A Tide of Trash

The recent storm-driven high tides have brought much more trash than I at first realized - but much of it is small pieces that ended up at the top of the beach. There seem to be 2 origins of this trash. First, like all the seas of the world, Long Island Sound has become a floating garbage dump a "sea-fill", where plastic bits break up and disperse, until unusually high tides deposit them back on land. Second the low dunes at the top of the beach seem to be made up partly of sand and partly of deposited trash. I suspect that over many decades people have been driving their bags of trash to the beach, and just tossing them behind the dune-line., probably because it was easier than taking them to the dump.
