I damn well know what's going on and it's mostly the fault of the overimpowered enviromentalist groups coupled with things like Levees.
Take a look at the Mississippi Delta for a second. How did it grow?
The river flooded and dumped all the mud from Iowa, Missouri and the like on it. The saltwater marshes grew up and out, some becomming purely
freshwater marshes, some becomming fully land.
Now the Levees are in place to protect cities like New Orleans. Fine, man doesn't want to be flooded out of his house every year.
Recently, to "protect the marshes" anything that the overimpowered enviromentalist decide that we aren't supposed to build up the land, the way the
Mississippi did before the environuts got a hold of law system.
Some of that land hasn't been marshland in over 80 years...if not closer to 200 years.
The parts of it that are still marshland don't get the major influx of Mississippi mud and while not sinking, are eroding away. (They can't sink at
the rate of a foot per year, like the environuts said, because our homes don't have a foot a year to lose. Gross exaduration. I'm some hour away
from the coast and I have maybe 5 ft elevation (not even). I have friends who have .5 ft., who'se grandparents had those same houses some 100 years
ago, and their elevation back then was .5 ft. It hasn't changed. Things like sinkholes occour with the currents, just like erosion. And while we
lose coast, it isn't from playing around with the marshes. Our hands are tied.)
Basically we can't fix the problem because of the environmental laws in place.
Now for the East coast. A few big natural issues that are supposed to happen can be happening.
1. A local watersource is bringing in mud, elevating the marsh above the saltwater. Drying out marsh becoming land has that same sick look because
the land is changing its general nature. If it's supposed to happen, as it supposed to happen, you leave it be. You'll be able to build a house
there in some 25 years without disturbing the marshland.
2. Another issue could be that the sea level is dropping either globally, or locally. As the global contradicts the
global-warming-melting-the-polar-icecaps, I'm all for it. I love irony, and anything similar. (Many rabid christians believe that God likes to make
us look like fools. All He'd have to do is melt the icecaps, but slow down the output of the fresh springs in the ocean to a lower rate than before
the icecaps were melting. He's been thumbing his nose at the weathermen recently, so might as well do the same with the icecaps.~Reference to when
the next Katrina was supposed to show up this year.) Even without a God, the chances of the Icecap Environuts being wrong are just as likely since
none of them were there the last time it happened.
Local would be more like natural levees (almsot strategic looking lumps of land) in the marsh giving way.....The whole marsh can't be under the
3. Freshwater intrusion. Look at the midwest....there's a whole waterway underground. Is there an underground waterway in that area for
freshwater? People had wells out there, in that general direction. If it changes underground course even a slight bit, the water may well be
brackish. Less salt can kill saltwater grasses. Nearly impossible to stop, since interfering with undergound waterways is what caused the Dustbowl
duirng the Great Depression. We don't know enough about them to deal with them.
...which leads to a manmade idea. Was there any new underground thigns put in that general area, like subways, sewer pipes? That changes the some of
where the underground water goes, if the water and the constuction is anywhere nearby each other.
4. Getting too hot and simmering the plants as the water evaporates in pockets. Happens down here all the time. Goes hand in hand with the first
one. It's easier to heat up small tiny pockets of water than a large mass.
5. Similar to 4: One loophole to building up the marshes is to burn them...or more accurately, when they burn, don't put them out. Why bother?
They are on water. They usually can't get far. When they burn, all the old material settles to the bottom, leaving room for all new plants instead
of having dead grass choke out the new plants. This builds up the marsh. This may be a natural variation on that. Kill out spots for the new grass
next season. It may just be that there's more spots than usual, this year. To test this one, the hole in the marsh would have to be studied for a
year or 5 even.
Most of this is some of those things that the environuts will mess with and screw up, all out of good intentions. Some of this is things that while
not out right harmful in the long run, are dangerous for the next 10 years, and needs to be checked into.
but seriously, I;ve seen pockets of marsh like that down here since I was a little girl, and now that I'm a gorwn man
Ive seen those same
patches of land recover without environut help.
