**A FINANCIAL TIMES BOOK OF THE YEAR 2022** 'Powerful... a clarion call for change', New Statesman 'Poetic and philosophical at times, intimate and expansive at others', Daily Telegraph How much light is too much light? The Darkness Manifesto urges us to cherish natural darkness for the sake of the environment, our own wellbeing, and all life on earth. The world's flora and fauna have evolved to operate in the natural cycle of day and night. But constant illumination has made light pollution a major issue. From space, our planet glows brightly, 24/7. By extending our day, we have forced out the inhabitants of the night and disrupted the circadian rhythms necessary to sustain all living things. Our cities' streetlamps and neon signs are altering entire ecosystems. Johan Ekloef encourages us to appreciate natural darkness and its unique benefits. He also writes passionately about the domino effect of damage we inflict by keeping the lights on: insects failing to reproduce; birds blinded and bewildered; bats starving as they wait in vain for insects that only come out in the dark. And humans can find that our hormones, weight and mental well-being are all impacted. Eye-opening and ultimately encouraging, The Darkness Manifesto offers simple steps that can benefit ourselves and the planet. The light bulb - long the symbol of progress - needs to be turned off. To ensure a bright future, we must embrace the darkness

This comprehensive book about the lives of bats is about a group of peculiar, mythical and fascinating animals. They are mammals, just like us, but still so different. The book covers bats from Latin American Maya temples to Swedish potato cellars; from the plains of Kenya to the Taiwanese mountains. We perceive their shadows flitting by in the summer nights, hear their mating calls in the darkness of autumn and see their silhouettes in the dim street light. The bats live in our houses and forage in our gardens and parks. But who are they and how do they lead their lives? The text and exquisite photos give an unsurpassed insight into the world of sounds and smells that bats encounter each night. We are told about how their senses, way beyond our human perception abilities, shape their lives. We get to know more about their habits, their long evolution and their cohabitation with humans, and how important they are to the environment. You will never again feel lonely in the darkness of the night.

How much light is too much light? The Darkness Manifesto urges us to cherish natural darkness for the sake of the environment, our own wellbeing, and all life on earth. The world's flora and fauna have evolved to operate in the natural cycle of day and night. But constant illumination has made light pollution a major issue. From space, our planet glows brightly, 24/7. By extending our day, we have forced out the inhabitants of the night and disrupted the circadian rhythms necessary to sustain all living things. Our cities' streetlamps and neon signs are altering entire ecosystems. As a devoted friend of the night, Johan Ekloef encourages us to appreciate natural darkness, its creatures, and its unique benefits. He ponders the beauties of the night sky, traces the paths of light-drunk moths and the dives of keen-eyed owls, and shows us the bioluminescent creatures of the deep oceans. He writes passionately about the domino effect of damage we inflict by keeping the lights on: insects failing to reproduce; birds blinded and bewildered; bats starving as they wait in vain for insects that only come out in the dark. For humans, light-induced sleep disturbances impact our hormones and weight, and can contribute to mental health problems. Eye-opening and ultimately encouraging, The Darkness Manifesto offers simple steps that can benefit ourselves and the planet. The light bulb - long the symbol of progress - needs to be turned off. To ensure a bright future, we must embrace the darkness.
