The ancient Egyptians left behind the pyramids and the Romans, the Colosseum. What will our monument to history be?
It could be a stadium or a mall.
It could be one of our actual monuments.
It could be the swirling vortex of trash, leftover plastic tabs, and bits of shopping bags that make up the Pacific Garbage Patch.
Whatever it is, tell us in the comments (with a picture, please!) what future generations will know us by.
