This essay represents a path toward integrating an interest in a healthcare profession, dentistry, with an interest in environmental sustainability. As an undergraduate student studying biology with an interest in becoming a dentist, I focused on courses required for health care professions. At my college, my academic major department implemented curricular changes that served to diversify environmental, ecological, and evolutionary course offerings beyond the traditional evolution lecture and ecology lab. As a result, I had the opportunity to enroll in an Urban Evolutionary Biology lecture course that explored the novel role cities play as evolutionary agents of change in natural populations over time (i.e., natural selection, migration, genetic drift, and mutation). The ability to interact with a professor of evolutionary ecology provided a space to cultivate new ideas of my own by integrating concepts from environment sustainability, specifically community-engaged research in biological science disciplines. Herein, I showcase the importance of learning outside one's comfort zone, contrast operational versus environmental explorations in sustainability, and share how metadata (data about data) in green dentistry can empower sustainable communities.
