 We talked to an ecologist named Craig Packer about this. He led the Serengeti Lion Project for 35 years, and he said the lion swim was impressive, but unsurprising, given all that human and mating pressures these lions face in the park. And everyone we talked to just ultimately wants a better relationship between scientists and local communities to protect the lions and other wildlife, so they don't have to resort to journeys like this. That makes sense. So let's stick on Earth.
