The hot topics of global warming and environmental sustainability are concerns that fit neatly within the precepts of religious naturalism, according to Ursula Goodenough, Ph.D., professor of biology in Arts & Sciences at Washington University in St. Louis. In addition to being a renowned cell biologist, Goodenough is a religious naturalist and the author of The Sacred Depths of Nature, a bestselling book on religious naturalism that was published in 1998.
