Liberals blame human beings for global warming and the subsequent rise in sea level. Whatever, weather occurs. But even the non-sophisticated Native Americans intuitively knew not to build or live year round on a barrier island. By design, they change. It's part of the natural system. They migrate and they absorb storm energy protecting the mainland. They can and have been breached and are subject to complete wash-over. Bulkheads, pumps and walls are just a temporary band-aid.
