Ten founders are leveraging coding to address global sustainability and environmental challenges through innovative apps and games. These initiatives aim to foster environmental careers, preserve indigenous knowledge, and enhance nature education. One example is the BoRa app, which gamifies park visits with interactive storytelling and accessibility features, creating deeper connections with nature. Another is CyberTracker, an app that digitizes the tracking expertise of indigenous peoples using an icon-based interface. This preserves vital biodiversity data and supports global conservation efforts. Earth5R, a platform developed by Bharati and Saurabh, provides environmental education and career development opportunities. It connects users with internships and projects, building a skilled workforce for the green economy. These founders are actively contributing to a healthier planet through technology. Their work highlights the power of coding in driving environmental solutions. The #WeArePlay initiative showcases these global changemakers.
