Because a hunter like Walt Palmer is prepared to fly over and pay someone a large sum of money to kill a big, endangered critter, an economic opportunity attached to that critter is created. So, an enterprising individual will do anything from breeding to fostering to protecting and/or providing a habitat for a population of those critters. In order for that economic opportunity to last and for the investment to pay off, many more critters need to be added than the Walts of this world can ever kill. And because Walt and his pals want prime examples of that critter hanging on their trophy room walls, those critters need to be happy, healthy and wild. Yes, Walt will kill some of them, but many more will be able to go about their happy, healthy, wild lives as a result.
Yes, most of Walt’s spend does get pocketed by greedy capitalist types. But that’s the entire idea here. The greedy capitalist types are the ones earning a profit off the happy, healthy, wild population of critters. This isn’t some government boondoggle, it’s capitalism at its finest, creating employment and making the rich richer and all because they’ve got that happy, healthy population of critters.
