Imagine a world where giant elephant-like beasts roam the vast plains of North America.
Perhaps someday this will be more than a long-lost memory. Perhaps within our lifetimes we will see this for ourselves.
An effort is currently underway to extract the DNA from a preserved woolly mammoth carcass, inject it into the living egg of a living elephant, and clone the long-extinct beast.
I don't have to point out how good of an idea this is.
Preferably, once the revived trunk enthusiasts have a viable breeding population, they can be re-introduced into the wild, so that they might reclaim their place in the food chain.
