Today's environmental movement seems to focus strongly on doing. There are things to buy, actions to take, petitions to sign, policies to advocate. It is rare for environmentalists to think of prayer as a tool for change. Many people in today's society think of prayer as a passive, contemplative activity -- a break from action. Jewish teachings express a very different view of prayer. Prayer is one of the key tools that God has given us to change the world. As we will see, it is our responsibility and opportunity to pray for the health of the earth and human civilization living on it and with it.
