"Although thing have changed, hunting was a way of life for many people over many years. In order to survive, men and women had to track and kill their own food with spears, bows, knives and whatever else they could craft, purchase or find. Food did not come easily, and our ancestors appreciated what they had, though they sometimes went without due to failed expeditions. Scarcity like that forced the abandonment of camps, created homes and other types of shelters, as it was necessary to follow migrating food sources. Failure to do so would unfortunately result in starvation and disease – two sad things that history books tell tales of."
