A deep observation of coast and wetland, climate and self, by a leading Indian ecological activist. Introduction by Robert Macfarlane. Written in spellbinding prose, Intertidal reveals an unseen world. We hear frog calls through the night, spot butterflies miles into the ocean, see the churning of longshore currents, and meditate on worms' composting abilities. We also witness communities standing together to preserve the homes of the coast's inhabitants, both human and non-human. Intertidal asks us to reimagine values to live by; heeding the natural world, attending to the climate's calling, and moving away from the old political and cultural values that have proven ecologically disastrous. Set in beaches, marshes, and the wild places of the mind, Intertidal revels in the healing power of nature and explores what it means to reclaim an ecology that has been colonised.
