Read an Excerpt

Day and night reveal two different worlds. For most people daytime is more familiar. Light makes us feel safe because we are most comfortable when we can see what is around us. Vision is our best sense and we rely on it.
In true night-time darkness, familiar landscapes change. The air feels different. Stars become visible. New sounds seem to emerge. The unknown creeps closer. It is natural to want to respond by turning on the lights.
People have only been able to turn on lights for just over 100 years. For the millions of years before that, animals and plants evolved in a cycle marked by both day and night. Our environment has not had enough time to adapt to light at night. And animals’ natural behaviors are being impacted in ways we are only beginning to understand.
The use of lighting has seemed harmless for a long time. Now scientists are discovering there is a cost to Earth’s ecosystems. As animals and plants suffer, people will experience consequences too.
