there are many areas that are inundated with Pachyderms and are legally hunted. It is a necessity is some parts of Africa.
Check your facts.
It is true that elephants are a problem in some parts of Africa. They must be harvested, as in Kruger Park. However, experience has shown that killing individual elephants in a herd terrifies and deeply disturbs the others (who are, after all, the relatives).
Hunters who must thin the population in Kruger now take whole family groups at a time. The hunters are professional, and know what they are doing. Most of them respect the wildlife, and go for a clean kill with high-powered rifles, not minimal toys like that bow-and-arrow, which probably left the animal-victim to bleed to death overnight while her killer was snoozing comfortably.
The meat of the culled elephants is processed, and sold. If you visit there, you can have elephant burgers for lunch. The meat is very low in fat, and somewhat dry: not up to beef or impala, in my opinion, but it should not be wasted.
Looking at it from the girl’s viewpoint, she would have learned much more watching these animals than shooting them. The hunter never sees as much as the observer with a camera: of that I am sure. Furthermore, it is far more exciting to confront wild animals with only a camera, than armed with a lethal weapon. I have been charged by an elephant, and by a hippo, and have lain in the grass 20 feet from a rhino. There is nothing like an element of danger to get the adrenalin going.
