I will assume, since you have been part of our community for a while, that I am not dialoguing with a troll. If you wish to give up hunting because you no longer wish to hunt, then that is a legitimate personal decision. I would note that if you are not giving up the consumpton of meat at the same time that you are on a slippery ethical slope. I am not sure what the difference is between shooting an animal yourself and paying someone to beat a cow in the head with a hammer. But again, putting up one's guns is a legitimate personal decision.
Where I differ, is the implied notion that your not hunting somehow will contribute to the survival of any species. Indeed, I think your decision has exactly the opposite effect. The only reason any huntable populations of game exist in Africa is because of the value they represent to the local population. In Tanzania, for instance, large amounts of dangerous game live in proximity to rural human populations. A lion, for instance, is an intollerable threat to a cattle herd unless he has a value of his own greater than the depravation he causes. Some PG competes with livestock and all of it is just so much protein without hunter generated value.
If we all were to put away our guns, I am absolutely certain that virtually all "wild" game would soon virtually disappear from the planet.
