In a symbolic gesture against poaching, Kenyan President Daniel arap Moi burned 2,500 elephant tusks. Does this make sense from an economic standpoint? Using a graph, illustrate the effect of this burn on the quantity of tusks supplied illegally by poachers, assuming that the 2,500 burned tusks would otherwise have been on the market legally, and that the remaining supply comes from poachers. How would your answer change if worldwide media coverage of the event dissuaded potential consumers of ivory?
