The Eastern Himalaya -- land of Gods, of ancient mountain kingdoms, of icy peaks and alpine meadows -- is like no other place on Earth. The life and landscapes of the region are as diverse, spectacular, and fragile as the mountains themselves. Even today, these mountains hold many mysteries: unnamed species, primeval cultures, and the promise of magical cures to heal all of humanity. This book takes us on a journey of biocultural discovery -- from the great canyon of Yarlung Tsangpo and the Siang Gorge in the east to the Kali Ganda ki Gorge in the west. Along the way, the book demonstrates, in breathtaking imagery and words, why the preservation of this heritage is so important -- not just for us, but for the future of all life on Earth.
