Planet Ark: Preserving Earth's Biodiversity

Young readers can learn how to be modern-day Noahs and protect the world's plants and animals from extinction not by building a giant boat, but by making small changes in their everyday lives -- from planting trees to turning off the tap -- to help preserve the world's biodiversity. Planet Ark is part of CitizenKid, a collection of books that inform children about the world and inspire them to be better global citizens.
