Robert Zubrin calls for challenging OPEC looting!

Mind Blowing interview with Robert Zubrin on CoastToCoastAm with George Noorey….really worth buying a copy of the audio! Zubrin points out that the move of Oil prices from $10 to $120 per barrel of oil is 1200% ! , Dudes! This is a Bush/Cheney/Republican TAX HIKE! Duh! This is the third person in the media to mention that they thought that people were now trying to break up the USA. Like was done to Yugoslavia and the USSR.

Next, author Robert Zubrin warned that the OPEC cartel wants to crash the American economy and then "buy out the wreckage." He argued for a flex fuel mandate (so that cars will run on both gasoline and alcohol) and said that increased ethanol production is not related to food shortages. 500 million acres of US farmland are not being utilized, and we have tremendous capacity to expand production, he commented.

Intensive crop culture for high population is unsustainable by Peter Salonius

Intensive crop culture for high population is unsustainable Print
Written by Peter Salonius
Editor's note: The following essay by soil scientist Peter Salonius is Part One of his two-part series for Culture Change that bursts the delusion of agriculture's providing for a large human population long-term. If after reading it you have doubt, read the scientific basis for it: the second part in the series, "Unsustainable soil mining, past, present and future." (A version of the second part was published in the May/June,2007 issue of The Forestry Chronicle.) The author lives in New Brunswick, and he published in Culture Change in 2003 "Energy tax made easy: Modifying human excess with international non-renewable energy taxation" (see link at bottom). – JL

I am convinced that we begin unsustainable resource depletion (overshoot) as soon as we use (and become dependent upon) the first unit of any non-renewable resource or renewable resource used unsustainably whose further use becomes essential to the functioning of society, such as:

THE FIRST TONNE OF COAL
THE FIRST LITRE OF OIL
THE FIRST KILOGRAM OF FISSIONABLE URANIUM
THE FIRST BARREL OF FOSSIL WATER FOR IRRIGATION — and
THE FIRST HECTARE OF FORMERLY NUTRIENT CONSERVATIVE NATIVE FOREST or GRASSLAND/PRAIRIE PLOWED

This last category of unsustainable renewable resource depletion (excessive leaching/export of plant nutrients from arable soils associated with most agricultural practice, and more recently also with harvesting of nutrient-rich forest biomass) has been looming over us, unseen, for 10,000 years. We can expect that it will catch up with us shortly because most of us are dependent on foodstuffs produced by unsustainable farming, and fiber produced by unsustainable forestry.

Unsustainable soil mining: past, present and future Print
Written by Peter Salonius
[This is Part Two of Peter Salonius's two-part series. The first part, "Intensive crop culture for high population is unsustainable", can be viewed by using the link at bottom.] ABSTRACTHuman settlement has increased food production by progressively converting complex, self-managing natural ecosystems with tight nutrient cycles into simplified, intensively managed agricultural ecosystems that are subject to nutrient leaching. (Most agriculture is unsustainable in the long term.)

Conventional stem wood forest harvesting is now poised to be replaced by intensive harvesting of biomass to substitute for increasingly scarce non-renewable fossil fuels. Removal of nutrient-rich forest biomass (harvesting of slash) can not be sustained in the long term.

[Key Words: soil nutrient depletion, biomass harvesting, site productivity]

Introduction

A general discussion of the concept of sustainability was presented by Gatto (1995), who suggested that notions of sustainability "reflect different priorities and optimization criteria, which are notoriously subjective"; however, the goal of maintaining soil-productive capacity is not a subjective notion. In this paper I will show that long term sustainable terrestrial carrying capacity depends on the maintenance of self-managing, nutrient-conservative plant communities.

The dynamic cyclical stability of complex ecosystems has been shown, for most animal populations, to depend on the ability of predators to dampen overshoot and runaway consumption dynamics of prey species (Rooney et al, 2006).

