Ocean acidification (OA) is one of the most imposing, yet still misunderstood, threats to our coasts. Even within aquariums, it can be hard to find detailed information about OA. This is a huge missed opportunity, especially as aquariums serve as one of the best places to not only educate people on marine issues, but also center issues in the affected communities. Indeed, the clock is ticking: OA is already becoming increasingly devastating ecologically, economically, and culturally. Yet, there is still an opportunity to mitigate much of the worst effects … if we act now. Thus, to enable equitable and sustainable change, it is vital to connect with people through OA communication that engages and empowers people to take action, especially in the most at-risk regions.
