We’d only need to exterminate three or four species of sharks and there would never be another attack on a human. That would include whites, hammerheads, tigers, and the bull shark. The balance of nature wouldn’t miss any of those any more than it misses the tyrannosaur.
No doubt there would be a project to
“Save the Tyrannosaur!” with little plush
stuffed tyrannosaurs and adopt-a-Saur bumper
stickers. People throwing themselves in front
of D-9s, and Harrassing Congressmen to “DO SOMETHING!”.
