@nixCraft Without a significant gene pool of members, around a thousand or so, you are simply using a creature for your personal entertainment and dooming them to extinction again.
@nixCraft Hrm. Big Hollywood movie title: Mammoth Park.
There's a park full of cloned mammoths, but they had to replace some of the DNA with elephant genetics, for the sake of diversity and a breeding population.
The mammoths soon get out of control and begin rampaging around the place, because an elephant never forgets all the horrible things the human race has done to them in the name of science!
