The carbon footprint of the average American household is approximately 48 tons per year. The carbon footprint is the measurement of carbon dioxide produced in a given period of time. Carbon dioxide is produced in many ways, including the use of cars and electronic devices. The carbon footprint doesn't just affect wildlife, it also affects every person on the planet and every aspect of the environment. The carbon footprint can be reduced in several ways, for example by using energy-saving light bulbs. People need to help the environment and reduce their carbon footprint, otherwise they risk their health and well-being.
