If cost quite a sum of money to feed an elephant.
If there is no profit to be made in owning an elephant very few private persons will own one. This leads to only one conclusion. Those persons currently owning an elephant for profit will either sell the elephants they own or dispose of them in some other fashion.
Given that the market for elephant is quite small and given the fact that their will be no profitable use for an elephant; it is inevitable that very few elephant will be sold as pets and a large fraction of the privately held elephants will be sold for pet food consumption.
So because the animal right organizations have put forth great effort to demonize the use of animals for human entertainment a good number elephants that could have lived long and productive lives will end up being food for Fido.
Good work you foolish idiots.
