The subsidence of coastal Louisiana has nothing to do with plate tectonics. It is entirely man made. There are two main causes. The first is anti flooding programs on the Mississippi River caused the river to drop its sediment load up river and prevented the river from carring much of it down river to be deposited in the Mississippi delta area. Sediments naturally erode, compact and subside once deposited. When the river was carrying its natural sediment load deposition balanced subsidence, erosion and compaction. Now the delta erodes and settles faster than it is being replenished.
The second is withdrawal of natural gas and oil from their reservoirs cause the overlaying ground to settle.
Fair play, that makes sense.

If you describe yourself as “atheist,” some people will say, “Don’t you mean ‘agnostic’?” I have to reply that I really do mean atheist, I really do not believe that there is a god; in fact, I am convinced that there is not a god (a subtle difference). I see not a shred of evidence to suggest that there is one ... etc., etc. It’s easier to say that I am a radical atheist, just to signal that I really mean it, have thought about it a great deal, and that it’s an opinion I hold seriously." - Douglas Adams (and I echo the sentiment)
