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.
