Devotional Resources for Earth-Care
For earth-spirituality devotions, consider the book by Sam Hamilton-Poore (San Francisco Theological Seminary) Earth Gospel: A Guide to Prayer for God's Creation (Upper Room Books, 2008). The book offers prayers for morning, midday, and evening for every day for four weeks, supplemented with meditations, biblical texts, and prayerful reflection.
