John C. Mack (born December 7, 1976) is an American artist, author, photographer, and founder of Life Calling. In 2021 Mack founded Life Calling, a not-for-profit organization aimed at helping society to live fulfilled lives in the digital age while retaining our humanity and personal autonomy. This is achieved through a diverse set of tools and activities, including, but not limited to, awareness campaigns, education, art, lectures, and programming. Among the initiatives is A Species Between Worlds: Our Nature, Our Screens (2022), an interactive photography exhibition that questions how a balance between our connection to nature and today’s growing device-dependence might be attained.
