The Unabridged firefly: Stink up the River

I was sitting by a river when the thought occurred to me
That there are hardly any rivers left not clogged with our debris.
There are many things that you can do to make the problem worse,
And I have written some suggestions,
(set conveniently in verse).

You’ve got trash and you’ve got garbage, and the odor’s getting rife.
It’s just the ultimate result of our consumptive way of life.
So when the dump yards of your land are full of inconvenient gunk,
You’ve got to stink up the river with all your junk.

For all through our race’s history, we’ve fouled the streams we drink.
You know it isn’t any mystery which species caused the stink.
And it’s not a new invention; it goes back to Stone Age Man.
It was at least a million years ago waste management began.

When one day a certain caveman found a way to clean his cave
Without attracting hungry carnivores with bones that they would crave.
He just chucked ’em in the river, and they landed with a plunk.
He had to stink up the river with all his junk.
