Mar 5 2013: One of the difficulties conservationists encounter is that anything that restricts the supply of ivory will tend to increase the price, making poaching more attractive. Unfortunately (for elephants) the available evidence (and there is very little) suggests that people will still buy ivory, even if the price is high, as long as they have the income to do so. I offer an economic analysis of the issues and some links to the literature here http://worthwhile.typepad.com/worthwhile_canadian_initi/2013/03/can-evolution-save-the-elephant.html
