There is a limited supply of freshwater on our planet. However, many people think that it is much easier to come by than it actually is. All living things depend on water and yet more than 1.1 billion people worldwide lack daily access to freshwater. Some water is contaminated with water-borne diseases and in some places such as the Sahara Desert there just simply isn't any water for people. This book explores the causes of the freshwater crisis and ways students can participate in being more mindful of water availability and their own personal water use.
