Valderrama doesn’t recommend eating the meat, in case it is infected with a transmittable disease - one dead hippo was found to be carrying leptospirosis which can cause meningitis - but he does see the complete elimination of male hippos as the most practical solution.
Test the meat before eating, get your meningitis vaccines ...
True, if you eliminate all males, the females will eventually die of old age, issue gone. Or vice-versa.
I don’t know what he knows about infected meat, but that guy was one great midfielder. His passing and distributing of the ball was outstanding.
