Herders, man, always getting the short end of the stick. Herding is a really good and interesting alternative to foraging and agriculture. You domesticate some animals and then you take them on the road with you. The advantages of herding are obvious. First, you get to be a cowboy. Also, animals provide meat and milk, but they also help out with shelter because they can provide wool and leather. The downside is that you have to move around a lot because your herd always needs new grass, which makes it hard to build cities, unless you are the Mongols.
