There is a large part of the central Pacific Ocean that no one ever visits and only a few ever pass through. Sailors avoid it like the plague for it lacks the wind they need to sail Fishermen leave it alone because its lack of nutrients makes it an oceanic desert

For the last 50-odd years, every piece of plastic that has made it from our shores to the Pacific Ocean has been breaking down and accumulating in the central Pacific gyre. Oceanographers like Curtis Ebbesmeyer, the world's leading flotsam expert, refer to it as the great Pacific Garbage Patch.
The problem is that it is not a patch, it's the size of a continent, and it's filling up with floating plastic waste. My research has documented 6 pounds of plastic for every pound of plankton in this area.
My latest three-month round-trip research voyage, to be completed in Santa Barbara this week, got closer to the center of the garbage patch than before and found levels of plastic fragments that were far higher for hundreds of miles.
We spent weeks documenting the effects of what amounts to floating plastic sand of all sizes on the creatures that inhabit this area Our photographers captured images of jellyfish hopelessly entangled in frayed line, and transparent filter feeding organisms with colorful plastic fragments in their bellies.
As we drifted in the center of this system, doing underwater photography day and night, we began to realize what was happening A paper plate thrown overboard just stayed with us; there was no wind or current to move it away. This is where all those things that wash down rivers to the sea end up.
