What is the connection between environmental identity and diversity, equity, inclusion, and accessibility (DEIA+) work? The authors explore the intricate connection between these concepts and how aquaria are utilizing environmental identities to motivate pro-environmental behaviors in all museum visitors, including the identities of emerging museum audience. Using both literature and personal stories, the authors underscore how their diverse backgrounds and lived experiences were pivotal in the cultivation of their environmental identities, and how DEIA+ efforts bring more people and educators like them into the aquarium field. By centering diverse voices and stories, museums can create more inclusive experiences that resonate with broader audiences and thus expand their reach to more people with their messages.
