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.

Elevated global temperatures bring a number of threats, including rising seas and more crop-withering heat waves. Higher surface water temperatures in the tropical oceans also provide more energy to drive tropical storm systems, leading to more-destructive hurricanes and typhoons. The combination of rising seas, more powerful storms, and stronger storm surges can be devastating.
As noted in my most recent book, Plan B 3.0: Mobilizing to Save Civilization, just how devastating this combination can be became evident in late August 2005, when Hurricane Katrina came onshore on the U.S. Gulf Coast near New Orleans. In some Gulf Coast towns, Katrina’s powerful 28-foot-high storm surge did not leave a single structure standing. New Orleans survived the initial hit but was flooded when the inland levees were breached and water covered everything in large parts of the city except for the rooftops, where thousands of people were stranded. Even in August 2006, a year after the storm had passed, the most damaged areas of the city remained without water, power, sewage disposal, garbage collection, or telecommunications.
With advance warning of the storm and official urging to evacuate coastal areas, 1 million or so evacuees fled northward into Louisiana or to neighboring states of Texas and Arkansas. Of this total, more than 200,000 have not yet returned home and will likely never do so. These storm evacuees are the world’s first large wave of climate refugees.
Katrina was the most financially destructive hurricane ever to make landfall anywhere. It was one of eight hurricanes that hit the southeastern United States in 2004 and 2005. As a result of the unprecedented damage, insurance premiums have doubled, tripled, and even in some especially vulnerable situations gone up 10-fold. This enormous jump in insurance costs is lowering coastal real estate values and driving people and businesses out of highly exposed states like Florida.
As the earth warms, the melting of the earth’s two massive ice sheets—Antarctica and Greenland—could raise sea level enormously. If the Greenland ice sheet were to melt, it would raise sea level 7 meters (23 feet). Melting of the West Antarctic Ice Sheet would raise sea level 5 meters (16 feet). But even just partial melting of these ice sheets will have a dramatic effect on sea level rise.

In 1543, Polish astronomer Nicolaus Copernicus published “On the Revolutions of the Celestial Spheres,” in which he challenged the view that the sun revolved around the earth, arguing instead that the earth revolved around the sun. With his new model of the solar system, he began a wide-ranging debate among scientists, theologians, and others. His alternative to the earlier Ptolemaic model, which had the earth at the center of the universe, led to a revolution in thinking, to a new worldview.
Today we need a similar shift in our worldview, in how we think about the relationship between the earth and the economy. The issue now is not which celestial sphere revolves around the other but whether the environment is part of the economy or the economy is part of the environment. Economists see the environment as a subset of the economy. Ecologists, on the other hand, see the economy as a subset of the environment.
Like Ptolemy’s view of the solar system, the economists’ view is confusing efforts to understand our modern world. It has created an economy that is out of sync with the ecosystem on which it depends.

In the May issue of Scientific American Lester R. Brown, President of Earth Policy Institute, discusses how food shortages could be the weak link that brings down civilization.
In this feature article, “Could Food Shortages Bring Down Civilization?” Brown notes that the biggest threat to global political stability is the potential for food crises in poor countries to cause government collapse. Those crises are brought on by rising demand and ever worsening environmental degradation.
“In the twentieth century,” Brown says, “dramatic rises in grain prices results from poor harvests. They were event-driven and short-lived. In contrast, the recent escalation in world grain prices is trend-driven, making it unlikely to reverse the rise in food prices without a reversal in the trends themselves.”

Protecting the earth’s nearly 4 billion hectares of remaining forests and replanting those already lost are both essential for restoring the earth’s health, an important foundation for the new economy. Reducing rainfall runoff and the associated flooding and soil erosion, recycling rainfall inland, and restoring aquifer recharge depend on simultaneously reducing pressure on forests and on reforestation.
There is a vast unrealized potential in all countries to lessen the demands that are shrinking the earth’s forest cover. In industrial nations the greatest opportunity lies in reducing the quantity of wood used to make paper, and in developing countries it depends on reducing fuelwood use.
The rates of paper recycling in the top 10 paper-producing countries range widely, from China and Finland on the low end, recycling 33 and 38 percent of the paper they use, to South Korea and Germany on the high end, at 77 and 66 percent. The United States, the world’s largest paper consumer, is far behind South Korea, but it has raised the share of paper recycled from roughly one fourth in the early 1980s to 50 percent in 2005. If every country recycled as much of its paper as South Korea does, the amount of wood pulp used to produce paper worldwide would drop by one third.
The use of paper, perhaps more than any other single product, reflects the throwaway mentality that evolved during the last century. There is an enormous possibility for reducing paper use simply by replacing facial tissues, paper napkins, disposable diapers, and paper shopping bags with reusable cloth alternatives.

