Where to buy it


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.

About the author

Stephen Aitken is a biologist, artist and author.

He has written and illustrated many picture books, chapter books and close to a dozen nonfiction books for middle-grade readers, and he is the author of Saving the Night and Listen Up! in the Orca Footprints series. Stephen is the cofounder and executive secretary of Biodiversity Conservancy International and is the editorial director of the science journal Biodiversity.
