As photographers, we have a special appreciation for the landscapes, buildings and animals, as well as the people and cultures we encounter as we travel the world. For many of us, those are our subjects and may even provide our livelihood. Unfortunately, many species, places, cultures and buildings are under threat from development, neglect, disease, pollution and other perils. Here’s an area where we, as photographers, can make a difference. As a storytelling medium, photography (and videography) can educate, document, raise awareness and spur people to take action.
