Meh, a woolly mammoth isn’t exactly going to escape and destroy Los Angeles like some kinda T-Rex. There’s a chick mentality out there that spends their life terrified of cool stuff like this.
Bring back the mammoth!
If anyone is real worried about them I can show them how to strike two special rocks together to produce a sharp edge.
It’s not fear of the Woolly Mammoth; it’s what comes afterward, resurrecting things and people who are better-off extinct, than alive.
Nefarious messing with DNA is a bad road to go down, yet much can be gained from constructive experimentation. All kinds of medical and life-betterment and extension achievements are possible.
I’d drop both that Mammoth and T-Rex with my .50cal, and BBQ them. I can’t imagine gutting, skinning and field-dressing that Mammoth or Rex, but you’re invited to help and eat your brains out.
