The most important part should be the emphasis on management of food sources vs. the carrying capacity of the deer herds. If we didn't hunt, then most of the population would starve to death as well as an incredible economic impact to humans with destruction of crops(you probably couldn't afford a salad without the killing of deer). One distinct example is the state hunt on Oak Mountain State Park in Birmingham Alabama this past year. This state park is about 10000 acres and it has a distinct browse line throughout the park. State officials knew that if some deer were not killed, then they would start dying off from starvation. The most important thing as a hunter is to realize that we are not Hunting just to kill, but to be a part of a bigger picture for the health of all deer herds in America. This is the reason for liberal bag limits in heavy population states with mild winters and low bag limits in states that have harch winters that increase herd kills. But if you search the web you will find some good statistics to back up your research and conclusions. Good luck!
