Can hunting save an endangered species? Yes. In Africa hunting has been critical to the conservation of a number of species, despite the sometimes opposition of the United States which can prohibit US citizens from hunting even in foreign countries.
I was surprised to discover, however, that “some exotic animal species that are endangered in Africa are thriving on ranches in Texas, where a limited number are hunted for a high price.” Texas hunters have saved several endangered African species, unfortunately for the animals, the story does not end happily.
