Any solution to the climate change problem will almost have to involve the planting of millions of trees. Their ability to extract carbon dioxide from the atmosphere and turn it into cellulose is the simplest way to reduce the rising levels of carbon dioxide. Trees also provide valuable shelter for many species of animals and provide natural cooling in the form of shade and evaporation. This book explains the value of trees in the ecosystem at the level of the late elementary school child. The content is simple, yet complete, making it a valuable resource for the study of nature and climate change in the elementary school.
