If you think you are spending more each week at the supermarket, you may be right. The escalating share of the U.S. grain harvest going to ethanol distilleries is driving up food prices worldwide. Corn prices have doubled over the last year, wheat futures are trading at their highest level in 10 years, and rice prices are rising too. In addition, soybean futures have risen by half.
Between the years 2008 and 2020, we are likely to see a still unimaginably sweeping shift away from fossil fuels and high-contamination modes of powering our economy. The transition will have a political component, but will be driven mostly by cost concerns, resource scarcity, and public demand for cleaner air and responsible climate policy, a demand which is not ideological in nature.
The global consumption of bottled water reached 154 billion liters (41 billion gallons) in 2004, up 57 percent from the 98 billion liters consumed five years earlier. Even in areas where tap water is safe to drink, demand for bottled water is increasing—producing unnecessary garbage and consuming vast quantities of energy. Although in the industrial world bottled water is often no healthier than tap water, it can cost up to 10,000 times more. At as much as $2.50 per liter ($10 per gallon), bottled water costs more than gasoline.
Peak oil is described as the point where oil production stops rising and begins its inevitable long-term decline. In the face of fast-growing demand, this means rising oil prices. But even if oil production growth simply slows or plateaus, the resulting tightening in supplies will still drive the price of oil upward, albeit less rapidly.
Few countries are planning a reduction in their use of oil. Even though peak oil may be imminent, most countries are counting on much higher oil consumption in the decades ahead, building automobile assembly plants, roads, highways, parking lots, and suburban housing developments as though cheap oil will last forever.
On March 16, 2003, some 10,000 participants [met] in Japan for the third World Water Forum to discuss the world water prospect. Although they [would] be officially focusing on water scarcity, they [would also] indirectly be focusing on food scarcity because 70 percent of the water we divert from rivers or pump from underground is used for irrigation.
As world water demand has tripled over the last half-century, it has exceeded the sustainable yield of aquifers in scores of countries, leading to falling water tables. In effect, governments are satisfying the growing demand for food by overpumping groundwater, a measure that virtually assures a drop in food production when the aquifer is depleted. Knowingly or not, governments are creating a “food bubble” economy.
Water is one of the “fundamental building-blocks of life”, as is often said in science, in biology classrooms, in medicine, theology, environmental policy debates, and in cosmology and space exploration. It is also a commodity whose economic reality is increasingly defined by chronic scarcity and often intensely uneven distribution.
The Hot Spring connects people to brainstorm, solve problems, and build a more just, more sustainable future.
