Are mountains alive, like how trees and animals are? If they are, can they sense the destruction of the planet that is happening now, and help guide us? In this book, Godwin Vasanth Bosco presents ground-breaking evidence of these capacities existing in a remarkable mountainous landscape in India, called the Nilgiris. Based on nine years of in-depth research, Voice of a Sentient Highland captures the colossal story of the Nilgiris. Underlying geological processes are found working in volition, along with a myriad of plant ecological dynamics, to depict crucial patterns for the whole world. The story and explication of the stark patterns are woven together with images and illustrations into a rich visual narrative. The evidence presented is scientific, yet simple, and thus widely comprehensible. Vasanth finds that the voice of the mountain goes deeper than much of the current efforts for environmental and social change. Claiming that many of the `solutions' are inadequate and exacerbate decline, he translates this voice into five guides and solutions that are crucial for our collective future.
