Bioluminescent animals make their own light to survive.

A firefly lights up the night sky, a foxfire mushroom sets the forest floor aglow and sea butterflies shine like beacons deep in the ocean. These glowing species are one of the most spectacular wonders of the natural world, and they are found on land, in the air and in the depths of the ocean.

In Living Light, discover how and why bioluminescent creatures glow, and what that special ability can tell scientists about how diseases such as cancer and malaria spread in humans. These light makers are facing threats from the effects of climate change, pollution and loss of habitat, and they need our protection. Young readers will learn how they can shine a light on bioluminescent species and use citizen science to conserve their habitats and keep these creatures glowing into the future.

Light pollution threatens the survival of every living species on our planet, including people.

It started when Thomas Edison invented the first light bulb more than 150 years ago. Then, as electric light became more common, light pollution began to take over cities and towns. Today, in urban centers all over the world, the stars in the sky aren't visible. Millions of people have never seen the Milky Way. In Saving the Night, we discover how plants and animals have adapted over millions of years to survive and thrive in the dark, and how artificial light can upset the balance of entire ecosystems. But there are ways we can take back the night for animals, plants and us. It starts with the flick of a switch.

The sounds of nature are being drowned out by the clamor of human activity, and that's not good for people, animals or the environment.

Every living thing emits sound--birds sing, whales whistle, streams burble and trees pop and fizzle. In Listen Up, young readers are introduced to all the sounds of the natural world, from the first Big Bang to the complex soundscapes of the rainforests.

Readers will also discover how the invasion of human sounds, from airplanes, traffic and machines, is threatening the survival of species that have adapted to their habitats over thousands of years. Conserving the sounds of nature is an important part of addressing the biggest challenges facing humanity today--protecting the planet's biodiversity and the future of our natural world.
