"There's some who are greedy and some who don't care
they're poisoning our rivers & fouling the air
If all of the rest of us don't make them stop
They might end the life on the little blue top."

This song is clearly aimed at young children. Do we really think that it is good (good for the kid, I mean) to lay this kind of guilt and worry on somebody aged 4 to 10?

These are adult burdens.
