Garbage Island
Vice sails to the North Pacific Gyre, the collection point for all ocean flotsam and home to the Great Pacific Garbage Patch: a fabulous Texas island made entirely of our trash.
For as long as it has existed, the center of the gyre has been a naturally occurring rallying point for all the floating debris in one half of its ocean. Once afloat in the vortex, the flotsam is broken down (because until last century everything in the world was biodegradable) into a nutritious stew perfect for fish and smaller invertebrates.
The problem with plastic is that it will never fully dissolve unless you hammer it with enough pressure to create a diamond. Plastics photodegrade into individual polymers over time, but these little guys are still around for a long time. That means every synthetic molecule is still there, except for a few plastics specifically designed to biodegrade.
