If we hadn’t hunted beavers to extinction - for their fur, not because we feared they’d cause the end of the world - then children and beavers would have grown up together?
And children grow up in plenty of places with far more dangerous species, like dogs, crocodiles, hippos…
Theres a strong irony in saying you don’t like people “playing God”, when you’re heavily opposed to entrusting species that should have still been here. Surely you are the one playing God, by deciding that they shouldn’t be reintroduced?
