While some countries are struggling to gain access to electricity, others are trying desperately to turn off the lights. Increasingly, we live in a world of "haves" and "have-nots" with regard to natural resources.
This week the International Dark-Sky Association (IDA), astronomy clubs, and a host of U.S. national parks across the country celebrate International Dark Sky Week to raise awareness of light pollution.
Washing away the wonders of our universe through light pollution is akin to barring access to our forests and oceans and canyons. It leaves us with fewer avenues to explore the natural world as it exists beyond our planet.
In New York, NYC Audubon has started the Lights Out NY program and has fostered agreements with corporations behind major buildings, like the Rockefeller Center and Chrysler Building, to turn their lights off at night during migration season.
Over the past century there has been a dramatic increase in the incidence of depression, sleep disorders and obesity. New data suggest that at least part of this increase could be due to the ever-growing exposure to light at night.
