Reports the New York Times:

Despite intensifying calls to ban or restrict trophy hunting in Africa after the killing of a lion named Cecil in Zimbabwe, most conservation groups, wildlife management experts and African governments support the practice as a way to maintain wildlife. Hunting, they contend, is part of a complex economy that has so far proven to be the most effective method of conservation, not only in Africa but around the world as well. ...

Lion hunts, one of the most lucrative forms of trophy hunting, bring in between $24,000 and $71,000 per outing on average across Africa, according to a 2012 study. In southern Africa, the emergence of a regulated trophy hunting industry on private game ranches in the 1960s helped restore vast stretches of degraded habitats and revive certain species, like the southern white rhinoceros, which had been hunted almost to extinction, conservationists say.
