We don't remember the dust bowl.

One of the problems of agriculture in China, is that their topsoil
is being blown into the air, to land on Japan and in the oceans.
Japan has been having beautiful sunsets because of this phenomenon

The problem with agricultural topsoil loss, is that it takes
a long time to replace:

It takes 500 years to replace 1 inch of topsoil In a natural
environment, topsoil is built up by decaying plant matter and
weathering rock, and it is protected from erosion by growing plants.
In soil made susceptible by agriculture, erosion is reducing
productivity up to 65% each year. Former prairie lands, which
constitute the bread basket of the United States, have lost one half
of their topsoil after farming for about 100 years. This soil is
eroding 30 times faster than the natural formation rate. Food crops
are much hungrier than the natural grasses that once covered the Great
Plains. As a result, the remaining topsoil is increasingly depleted of
nutrients. Soil erosion and mineral depletion removes about $20
billion worth of plant nutrients from U.S.

When the Conquistadors entered that part of the (now)
American Southwest, they wrote about grass too thick
to walk through, stirrup-high on a mounted rider.
Overgrazing gave us the wasteland we see now, which
nearly everyone mistakes for the natural desert terrain.
You seldom see the cattle - it takes acres per head to
sustain beef cattle - but if you look at the fence lines,
you see what the land might look like without them.

There's desert, and then there's desert.

The story is the same all over. I remember reading of a plantation owner
in the Carolina's in the early days of this country. He spoke of cotton
as high as a man on horseback. But the soil is now depleted and will not
support that kind of growth. Th only way anymore to get sustained yield
is to add back through chemical fertilizer that which was taken in the
past. It is a poor substitute and pushes everything out of balance. But
this kind of cotton is no more. To many mis-adventures by man.

In the early days of explorations naturalists passing through Alabama
wrote of what is now the Alabama River, and seeing a whitewater wave
rushing upriver - but as it got closer it could be seen that it was huge
shoals of fish - and behind them was alligators rushing into feed. But
no more. To many mis-adventures by man.

In my own experience in 30 years of living in Alaska, in the beginning
salmon would be so thick in the creeks you cuold walk across on their
backs practically. But no more. To many mis-adventures by man.

In the plains states thee were great herds of buffalo with grasse to
support them, but no more. To many misadventures by man.

The slow churning of the land into a morasse of ground that nothing can
live on continues. We may be STARTING to get the message - we must be
good stewards of the land. The old principle of "Conquering the
Wilderness" was fallacy, and we have pretty much lost paradise as a
consequence.

I am reminded of an early lesson learned when viewing a bacterial colony
growing in the middle of a petri dish. It grew and grew and grew -
consuming everything in site, and as it did so, it's own poisons began
to kill it in the center, but there was still plenty of food - but soon
enough - it reached the limits of it's environment - all the food was
consumed, and it's own waste and starvation killed it. A strong lesson.

We had best learn how to be good stewards, and get in step with nature,
instead of struggling against nature - lest we suffer a similar fate as
the bacterial colony.

Cyclic thinking, rather than linear thinking.
Understanding, rather than "mastering." And there ain't no free
lunch.

Hi John,



Quite so...


And quite so here in Las Vegas in it's way.


Water was and remains crucial to the life styles of the population here.


Rather, wasting Water, and, wasting the Land and wasting everything, in
every manner possible, and being patronized for it, by others who make mone=
y
for it being patronized, is.


Where once were Artesian Springs, Deer, Ducks, Migrating Birds' dally, clea=
n
Air, clean wholesome Water...now
are the grainy concrete and asphalt malls and other seemingly endless
developments and their in-effect, sterile and deadening over-lay...and
Tap-Water so bad you will get nauseous and dizzy if you drink it.

A few blocks from me, used to be large open Truck Gardens which supplied
fresh produce for the Town in the 1930s through early 1950s...all gone now,
without-a-trace...everything brought in, instead.

Small Orchards, small Vineyards, and Backyard Vegetable Gardens were a
ubiquity here till the 1960s...now, no one I know knows of anyone who has
any sort of Garden or other cultivation.


Anyway...


...sigh...


Here's a little Rob't Crumb vignette that came to mind -


http://www.youtube.com/watch?v=3D3ym5n-ZZWUs&feature=3Drelated



Generally, the Agricultural value of Northern Hemisphere Soils have been
s-l-o-w-l-y going
downhill since the end of the last Ice Age...and, the manner of commercial
Farming,
especially in the last several generations, as you regard, has vastly
accelerated the decline.

Many vicious circles with this - the Vitality-Vigor of Plants, their
nutritional
value, and accommodation to both having been effected adversely by
increasingly
depleted and badly augmented Soils and other unhappy practices...on and
on...


Anyway...



Love,


Phil
