Jetsam

It is a moving midden, the ocean wide.
There may be monsters still inside.
In the waves, beneath the spray,
Stressed fish, krill and whales of gray.
But also something more
Tossed from ships and dumped from shore.
Flotsam we expect, but jetsam, some abhor.

Massive mats, offcast of man,
More, still more wide swaths they span.
Plastic foam and other junk,
"It's OK!" is a lot of bunk.
The bees on land are in decline.
"Roundup Ready®" is a clear sign
That man's dominion has not worked out fine.
