Sea walls stop waves and speed up the erosion beside them. Every fix moves a problem somewhere.

CREATIVITY
Every fix relocates something. A sea wall genuinely protects the beach behind it and sends the erosion down the coast to somebody who was not consulted, and most solutions have a version of this. You stop doing the group project work and it lands on one person. You cut a cost and somebody absorbs it. The fix is still real, and so is the place the problem went.
With your next solution, ask where the displaced part ends up. If it lands on a person, tell them before they find out on their own.
