Well, we could just euthanize the mammoth. These concerns didn't stop us from cloning dolly, or doing hundreds of other genetic experiments. Or millions of other instances of animal testing.
On the eve of being able to reverse extinction itself, the progressive/environmentalist/animal-rights-advocates crawled so far up their own asses that it became morally unacceptable to even try.
You can't make this shit up, it's absolutely hilarious.
Fools laugh at what they don't understand. To begin with, a formal debate requires exploring arguments against the proposition for the side that is assigned to oppose it.
Of all the extinct species you might attempt to resurrect, a mammoth is about the least economical option because when things go wrong (as they do) every problem will be massively expensive. If it gets born successfully but develops a health problem that requires surgery of some sort? $10,000 minimum. There will likely be a string of very expensive problems.
Maybe it would be wiser to start with something a little more manageable, like an extinct dog breed - we understand dogs better than we do elephants, for obvious reasons. There's a long list of extinct animals, most of which are a lot more manageable than woolly mammoths: https://en.wikipedia.org/wiki/Lists_of_extinct_species
