Human activity often leaves a trail of harmful carbon behind that directly impacts our planet. This informative book describes how every individual produces a "carbon footprint" by using energy made by burning fossil fuels and by creating waste from packaging that gets thrown away. Find out how to measure your own carbon footprint and see what effect you are having on Earth. Learn about new developments being made to reduce the amount of carbon we create and what steps you can take to make your own "footprint" smaller.
