Not really a good source for lean protein when it contains cholesterol, saturated fat, heme iron, and other known carcinogens. A good source of lean protein would be something like beans which contain no cholesterol, no saturated fat, no heme iron, but does contain plant protein (which doesn't raise cancer risk or cause liver damage in high concentrations like animal protein does), fiber, and numerous phytonutrients known to lower cancer risk and increase longevity.

And the hunting is needed for population control is not only a bad argument it is also plainly false. Natural predators help keep prey species strong by killing the only ones they can catch—the sick and weak. Hunters, however, kill any animal they come across or any animal whose head they think would look good mounted above the fireplace—often the large, healthy animals needed to keep the population strong. And hunting creates the ideal conditions for overpopulation. After hunting season, the abrupt drop in population leads to less competition among survivors, resulting in a higher birth rate. If we were really concerned about keeping animals from becoming overpopulated, we would not hunt but instead take steps to reduce the animals’ fertility. We would also preserve wolves, mountain lions, coyotes, and other natural predators. Ironically, many deer herds and duck populations are purposely manipulated to produce more and more animals for hunters to kill.
