I want elephants to return to London (i know it will never, in a million years happen)
But ovbiously they can't go in their old envlosure as it's a bit too small for a full herd of elephants, but i suppose if the zoo extends into regents park they could build a fantastic elephant habitat.
Unfortunately, the chance of the zoo expanding into Regent's Park is practically nil, this was just something they were discussing a few years back.
By the way, why is it always elephants? I would be just as happy to watch an active group of coati in a small city zoo (and they would probably be better cared for).