In early December 2004, Philippine President Gloria Macapagal Arroyo “ordered the military and police to crack down on illegal logging, after flash floods and landslides, triggered by rampant deforestation, killed nearly 340 people,” according to news reports. Fifteen years earlier, in 1989, the government of Thailand announced a nationwide ban on tree cutting following severe flooding and the heavy loss of life in landslides. And in August 1998, following several weeks of record flooding in the Yangtze River basin and a staggering $30 billion worth of damage, the Chinese government banned all tree cutting in the upper reaches of the basin. Each of these governments had belatedly learned a costly lesson, namely that services provided by forests, such as flood control, may be far more valuable to society than the lumber in those forests.
At the beginning of the twentieth century, the earth’s forested area was estimated at 5 billion hectares. Since then it has shrunk to just under 4 billion hectares, with the remaining forests rather evenly divided between tropical and subtropical forests in developing countries and temperate/boreal forests in industrial countries. Since 1990, the developing world has lost some 13 million hectares of forest a year. This loss of about 3 percent each decade is an area roughly the size of Greece. Meanwhile, the industrial world is actually gaining an estimated 5.6 million hectares of forestland each year, principally from abandoned cropland returning to forests on its own and from the spread of commercial forestry plantations. Thus, net forest loss worldwide exceeds 7 million hectares per year.
Unfortunately, even these official data from the U.N. Food and Agriculture Organization (FAO) do not reflect the gravity of the situation. For example, tropical forests that are clearcut or burned off rarely recover. They simply become wasteland or at best scrub forest, yet they still may be counted as “forest” in official forestry numbers. Plantations, too, count as forest area, yet they also are a far cry from the old-growth forest they sometimes replace.

Community opposition, legal challenges, and financial uncertainty over future carbon costs are prompting companies to rethink their plans for coal.
Since the beginning of 2007, 95 proposed coal-fired power plants have been canceled or postponed in the United States—59 in 2007, 24 in 2008, and at least 12 in the first three months of 2009. This covers nearly half of the 200 or so U.S. coal-fired power plants that have been proposed for construction since 2000. The vast majority of the remaining proposals are essentially on hold, awaiting word on whether the Environmental Protection Agency (EPA) is going to impose limits on carbon dioxide (CO2) emissions. With further legal challenges ahead and the regulation of CO2 imminent, 2009 may very well witness the end of new coal-fired power plants in the United States.
An April 2007 Supreme Court ruling is proving to be a seminal decision. In Massachusetts v. EPA, the Court ruled that the Clean Air Act gives the agency authority to regulate CO2 emissions and that the EPA must review whether such emissions pose a threat to public health or welfare. Complying with the Court order, new EPA Administrator Lisa Jackson submitted an endangerment finding to the White House in late March 2009 indicating that human health and welfare are indeed threatened by CO2 emissions. This finding opens the door to regulating CO2 emissions under the Clean Air Act. Such regulation would provide a backup option for curbing emissions if Congress fails to set limits on them through legislation.

Earth Policy Institute (EPI) has created a PowerPoint presentation that summarizes Lester Brown’s latest book, Plan B 3.0: Mobilizing to Save Civilization. It quickly reviews the book’s key concepts using data, facts, and figures, including the Plan B blueprint for reducing net carbon dioxide (CO2) emissions 80 percent by 2020 to stabilize climate.
All are welcome to use this presentation and modify it to suit their needs. It is designed to be shared, so feel free to pass along the link to others who might be interested. We ask only that users appropriately credit EPI and the photographers, notably Yann Arthus-Bertrand, eminent French photographer and friend of EPI, whose works appear within.

Ensuring basic health care for people in low-income countries is critical to the Plan B goal of eradicating poverty and stabilizing population.
While heart disease and cancer (largely the diseases of aging), obesity, and smoking dominate health concerns in industrial countries, in developing countries infectious diseases are the overriding health concern. Besides AIDS, the principal diseases of concern are diarrhea, respiratory illnesses, tuberculosis, malaria, and measles. Child mortality is high.
Progress in reaching the United Nations (U.N.) Millennium Development Goal of reducing child mortality two thirds by 2015 is lagging badly. As of 2005 only 32 of 147 developing countries are on track to reach this goal. In 23 countries child mortality has either remained unchanged or risen. And only 2 of the World Bank’s 35 fragile states are on track to meet this goal by 2015.
