Save the Wildlife! Use Viagra!

Asian men are switching to the blue pill to cure their impotence, meaning they can now put away their sliced deer antlers, seal penises, seahorses, green turtle eggs and bear gall bladders, thus saving the wildlife population.
Chinese men are said to be "deeply suspicious" of Western medicine, and will only trade in their animal cures "unless they have a very good reason."
I don't think insurance covers seal penises. There's another bonus for making the switch.
