This book is designed to permit environmentally-conscious individuals to quantify the impact on the biosphere of their actions in the following areas: Home/household energy use; water use; transportation; consumerism (durable goods, foods and agricultural products, paper and forest products); toxics; waste, packaging, single-use items, and recycling; environmental advocacy; respect for the land; livelihood; family planning. EarthScore is based on an earlier computer software program called EnviroAccount (ordering information is provided), but the program is not required in order to use the book. A total of 107 questions are arranged in 14 sections. Questions are divided into Impact Questions and Action Questions. Scores are generated for each question, for each section, and for the entire questionnaire, with summary scores equated to various categories, e.g., Eco-Titan, Eco-Hero, etc. Most questions are followed by information as to why the question is important, how an individuals' performance can be improved, tips for change, and lists of relevant resources available to help the reader learn more about preserving the earth's resources for future generations.
