Today we are an oil-based civilization, one that is totally dependent on a resource whose production will soon be falling. Since 1981, the quantity of oil extracted has exceeded new discoveries by an ever-widening margin. In 2008, the world pumped 31 billion barrels of oil but discovered fewer than 9 billion barrels of new oil. World reserves of conventional oil are in a free fall, dropping every year.
As I note in my latest book, Plan B 3.0: Mobilizing to Save Civilization, discoveries of conventional oil total roughly 2 trillion barrels, of which 1 trillion have been extracted so far, with another trillion barrels to go. By themselves, however, these numbers miss a central point. As security analyst Michael Klare notes, the first trillion barrels was easy oil, “oil that’s found on shore or near to shore; oil close to the surface and concentrated in large reservoirs; oil produced in friendly, safe, and welcoming places.” The other half, Klare notes, is tough oil, “oil that’s buried far offshore or deep underground; oil scattered in small, hard-to-find reservoirs; oil that must be obtained from unfriendly, politically dangerous, or hazardous places.”
This prospect of peaking oil production has direct consequences for world food security, as modern agriculture depends heavily on the use of fossil fuels. Most tractors use gasoline or diesel fuel. Irrigation pumps use diesel fuel, natural gas, or coal-fired electricity. Fertilizer production is also energy-intensive. Natural gas is used to synthesize the basic ammonia building block in nitrogen fertilizers. The mining, manufacture, and international transport of phosphates and potash all depend on oil.

Aside from the overriding need to stabilize atmospheric carbon dioxide (CO2) levels to stabilize climate, there are several other compelling reasons for countries everywhere to restructure their transport systems, including the need to prepare for falling oil production, to alleviate traffic congestion, and to reduce air pollution. The U.S. car-centered transportation model, with three cars for every four people, that much of the world aspires to will not likely be viable over the long term even for the United States, much less for everywhere else.
The shape of future transportation systems centers around the changing role of the automobile. This in turn is being influenced by the transition from a predominantly rural global society to a largely urban one. By 2020 close to 55 percent of us will be living in cities, where the role of cars is diminishing. In Europe, where this process is well along, car sales in almost every country have peaked and are falling.
With world oil output close to peaking, there will not be enough economically recoverable oil to support a world fleet expansion along U.S. lines or, indeed, to sustain the U.S. fleet. Oil shocks are now a major security risk. The United States, where 88 percent of the 133 million working people travels to work by car, is dangerously vulnerable.
