The Great Pacific Garbage Patch- there is an area in the North Pacific ocean gyre where humanity's refuse collects. This area is about the size of the US state of Texas, but it could be much larger. Due to ocean currents (the Horse latitudes, or 'doldrums') this garbage collects in a more or less stationary zone. The patch is mostly flotsam from land sources- plastics, etc. The patch descends about 300 feet beneath the waves, and the individual pieces of trash are usually so small that taking a dramatic photograph of the mass cannot be done. Animals eat the plastics, which becomes a false synthetic estrogen; so now the Ocean creatures are deformed and unhealthy, the poisons are in the food chain.
