by a ratio of six to one. Of the more than 200 billion pounds of plastic the world produces each year, about 10 percent ends up in the ocean source:. Seventy percent of that eventually sinks, damaging life on the ocean floor source:.

The rest floats; much of it ends up in gyres and the massive garbage patches that form there, with some plastic eventually washing up on a distant shore.
