Why is pastoralism important?

Pastoral farming is focused on producing livestock animals like cows, chickens and goats as opposed to crop farming. Recent trends in livestock farming have focused on free-range techniques that allow animals to roam a larger area, similar to their ancestors who traveled as part of nomadic tribes. It is widely believed that free range pastoral farming is more healthy and humane to the animal, leading to longer lives and higher quality meats, eggs, milk and other products.
