Toxic: Garbage Island
For years we've been reading about a patch of garbage the size of Texas floating in the middle of the Pacific Ocean, ingeniously dubbed the Great Pacific Garbage Patch. Basically, any trash that gets dumped in the water rides the currents to this one spot and joins an ever-increasing flotilla of garbage. For all the breathless accounts of the mess and its impact on the area's sealife, however, no one seemed to have a picture of the buildup.
In order to sate our own curiosit
