 beautiful natural morning at Cape Cod. But if you turn to the sea, you can see that the evening revelers were there. I've been to the beaches of Greenland, I've been to the beaches of Antarctica, and everywhere I've been, the flotsam and jetsam of humanity are on the beach. Oceanographers have traced the currents of the Pacific using shoes and rubber ducks that fell off of ships. More importantly, we have probably taken ninety percent of the big fish out of the ocean. We don't know what an ocean ecosystem should look like because it isn't natural anymore. We've changed the thing. We put so much fertilizer into the ocean in places from runoff, from farming, and pollution, and sewers that we cause huge poison blooms that essentially kill the life when they rot. And taking care of the ocean is a big deal.
