Reading this as an Australian, where managing invasive species is a multi-million dollar problem, this is just...extraordinary.<p>> "It's just like this crazy wildlife experiment that we're left with," says San Diego University ecologist Rebecca Lewison. "Gosh! I hope this goes well."<p>You...hope this goes well? How about you shoot them all, while there's still a countable number of them? It's not like there's a conservation question here. There's almost no genetic diversity in the herd, and hippos aren't threatened in Africa.
