I am a nomadic artist.

Nomadic hunters bring down rabbits, gathering food.

You're really rubbing shoulders with the world's last great nomadic people.

In Mongolia for instance, where 30 percent of the people are nomadic,

How far will our nomadic species have wandered by the end of the next century?

And I learned about profit and revenue, about leverage, all sorts of things, from farmers, from seamstresses, from goat herders.

So I would hear from goat herders who had used that money that they had received to buy a few more goats.

In any case, populations grew and pretty soon, growing families in these villages became less suited to the nomadic lifestyle.

We flew to Pevek, the northern most city in Russia, and from there we went on to visit the reindeer herders in Tundra.

And we see these families, these nomadic families, you know, father to son, father to son, and these guys are hurting.

It would destroy riparian forests, which were the basis for the survival of nomadic groups, the Samburu and the Turkana in this area.

But there were these beautiful details, even if I talked to 20 goat herders in a row, and some days that's what happened these beautiful details of life change that were meaningful to them.

Now, the interesting part comes in more recently when anthropologists began taking this game to other cultures and discovered, to their surprise, that slash and burn agriculturalists in the Amazon or nomadic pastoralists in Central Asia or a dozen different cultures each had radically different ideas of what is fair.
