From man to river to sea, our seas have become a plastic graveyard. About 90% of rubbish is plastic. The highest concentration of plastics can be found in the North Atlantic garbage patch, which receives most of its content from the United States, Canada, Mexico, and Europe. Remember the Malaysia Airlines Flight 370 plane search? There it was discovered huge swirls of plastic seen floating on the surface in the southern hemisphere along with what turned out to be discarded fishing equipment, cargo container parts an entangled plastic shopping bags. Around New Zealand and Australia its become a huge rubbish dump plus accumulating unseen plastic waste at the bottom of the ocean. Its not restricted to the southern hemisphere; most oceans have 'Garbage Patch zones'. The Pacific and Atlantic Oceans have two patches each, north and south. The Indian Ocean's garbage patch is centered roughly halfway between Africa and Australia.
I mentioned the idea of biodegradable's above in my original post, but what might also prove beneficial to our seas are plastics that decompose in the presence of salt? I'm sure this is not an original idea, but at least we know where most of it ends up - so for the sake of our planet, we should at least start thinking along such lines.
Hell, there might even be some money to be made of the clean-up...
