A visual introduction to some of the problems facing our planet. This book includes everything needed for the projects shown in life-size illustrations, including the actual quantities required for immediate visual checking. A step-by-step method for every project is shown and accompanied by easy-to-follow instructions. The experiments are designed to help children understand what acid rain is, how air and water pollution affect the world and what "biodegradable" means. The topics of waste disposal, superflous packaging and the destruction of the rainforests are also covered. Young conservationists are shown how to create their own wildlife gardens, how to plant trees and how to make their own campaign badges, posters and leaflets.
