The enormous stew of trash - which consists of 80 percent plastics and weighs some 3.5 million tons, say oceanographers - floats where few people ever travel, in a no-man's land between San Francisco and Hawaii.
The patch has been growing, along with ocean debris worldwide, tenfold every decade since the 1950s. The so-called 'Great Pacific Garbage Patch' - a heap of debris floating in the Pacific that's twice the size of Texas, according to marine biologists.
