All animals and plants require clean air. In this book, children learn about why we need air, the value of wind, and the hazards of pollution and the greenhouse effect in Earth's atmosphere, and are told about efforts to reduce air pollution. The brightly illustrated " Taking Care of Your Planet " books were written and designed to help make young children aware that Earth's resources are limited and precious, and must be used with care. Each book tells a story that centers around children and their parents, as together they learn the value of conserving Earth's natural resources to help keep the planet green. Following each story, a four-page section suggests children's activities that relate to the book's central theme. A final two-page spread offers a guide for parents, with suggestions on how to use the concepts in the book to keep children aware of environmental issues. Color illustrations on every page.
