A growing number of religious leaders are getting active in environmental issues, urging their congregations to be good stewards of the earth. This fall, leaders in 16 states have joined an interfaith effort aimed at educating people about climate change. Last year, a group of “Redwood Rabbis” fought to save old-growth trees in California’s Headwaters Forest, and next year eight Catholic bishops in Oregon, Washington, and British Columbia plan to issue a pastoral letter on caring for the Columbia River. “Our goal is to bring the mission of care for God’s creation more fully to the heart of religious life,” said Paul Gorman, head of the National Religious Partnership for the Environment, which brings together Roman Catholic, Jewish, Protestant, and evangelical Christian groups.
