Hunting is a sport that involves the use of firearms or other weapons such as archery equipment and other primitive equipment in the pursuit of wild animals or birds. It also can describe any activity that employs the use of these weapons for target shooting purposes, but is usually reserved for the pursuit and taking of wild game with weapons. Hunting is the primary means by which animal populations are kept within humane and manageable limits by the harvesting of a suitable percentage of the population to maintain a viable and healthy census of wildlife. Overpopulation results in disease, starvation, nuisance infiltration and unwanted human interaction. Hunting is an extremely important economical consideration as well as for game management purposes.
