Adapted from Paul Bogard, “Let There Be Dark.” ©2012 by Los Angeles Times.

Originally published December 21, 2012.

At my family’s cabin on a Minnesota lake, I knew woods so dark that my hands

disappeared before my eyes. I knew night skies in which meteors left smoky

trails across sugary spreads of stars. But now, when 8 of 10 children born in

the United States will never know a sky dark enough for the Milky Way, I worry

we are rapidly losing night’s natural darkness before realizing its worth. This

winter solstice, as we cheer the days’ gradual movement back toward light, let

us also remember the irreplaceable value of darkness.

All life evolved to the steady rhythm of bright days and dark nights. Today,

though, when we feel the closeness of nightfall, we reach quickly for a light

switch. And too little darkness, meaning too much artificial light at night,

spells trouble for all.

Already the World Health Organization classifies working the night shift as a

probable human carcinogen, and the American Medical Association has voiced its

unanimous support for “light pollution reduction efforts and glare reduction

efforts at both the national and state levels.” Our bodies need darkness to

produce the hormone melatonin, which keeps certain cancers from developing, and

our bodies need darkness for sleep. Sleep disorders have been linked to

diabetes, obesity, cardiovascular disease and depression, and recent research

suggests one main cause of “short sleep” is “long light.” Whether we work at

night or simply take our tablets, notebooks and smartphones to bed, there isn’t

a place for this much artificial light in our lives.

The rest of the world depends on darkness as well, including nocturnal and

crepuscular species of birds, insects, mammals, fish and reptiles. Some examples

are well known—the 400 species of birds that migrate at night in North America,

the sea turtles that come ashore to lay their eggs—and some are not, such as the

bats that save American farmers billions in pest control and the moths that

pollinate 80% of the world’s flora. Ecological light pollution is like the

bulldozer of the night, wrecking habitat and disrupting ecosystems several

billion years in the making. Simply put, without darkness, Earth’s ecology would

collapse....

In today’s crowded, louder, more fast-paced world, night’s darkness can

provide solitude, quiet and stillness, qualities increasingly in short supply.

Every religious tradition has considered darkness invaluable for a soulful life,

and the chance to witness the universe has inspired artists, philosophers and

everyday stargazers since time began. In a world awash with electric light...how

would Van Gogh have given the world his “Starry Night”? Who knows what this

vision of the night sky might inspire in each of us, in our children or

grandchildren?

Yet all over the world, our nights are growing brighter. In the United States

and Western Europe, the amount of light in the sky increases an average of about

6% every year. Computer images of the United States at night, based on NASA

photographs, show that what was a very dark country as recently as the 1950s is

now nearly covered with a blanket of light. Much of this light is wasted energy,

which means wasted dollars. Those of us over 35 are perhaps among the last

generation to have known truly dark nights. Even the northern lake where I was

lucky to spend my summers has seen its darkness diminish.

It doesn’t have to be this way. Light pollution is readily within our ability

to solve, using new lighting technologies and shielding existing lights.

Already, many cities and towns across North America and Europe are changing to

LED streetlights, which offer dramatic possibilities for controlling wasted

light. Other communities are finding success with simply turning off portions of

their public lighting after midnight. Even Paris, the famed “city of light,”

which already turns off its monument lighting after 1 a.m., will this summer

start to require its shops, offices and public buildings to turn off lights

after 2 a.m. Though primarily designed to save energy, such reductions in light

will also go far in addressing light pollution. But we will never truly address

the problem of light pollution until we become aware of the irreplaceable value

and beauty of the darkness we are losing.

Write an essay in which you explain how Paul Bogard builds an argument to

persuade his audience that natural darkness should be preserved. In your essay,

analyze how Bogard uses one or more of the features in the directions that

precede the passage (or features of your own choice) to strengthen the logic and

persuasiveness of his argument. Be sure that your analysis focuses on the most

relevant features of the passage.

Your essay should not explain whether you agree with Bogard’s claims, but

rather explain how Bogard builds an argument to persuade his audience.
