Why is someone like George Monbiot so alarmist when you would think he would
Cropland- About 349 million acres in the U.S. are planted for crops. This is
the equivalent of about four states the size of Montana. Four crops --
feeder corn (80 million acres), soybeans (75 million acres), alfalfa hay (61
million acres) and wheat (62 million acres) -- make up 80 percent of total
crop acreage. All but wheat are primarily used to feed livestock.
The amount of land used to produce all vegetables in the U.S. is less
than 3 million acres.
So, the USA has essentially no need to produce corn or soybeans, because it
has no real need to eat that much meat (in fact, the USA would be far
healthier if it ate less corn-fed and soy-bean fed meat).
So, I don't worry much about a corn farmer not able to farm. Most of US
agriculture is unnecessary, as that article shows. So, let's say, with a
little belt tightening and vegetarism, we need to only farm about one third
the land we do in the USA, and everyone would be much healthier, also
reducing medical expenses annually by hundreds of billions of US dollars.
Equitably distributing the savings would be a matter of politics and a basic
Now, how to farm that 30% we still want to farm?
Well, while he mentions electric tractors at the end, George Monbiot could
have Googled "battery powered farm tractor" as I did (after a couple other
tries not so good, admittedly):
The top match:
Electric farm tractors are a much better idea than trying to run them on
biofuels because biofuels require about ten acres of a biofuels crop to
produce enough diesel fuel to run a typical farm tractor, such as those
below, for a year.
The owners of the two tractors below have gone a step further and have
solar-powered them. That means their tractors will run for years with
absolutely no fuel expense of any kind, and produce zero pollution. In
addition, these farmer won’t have to be immersed in the very noisy and
poisonous area of a typical diesel-powered tractor where they would be
forced to breathe diesel fumes all day long.
Tractors are obviously a great labor-saving device for farms, and more
people could invest in tractors such as these now for the current and future
labor-saving, health and environmental benefits.
EVMaine.org salutes these two pioneers for their visionary outlook, and
for their unique solutions.
I get the feeling it took very little time to do those conversions, looking
at the pictures.
Electric tractors used to be much bigger decades ago. There is one remaining
commercial producer according to that article, but just lawn tractor sized
But, here is a deeper issue. Lots of people like to work outdoors around
plants and animals. Maybe not everyone, but certainly more than the 1% to 2%
doing that now in the USA -- probably more like 10% to 30%, I'd guess,
considering gardening is the most popular outdoor recreational activity,
with more than 50% of households. Organic methods of agriculture might
require twice the labor, but would yield more with less fossil fuel inputs.
Remember, ground rock makes a good organic fertilizer; it is all you need if
you have some patience.
Also, good agricultural processes that focus on healthy soil avoid soil
compaction like tractors do. So, it might be better to do farming without
tractors. In the 1970s, various alternative designs were made for smaller
items, including things that could be put at the end of rows and which would
winch a line connected to an implement. In general, most farms are
electrified in the USA, and all sorts of electrical implements, either
battery powered or corded could be made to do farm tasks. And probably very
As I see it, the "tractor" represents an entire system of profit-maximizing
exploitive centrally controlled agriculture, where one farmer owns hundreds
of acres and takes all the profits themselves. Other systems, where people
have smaller plots, might be more enjoyable for many of the smaller scale
farmers who could use different types of equipment (including more robots).
As an example, here are three battery powered commercial robotic lawn mowers
-- which are essentially doing an agricultural task autonomously:
They work by doing mowing every day, so they do not need to be so powerful
or massive or noisy, and the grass is (they claim) healthier. This is an
example of rethinking the agricultural problem. You can replace big heavy
tractors with lots of smaller machines. If you develop good cord reeling and
unreeling systems, they don't even need batteries. (Maybe a good business
Here is a mowing robot that is radio controlled and uses liquid fuels, but
it is claimed it can replace five to twenty people with hand held equipment:
It's not a tractor, it's not a hand tool, but it is something in-between,
and probably much more fuel efficient than either.
So, there are all sorts of possibilities.
So, the only thing depleting faster than oil is the credibility of the Peak
Oil scaremongers who can't bother to do Google searches or think that deeply
about the issue. :-)
But with that said, are people lying about supply levels? I don't know. But
if they want to make the most money, maybe they want to start a panic to
drive up prices? It really is hard to know what "facts" to believe when
there is so much profit to be made by deception and misdirection.
