Today there are three sources of growing demand for food: population growth; rising affluence and the associated jump in meat, milk, and egg consumption; and the use of grain to produce fuel for cars.
Population growth is as old as agriculture itself. But the world is now adding close to 80 million people per year. Even worse, the overwhelming majority of these people are being added in countries where cropland is scarce, soils are eroding, and irrigation wells are going dry.
Even as we are multiplying in number, some 3 billion of us are trying to move up the food chain, consuming more grain-intensive livestock products. As incomes rise, annual grain consumption per person climbs from less than 400 pounds, as in India today, to roughly 1,600 pounds, as among those living high on the food chain in the United States, where diets tend to be heavy with meat and dairy products.

The scientific community has long agreed that our dependence on fossil fuels inflicts massive damage on the environment and our health, while warming the globe in the process. But beyond the damage these fuels cause to us now, what will happen when the world’s supply of oil runs out?
Peak Oil is the point at which petroleum production reaches its greatest rate just before going into perpetual decline. In “Peak Oil and a Changing Climate,” a new video series from The Nation and On The Earth productions, radio host Thom Hartmann explains that the world will reach peak oil within the next year if it hasn’t already. As a nation, the United States reached peak oil in 1974, after which it became a net oil importer.
Bill McKibben, Noam Chomsky, Nicole Foss, Richard Heinberg and the other scientists, researchers and writers interviewed throughout “Peak Oil and a Changing Climate” describe the diminishing returns our world can expect as it deals with the consequences of peak oil even as it continues to pretend it doesn’t exist. These experts predict substantially increased transportation costs, decreased industrial production, unemployment, hunger and social chaos as the supplies of the fuels on which we rely dwindle and eventually disappear.
