Losing southeast Louisiana

That's a stunning graphic. I had no idea SE Louisiana was THAT much of an ecological disaster!
What, if anything, can be done about this? The NOLA graphic suggests that levees are biggest culprit. But if you dismantle or stop building levees, don't you have to abandon New Orleans?

I don't mean to be uncompassionate, but at what point do we say, "Look. You guys are living on a flood-plain. You know that. We know that. You want to keep living there? Fine. That's your choice, but don't come crying to us when your house washes away." My heart really does go out to people who lost everything and my church and my family have and are doing their part to help out, but seriously, is anybody shocked when New Orleans (or Florida or Mississippi) is hit by a hurricane? For that very reason the help we've been focusing on up here is helping people permanently relocate somewhere else.

Ugh.. That whole Mississippi River situation is not a good thing then. There has to be an economical way to transfer goods from river barges to oceangoing vessels. New Orleans was founded as a port, to be that station of transfer where river boats and sea boats can come together to transfer things. Do we need to move the NO port operations to Pascagoula and set up fifteen parallel rail lines between there and Baton Rouge? In so doing, would we just abandon the Mississippi River delta and let nature take over? What makes other rivers different? Do they have this problem in Alexandria on the Nile? The Amazon doesn't have much trade going on along it. Are there similar circumstances with the Yellow River in China with all the silt it carries?
