Scientists wanted to bring back the Woolly Mammoth.I thank it wouldn’t be good or safe because the Mammoth would destroy the world if it survives and if it doesn’t  than you just wasted a lot of money that you could spend to fight for canter.If it does survive than we are domed because it’s bigger than a elephant and it has longer tusk than elephant have.Also they have long fur and it’s so hot around hear that it would kill them.Pulse god took them out of the world for a reason and you don’t tire to bring back what god took out of the world or your will pay.