Haber-Bosch process has often been called the most important invention of the 20th century

this ties in with the earlier post on Peak Phosphorus

from Juergen Schmidhuber's site

Since age 15 or so Prof. Jürgen Schmidhuber's main scientific ambition has been to build an optimal scientist, then retire. In 2028 they will force him to retire anyway. By then he shall be able to buy hardware providing more raw computing power than his brain

Their Haber-Bosch process has often been called the most important invention of the 20th century (e.g., V. Smil, Nature, July 29 1999, p 415) as it "detonated the population explosion," driving the world's population from 1.6 billion in 1900 to 6 billion in 2000.

Haber-Bosch process:

Under high temperatures and very high pressures, hydrogen and nitrogen (from thin air) are combined to produce ammonia.

Nearly one century after its invention, the process is still applied all over the world to produce 500 million tons of artificial fertilizer per year. 1% of the world's energy supply is used for it (Science 297(1654), Sep 2002); it still sustains roughly 40% of the population (M. D. Fryzuk, Nature 427, p 498, 5 Feb 2004).

sample from Jon Ott-

"The End of the Treasure in the Basement", by Jonathan Ott

Jonathan described himself as "not a prophet", but someone who has been interested in the question of energy and the petroleum-based political and economic infrastructure of the industrialized world since the 1970s. He's surprised that the infrastructure has held itself together as long as it has.

Most known organisms derive their energy from the sun, which was properly regarded by many religious cultures as the origin of life.

….

Since 1979 the amount of energy per capita has decreased, and more people have no access to energy and water every year. We're starting over the hill and soon it will be a cliff. This is important because energy equals life, in a literal and direct equation. What Hubbard pointed out was the disparity between the natural ecology of energy and the economic system of the world.

So we start looking to alternatives to oil, coal, natural gas, and wood. Take nuclear energy � it is highly efficient in generating electrical power, but it requires a huge investment of energy to operate. Nuclear power plants must have their own power plant to run, and it may be the case that nuclear power does not even generate net energy.

Fusion reactors are too little, too late. A best-case scenario is production of fusion power in 2050, and that's way too late.

There are currently four countries that have not yet reached their peak. Jonathan predicts that within 30 years the wheels will come off the global economy. Perhaps as soon as 20, but definitely by 30.

Jonathan's response to this situation has been to create a self-sufficient solar and water power supply that powers his lights, a short-range electric car, and his basic needs. He's beginning to generate all of his own food in a sustainable little farm as well, and his hope is to live to see the day when everything comes unglued so he can see what happens.

    Peak Phosphorus

    Posted by Prof. Goose on August 17, 2007 – 10:00am

    Tags: agriculture, depletion, hubbert linearization, phosphorus, recycling

    This is a guest post by Patrick Déry and Bart Anderson. Patrick Déry is a physicist, energy, agriculture and environment analyst and consultant in Quebec, Canada. Bart Anderson is a former reporter, teacher and technical writer; he currently is co-editor of Energy Bulletin. Peak oil has made us aware that many of the resources on which civilization depends are limited.
    But oil production is not the whole story. Nutrients like nitrogen and phosphorus were also required for the "Green Revolution".

    Nitrogen is present in large quantity in the atmosphere (78% of its composition). The Haber-Bosch process for obtaining nitrogen uses one percent of all energy consumed by humans [5]. Nitrogen can also be fixed in the soil using micro-organisms such as rhizobium and azotobacters. If there is sufficient energy, nitrogen will be available.

    Phosphorus may be the real bottleneck of agriculture. [6]

    Population growth was only possible because we found phosphorus deposits and cheap energy to extract, transform and transport it to farms. When we plot data of world population versus world phosphate production, we find a significant correlation.

    What does this correlation mean? Even if we find a real substitute for fossil fuels, it will be impossible to maintain population growth because phosphate deposits are probably in decline. It will be impossible to maintain an agriculture without recycling nutrients.
