From evolution to capitalism, ‘survival of the fittest’ has shaped our view of the world. But we got it wrong – and our mistake has brought us to the brink. For the history of life on Earth is much more than a story of competition. The natural world has been forged and sustained by small miracles of co-operation between animals and plants, insects and fungi, fish and bacteria – these partnerships are ubiquitous, lifelong and are an essential guide for a better future. In ‘Togetherness’, Rowan Hooper reveals the intimate connectedness of nature through these remarkable stories of symbiosis. From the female wasp venturing deep inside a fig and the intricate relationship between corals and the algae that sustain them to the symbiotic gut microbes that influence our moods, he explores how co-operation is fundamental to life itself and to protecting our shared future.
