Case in point:

Very high production agriculture requires a lot of fossil fuels, but to suggest that the Green Revolution was about converting fossil fuels into food is just misguided and misinformed.

If you're going to slam the NYT and its contributors that hard, please bring a little professionalism to the table.

The food sector, including input manufacturing, production, processing, transportation, marketing and consumption, accounts for approximately 30 per cent of global energy consumption, and produces over 20 per cent of global greenhouse gas emissions.

In the United States, 400 gallons of oil equivalents are expended annually to feed each American (as of data provided in 1994).7 Agricultural energy consumption is broken down as follows:

· 31% for the manufacture of inorganic fertilizer

· 19% for the operation of field machinery

· 16% for transportation

· 13% for irrigation

· 08% for raising livestock (not including livestock feed)

· 05% for crop drying

· 05% for pesticide production

· 08% miscellaneous8

Energy costs for packaging, refrigeration, transportation to retail outlets, and household cooking are not considered in these figures.

To give the reader an idea of the energy intensiveness of modern agriculture, production of one kilogram of nitrogen for fertilizer requires the energy equivalent of from 1.4 to 1.8 liters of diesel fuel. This is not considering the natural gas feedstock.9 According to The Fertilizer Institute (http://www.tfi.org), in the year from June 30 2001 until June 30 2002 the United States used 12,009,300 short tons of nitrogen fertilizer.10 Using the low figure of 1.4 liters diesel equivalent per kilogram of nitrogen, this equates to the energy content of 15.3 billion liters of diesel fuel, or 96.2 million barrels.

Of course, this is only a rough comparison to aid comprehension of the energy requirements for modern agriculture.

In a very real sense, we are literally eating fossil fuels. However, due to the laws of thermodynamics, there is not a direct correspondence between energy inflow and outflow in agriculture. Along the way, there is a marked energy loss. Between 1945 and 1994, energy input to agriculture increased 4-fold while crop yields only increased 3-fold.11 Since then, energy input has continued to increase without a corresponding increase in crop yield. We have reached the point of marginal returns. Yet, due to soil degradation, increased demands of pest management and increasing energy costs for irrigation (all of which is examined below), modern agriculture must continue increasing its energy expenditures simply to maintain current crop yields. The Green Revolution is becoming bankrupt.

Unfortunately, that has almost nothing to do with my comment.

have become completely useless as journals. They are very useful tools for propaganda to support the status quo.
