What is the role of the nomads in the economy?

The nomads' economy is, on one level, simple. Households raise sheep, goats, and yak under a "natural" system of pastoral production. Their livestock are not fed any specially sown fodder plants or grains, and survive exclusively by grazing on range forage.

This can be very tricky however, because if they were to settle somewhere with higher altitude, that would pose a problem, as there would be a very short growing season.  I hope this helps!

ok, so basically your gonna start with 350 ok. so there's 60 seconds in a minute so that means you he can go up 10 ft per minute. soo, after 3 minutes he should be at 260 ft after three minutes : )
