Paull Young, the new Environmental Sustainability lead at GitHub, explores the intersection of technology and environmental conservation through conversations with leaders from the Monterey Bay Aquarium Research Institute (MBARI) and Renewables.org. At MBARI, Principal Engineer Kakani Katija discusses the FathomNet project, which leverages open-source data and AI for ocean monitoring and conservation, and introduces FathomVerse, a mobile game designed to crowdsource image identification for research purposes. Meanwhile, Renewables.org co-founders Lassor Feasley and Scott Schwartz describe their online solar investing nonprofit that finances high-impact solar projects in the Global South, emphasizing the use of open-source methodologies to ensure transparency and maximize carbon impact per dollar. Both organizations highlight the cultural shift towards open-source data in environmental efforts, acknowledging its potential to democratize access and engage communities in sustainability initiatives.
