Yes, an apple core or banana peel is biodegradable.
But starting in 3rd grade, we were taught to
not LITTER,
not to pick and choose what would rot or be taken away by animals.
We were taught "No Littering", period.
And we were held to that rule and highway laws all the way thru school and until.....
.....we got to the Me, Me, Me Era:
"It's all about me. If you don't like my litter, then YOU pick it up."
Problem is, we're not third graders. We're supposed to be grown-ups.
