i also think its a good management tool...its not like were ver going to see zo-bred elephants reintroduced to the wild, i hope things never get that bad, but developing this technology in zoos for use on wild populations is a good thing, and a way of exchanging genes between the two populations (in-situ and ex-situ)...
in captivity though there should be an emphasis on natural breeding too, as this obviously rcquires the correct social context, a goal as many elephant keeeping zoos as possible should realise...
