Seawalls impact a wide range of people, especially coastal communities, property owners, and marine ecosystems. Residents living near shorelines are directly affected when seawalls are constructed or fail, as these structures can alter natural water flow, leading to increased erosion in neighboring areas. Local economies that rely on tourism and fishing can also suffer, since seawalls often degrade beaches and coastal habitats. Additionally, ecosystems like wetlands and coral reefs, which depend on natural shoreline dynamics, are disrupted—threatening biodiversity and the livelihoods of those who depend on it.

What is at stake?
If the current approach to seawalls remains unchanged, we risk accelerating the degradation of our coastlines and losing vital ecosystems. Continued reliance on hard infrastructure can worsen erosion, displace communities, and reduce the natural protection that healthy coastlines provide against storms and rising seas. On the other hand, shifting toward more sustainable coastal defense methods—like living shorelines—could protect both human settlements and natural habitats. The future of our coasts, economies, and ecological balance hinges on how we respond now.

Why is now the time to act?
With rising sea levels and more frequent extreme weather events due to climate change, immediate action is critical. Delaying reform or adaptation in coastal protection strategies will only lead to greater damage and higher costs—both environmental and financial—in the long run. Now is the time to invest in smarter, nature-based solutions and reevaluate how and where we build seawalls to ensure that both people and the planet are protected for generations to come.
