I can agree with that .. cloning lost species .. however, where's the line ...? Where do we draw the line here though? Cuz they could be duplicating/replicating dinosaurs we speak .. and I don't know about you ... but cleaning up my doggie's poo is bad enough, without having a T-Rex crap on my back yard, lol
Cloning doesn't mean you're bringing back the actual animal which has departed. Cloning is replicating, and the 'copy' might have some of the same mannerisms, personality and characteristics, but it is not the previous form brought back to life here with us once again.
I agree, replicating is in theory good to help keep species alive that otherwise are endangered and potentially suffer extinction.
I wouldn't clone any of my deceased companions, personally.
