For thousands of years, reindeer herders have roamed the taiga of northern Mongolia.  The herders, know as the Tsachin, or Dukha, rely on their animals for transportation, and for the staples of their diet, milk, cheese, yogurt and dried milk curds.  But disease and inbreeding have reduce the herds from more than 2,000 in the 1970s to less than one-third of that today.  And that, in turn, has threatened the Tsachin's way of life.*
