A former emergency room physician, Dr. Matthew Sleeth felt like he was straightening deck chairs on the Titanic saving a patient at a time while the whole ship (Earth) was going down. Together with his wife and two children, he began to bring his lifestyle in line with his values, cutting back on their fossil fuel by two thirds and electricity use by nine tenths. Following a new calling, Dr. Sleeth resigned from his position as chief of the medical staff and director of the ER to teach, preach, and write about faith and the environment throughout the country. Dr. Sleeth is a graduate of George Washington University School of Medicine and has two post-doctoral fellowships. He is the author of Serve God, Save the Planet: A Christian Call to Action (Zondervan, April 2007), the introduction to the Green Bible (2008, HarperOne), and 24/6: A Prescription for a Healthier, Happier Life.
