This timely and captivating look at the hidden impact of light
pollution is "rich in revelation and insight...lyrical" (The Wall
Street Journal) and urges us to cherish natural darkness for the
sake of the environment, our own well-being, and all life on earth.
How much light is too much light? Satellite pictures show our
planet as a brightly glowing orb, and in our era of constant
illumination, light pollution has become a major issue. The world's
flora and fauna have evolved to operate in the natural cycle of day
and night. But in the last 150 years, we have extended our day--and
in doing so have forced out the inhabitants of the night and
disrupted the circadian rhythms necessary to sustain all living
things, including ourselves. In this "well-researched and
surprisingly lyrical" (The New Statesman, UK) book, Swedish
conservationist Johan Eklöf urges us to appreciate natural
darkness, its creatures, and its unique benefits. He ponders the
beauties of the night sky, traces the errant paths of light-drunk
moths and the swift dives of keen-eyed owls, and shows us the
bioluminescent creatures of the deepest oceans. As a devoted friend
of the night, Eklöf reveals the startling domino effect of
diminishing darkness: insects, dumbfounded by streetlamps, failing
to reproduce; birds blinded and bewildered by artificial lights;
and 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 like chronic stress and depression. The streetlamps,
floodlights, and neon signs of cities are altering entire
ecosystems, and scientists are only just beginning to understand
their long-term effects. The light bulb--long the symbol of
progress and development--needs to be turned off.
"Urgent...vivid...eye-opening" (Publishers Weekly), and ultimately
encouraging, The Darkness Manifesto outlines simple steps that we
can take to benefit ourselves and the planet. In order to ensure a
bright future, we must embrace the darkness.
