"Some of the smallest animals have the mightiest powers. Big, brawny creatures may seem like the stars of the animal kingdom, but Earth's smallest inhabitants have impressive powers too. Ofter overlooked, these tiny critters help ecosystems thrive in numerous ways: they spread seeds, pollinate plants, make nutrient-rich soil -- or even become an essential meal for a predator. Gulp! Full of fascinating facts and information, Small but Mighty introduces readers to keystone, indicator, and other species that are critical to our planet's health, such as krill, honeybees, and reticulated glass frogs. And its message of environmental stewardship reminds us of the urgency to protect the teeny-tiny animals all around us. Whether we're big or small, our actions are mighty important too."--Back cover.
