 In such a frugal 1 environment, the Pika's farming helps to kickstart the food chain. But the Pika itself is a very tasty morsel 2. Its presence has enabled an uneasy relationship to develop between the two plateau most opportunistic predators 3, the fox and the bear. 


 
The Tibetan brown bear, a close relative of the grizzly 4, trys to dig the Pikas out from their burrows 5, even hard, frozen soil presents little obstacle to a determined 6 bear. The wily Tibetan fox is quick to spot any opputunity. True to form, the crafty 7 fox claims the prize. 
 
A combination of inaccessabily and ancient traditions, which forbid hunting, means that in some parts of the plateau, wild aninals have remained relatively 8 undisturbed, even today.
 
But in those areas which are within reach of motor vehicles, these historical safeguards have been undermined. 
 
These changes is illustrated 9 in the fortunes of the chiru. A century ago, millions migrated cross the plateau. Unfortunately, for the chiru, its fur, knowm as shartoosh ,or  King of wools,  is highly prized . In recent decades, purchase are being able to adventure deep into the wildness killing 10 thousands of chiru. however, the situation is improving, anti-poaching laws are now actively 11 enforced, so every summer female chiru can head to the birthing grounds in relative safety.
