Martin Gray, world-class photographer and anthropologist, specializing in the study of sacred sites. Martin's travels have taken him to 1,000 sacred sites in 80 countries around the world. His journey unfolded in a remarkable compilation of images published in 2007 as Sacred Earth: Places of Peace and Power. Martin says, "Many ancient peoples had a reverential relationship with the living earth. If this can be reawakened and encouraged in our own culture, we will be better able to address the crisis of worldwide ecological degradation."
