Bacteria Could Help Stop Desertification
Bridgette Steffen writes "In attempt to slow down desertification, a student at London's Architectural Association has proposed a 6000 km sandstone wall that will not only act as a break across the Sahara Desert, but also serve as refugee shelter. Last fall it won first prize in the Holcim Foundation's Awards for Sustainable Construction, and will use bacteria to solidify the sandstone."
So basically, Bacillus Pasteurii will be used to actually turn the sand into sandstone instead of waiting for thousands of years or using other kinds of walls.
To be honest, the part which is more interesting is the fact that desertification will be stopped by using a wall. Sure, the Slashdot summary used bacteria as a hook, but in all honesty, the wall is more important than the bacteria anyway, which is why there's only a small mention of the bacteria in the source article.

It's what we do. We interfere with processes all the time.
I'm a big fan of interfering.
why exactly are we to interfer with this process?
Because moving the farmers would require something approaching socialism, and not moving the farmers would require something appraching starvation.
Moving the desert is a better choice.
The most information I could find is here (the full-size images are pretty large) and here.
It's hard to pick through the information, but is this scientifically viable? Or is this the random musings of an architecture student focusing only on the architecture side, and ignoring the biology side?
If our overlords are shitting out dung, no matter how useful, I'd prefer then to be underlords, or over-to-one-side-lords, or not-over-my-head-at-least-lords.

Nature is not "wise", and it is wrong to personify it or otherwise assume otherwise. All nature does is follow the path of least resistance.

There is no reason to argue with conservatives
Except it's usually the loopy lefty crunchy hippy types that actually most often anthropomorophize nature, assign it a personality, presume they know what it wants and how it should be, etc. You know it's true.
Don't disappoint your bird dog. Go to the range.
The vast majority of the sand is traveling very low to the ground. Sure, there's still a nice big dust cloud up high, but that big tall plume represents the least dense of the material, which is why it rises to the top.
You're essentially asking, "why have a sea wall if the very tops of the largest waves might still occasionally break over the top?"

Nonsense. You can't use atomics on shields, you can only use them on geological features. Otherwise the other great houses will obliterate you.

I was watching a program last night about the evolution of the planet, something about vulcanic activity and the superplume, and other things, as well as the evolution of the first landwalkers (tulogs?) that basically looked like a cross between crocodiles and fish, among all the changes in the environment, as well as mass ocean pollution (millions of years ago) killing a vast number of species.
When someone says nature is wise, they probably are romantizing how much "nature"/god? cares about our survival as a species but also don't want to be at the short end of the evolutionary stick when nature shows it' uncaring side and things change. I'm sure a man-made solutions to various things would be welcomed with open arms then.
Other invasive species that were intentionally introduced but are now wrecking havoc in the northwest include English Ivy, Himalayan Blackberry, and Californians.
I've abandoned my search for truth; now I'm just looking for some useful delusions.
Little googling revealed that bacteria could actually do it.
Bacterial cement However bacteria need nutrient (urine base btw) to do it. It may happens simple concrete could actually be cheaper.
I propose genetically engineering bacteria that turn sand into chocolate in an attempt to speed up dessertification, with a side effect of feeding starving refugees.

If our overlords are shitting out dung
Actually, we should start to worry if they start shitting out anything other than that. At the very least I'd say a trip to the doctor is in order.
Right, I understand that (and almost didn't say what I did, how I did..) but then again, what is balance in nature--what does that mean?
I don't think there is any (forgive the term) "natural" state which is the proper and balanced state. Everything in nature is constantly in flux. Sure, to use the common example of the predator-prey equilibrium, that is sometimes the case. Sometimes the predators go extinct, sometimes prey go extinct, sometimes they both do.
It seems to me that it's far easier to look at life on Earth through the lens of evolutionary bubbles and crashes. It only seems self correcting because we want to apply some kind of order to it, when it reality, that's just the way the universe works. When a forest fire burns, it burns everything it can, until it's burned too much and dies out. That seems about the same level of self correcting to me.
Where do they expect to get enough sand to build a wall 6000 km long?

That's just bullshit
