I have no misconception of isolation. I studied postgraduate marine biology before following the money into biotech, and have about a dozen friends in state environmental agencies.

There would be some consequences, but within limits. The earth wouldnt stop spinning and explode. There would likely be some marginal impact to migratory birds and local fishery, but it wouldn't cause mountainous in Tibet to go extinct or anything like that.

Anyways, Costal wetlands usually change constantly under natural conditions. Most of our static wetlands are already extremely unnatural, because cities and states have gone to great lengths to modify them in some ways and keep them from changing. They are about as natural as central park or a zoo.
