I’m studying sustainable coastal resilience strategies in the face of climate change and rising sea levels. Seawalls don’t provide sufficient protection, harm wildlife, pollute waterways, and are difficult and expensive to maintain. Artificial walls don’t work in nature. What works is building longer buffet tables and larger homes that make accommodations for all stakeholders—coral reefs, mangroves, oyster beds, and salt marshes. This idea is much more than a metaphor or allegory. Seawalls are a cautionary tale of what happens when we exclude beings who have all the same rights that we do to survive and thrive. Sustainable solutions have successfully played out over the course of 3.8 billion years of natural history’s R&D lab. We would be wise to follow its example.
