Humans can certainly extirpate just about any desirable species.
Sometimes we do it and don't even know it's happening.
We just don't see so many of those anymore. Then it's, "I haven't seen one of those in years..."
Any species that needs years to reach sexual maturity is a candidate. Like Great White Sharks.
When I was young, I prepped cod for lenten fish fries. Take a filet, cut it into servings size pieces, and check for bones.
They were 4 feet long, and 6" thick.
When's the last time anyone here ever saw a cod filet anything like that?
We are sifting the oceans with factory precision.
