The Floating Plastic Gyre
I can specifically remember being told that we, as humans, needed to stop throwing shit into the oceans. That was in the 1970s, and it was not that long after a thing called Earth Day.
Apparently, we haven't been paying attention.
Someone, somewhere, needs to invent something that can go out in the ocean, suck up all of the plastic, and then turn it into magical ocean-renewing pixie dust. We need to turn loose a vast army of ships to go and clean up this mess and I can almost guarantee you, someone somewhere is smirking about how it's not really a problem and that Obama sucks! that's why.
