"A teacher challenges her class to decide which is the most important animal of all. Seven children champion a different animal for the top spot. Is it bees as master pollinators, or bats who are night-time predators as well as pollinators? Is it elephants who shape their landscapes and spread seeds, or beavers, who create watery habitats? Is it tigers or sharks who keep populations in balance so there is food for all? Is it tiny krill, food for so many whales and sea creatures? There is lots of information about them, and other keystone species, plus photographs to see them up close and in their habitats. This is a positive and gentle primer for young children from 5 years old about the issues of habitat loss, endangered species and climate change."-- Provided by publisher.
