But...but...Fred Flintstone caused the extinction of the dinosaurs, not the mammoths!
Fred was always wolfing down Brontosaurus-burgers.
Except...one night a brain-addled Fred was singing Italian opera. Betty Rubble heard the loud cacophony & said to Barney, “Some poor mastodon must be stuck in the tar pits!”
And that mining he did at Mr. Slate’s quarry damaged the environment.
