Light and dark have affected the very ways humans, plants, and animals have grown and thrived. In fact, light and dark have affected pretty much the entire natural world around us. But lights from cars, streetlights, houses, shopping malls, skyscrapers, and other structures make towns and cities glow with light so bright it can be seen from outer space. What happens when humans tamper with the age-old balance of day and night?

Told through the eyes of thirteen-year-old Joan who loves the outdoors, Dark Matters introduces young readers to the fragile animals that are impacted by our increasingly threatened nighttime skies.

Come discover the amazing night life of frogs and bats, turtles and fireflies, birds, plants, and so much more. And learn how their lives and ecosystems are negatively impacted by light—much of which is so unnecessary.

This book is packed full with fascinating and unexpected facts and illustrations, and comes with tips and suggestions on how young people can help reduce light pollution.

Because dark matters!

Editorial Reviews

"I remember as a child being amazed at the sight of my first real night sky, undiluted by man-made light! The exhilarating beauty, complexity and infinity of the Universe, right there before my eyes. But, as Joan Marie Galat explains in this book, there is more to light pollution than its effect on star-gazing... the whole world needs dark skies!"— David Saint-Jacques, Canadian astronaut"A blend of fine storytelling and gripping facts, Dark Matters reveals the need for dark, along with its value to you and the world. A book to share—highly recommended."— David L. Crawford, Ph.D. (Astronomy) and International Dark-Sky Association (IDA) cofounder and former executive director
