How do photographers honor and draw inspiration from the natural world? How do aesthetics shape our understanding of ecological concerns?This issue features contributions by writers and photographers including Charlotte Cotton, T.J. Demos, Carolyn Drake, William Finnegan, Bill McKibben, Gideon Mendel, Aveek Sen, David Benjamin Sherry, Lieko Shiga, Thomas Struth, Bruno V. Roels, and Vasantha Yogananthan.
