Introduction

HE GREEN REVOLUTION, which began in the 1960s, did not cure world hunger. But it did transform food production into an industry, and allow for the consolidation of small farms into what have become the large agribiz corporations. While the abundance of cheap food that resulted did nothing to alleviate world hunger, it did allow the human population to grow far in excess of the planet's carrying capacity. The Green Revolution achieved all of this by making food production extremely dependent on...

Land Degradation

I AND DEGRADATION_mostly due to soil erosion, mineral depletion, and urbanization_is becoming a major problem worldwide. Currently, the full scope of the problem is hidden because lost vitality is compensated for by intensified use and increased application of artificial fertilizers. In the end, these strategies only exacerbate the problem, leading to a total collapse of soil viability. Since 1945, the total land degraded by soil depletion, desertification, and the destruction of tropical...

Eating Fossil Fuels

OLAR ENERGY is a renewable resource limited only by the inflow rate from the sun to the earth. Fossil fuels, on the other hand, are a stock-type resource that can be exploited at a nearly limitless rate. However, on a human time scale fossil fuels are nonrenewable. They represent a planetary energy deposit that we can draw from at any rate we wish, but which will eventually be exhausted without hope of renewal. The Green Revolution tapped into this energy deposit and used it to increase...

The Green Revolution

At just the point when agriculture was running out of unex-ploited tillable lands, technological breakthroughs in the 1950s and 1960s allowed it to continue increasing production through the use of marginal and depleted lands. This transformation is known as the Green Revolution. The Green Revolution resulted in the industrialization of agriculture. Part of the advance resulted from new hybrid food plants, leading to more productive food crops. Between 1950 and 1984, as the Green Revolution...
