This month, an investigative report by Bryan Christy implicates organized religion in the demand for illegal ivory. In addition, leaves are profiled…how did they evolve and why do they look the way they do? Photographer David Alan Harvey takes us into Rio de Janeiro as it prepares to host the 2016 Olympics. Central America’s Mesoamerican Reef and its remarkable eco-region are explored, as are cliffside caves in Nepal’s Mustang region. A photo piece on the animal squatters of a rural Finnish town is included.
