The search for mechanisms to encourage pro-environmental behavior has ranged from marketing to community events. This study continues the search by exploring how the language and features programmed into mobile social networking applications influence users to experience nature and share those experiences. To guide data analysis, the study uses the social influence network theory and adapts components of influence from the field of online social networking. One hundred posts, spanning almost two years, were analyzed from the Sierra Club's mobile Facebook page, Foursquare's Outdoors Raleigh search, and #Litterati's Instagram feed. Results point to the language and features that can help mobile application developers, government agencies, and environmental advocates to better design mobile apps for pro-environmental behavior. The author concludes with a call for more novel data uploading options outside of text, such as uploading video, creating music to represent nature experiences, or use of external sensors with mobile devices.
