Generally trophy hunts are what provide the otherwise unavailable funds for conservation. Highlighting the harvesting of an animal is an easy way to get donations, but consider the effect of ceasing hunter funded conservation efforts. I highly doubt donations could come anywhere close to the revenue harvest licenses brings in.

Is it not in fact best to have the government incentivized to keep population levels sustainable? I fear a hunter-free Africa supported by donations would lead to excellent care of an increasingly smaller number of animals…which is unsustainable.
