Use this interactive online calculator to determine the extent of your use of natural resources, including your carbon footprint, use of land, water, and trees based on your responses to a series of questions about your lifestyle and behavior. Students can compare their "footprint" to the average in several nations. There is a brief explanation of each "footprint" and an accompanying letter to parents and teachers (downloadable). Even adults will be interested in measuring their own impact on the environment.
