We've severely overharvested Atlantic Bluefin stocks, and continue to do so, to satisfy the worldwide demand for this kind of fish. Bluefin are very long lived, and take a while to reach maturity, so our consumption is absolutely decimating the wild populations and killing the species before enough fish reach the right age to reproduce. If we give the fish time to recover, we can sustainably fish them, but they need 20+ years *National Geographic estimate, not mine* before we start catching them again.
