There was a time here when tribal Tibetans roamed across a vast dramatic landscape with no specific place to call home.For generation after generation they had lived as nomads, sleeping where they made camp.They kept their livestock moving, chasing the fresh pastures that became available as the seasons changed.The limits of their territory were identified by mountains and rivers, and their nomadic existence permeated all aspects of their culture.In 2016, you might expect this lifestyle to have been fully extinguished, yet it hasn’t been. Not quite. However, what’s left of it is now coming under considerable pressure.[Source]
