The Darkness Manifesto

How light pollution threatens the ancient rhythms of life

An enthralling and original encounter with darkness - and the secret, vital world within it

The Darkness Manifesto urges us to cherish darkness for the sake of the environment, our own wellbeing, and all life on earth.

Entire ecosystems rely on natural darkness to flourish, from bats and keen-eyed owls capering across the starry sky to the bioluminescent creatures of the deep. But constant illumination has made light pollution a major threat. By extending our day, humans have disrupted the circadian rhythms necessary to sustain all living things.

The Darkness Manifesto lifts night's veil to reveal the domino effect of damage we inflict by keeping the lights on: insects failing to reproduce, plants left unpollinated, countless hunting and migratory patterns eroded. Eye-opening and ultimately encouraging, this book offers simple steps that can benefit ourselves and the planet.

Daily Telegraph

Accessible, fascinating, and stimulating [...] acts as a siren call for anyone who is concerned about the affect of humanity on our environment. The Darkness Manifesto opens eyes, hearts, and minds to beauty of darkness, and the importance of its continued existence


Powerful ... Eklöf [shows] it is time for us to re-embrace darkness, both for nature's sake and our own


Eklöf underlines that only a fraction of outdoor artificial light benefits us... It is time for us all to re-embrace darkness, both for nature's sake and our own


A pleasure to read [and] a paean of praise for natural darkness in its own right

Financial Times *Best Books of 2022: Science*

Eklöf lays out the psychology, philosophy and politics behind the spread of illumination. Embracing the darkness isn't going to be easy ... Thankfully, Eklöf's last chapter is a manifesto of actionable points to befriend darkness [and] do our bit to try to save this spottily, but still too brightly, lit planet

New Scientist

Eklöf expresses his fears with cogent clarity in The Darkness Manifesto ... [and] takes his argument around the world [with] a style that is sometimes elegiac and often urgent ... the world needs to accelerate its embrace of darkness. To quote Eklöf's concluding phrase, carpe noctem
