This study investigates WhatsApp usage habits, focusing on media-sharing behaviors, storage practices, and sustainability awareness within the researchers’ networks, primarily Nigerians and Ghanaians residing in Morocco. With over two billion active users globally, WhatsApp has become a cornerstone of digital communication, enabling seamless connectivity across personal, professional, and societal domains. However, frequent media sharing, reliance on cloud backups, and insufficient storage management contribute to growing digital clutter and environmental impacts. Using a descriptive survey design, data was collected from 611 participants across diverse demographic groups. The data was analyzed using R, a powerful statistical software, to uncover trends and patterns in WhatsApp usage. The findings reveal significant levels of engagement, with 68% of users spending over three hours daily on the platform and actively participating in group communications. Media sharing emerged as a central activity, with 58% of participants frequently exchanging images, videos, and voice notes directly through WhatsApp. However, inconsistent storage practices, such as rare file deletion by 37% of participants and reliance on cloud backups by 74%, highlight gaps in sustainability awareness. These findings underscore the need for educational interventions and platform-level features that promote sustainable digital practices. By raising awareness of the environmental implications of digital behaviors and fostering responsible habits, platforms like WhatsApp can align their services with broader sustainability goals. This study provides actionable insights into balancing the convenience of digital communication with the imperative to minimize its environmental footprint.
