Socialism failed because it couldn't tell the economic truth. Capitalism may fail because it couldn't tell the ecological truth.

Yet, most of the readily accessible reserves of oil formed over hundreds of millions of years will be consumed within a single generation, spanning the years from 1960 to 1995.

In the Middle East, where populations are growing fast, the world is seeing the first collision between population growth and water supply at the regional level. For the first time in history, grain production is dropping in a geographic region with nothing in sight to arrest the decline. Each day now brings 10,000 more people to feed and less irrigation water with which to feed them.

Another agricultural trend of growing concern is the increased nutrient content of coastal waters resulting from fertilizer runoff in agricultural regions. Augmented by urban sewage discharge in some situations, this results in huge algal blooms, which, as they die and decay, deplete the oxygen content in the water, leading to the death of the fish.

Among the environmental trends undermining our future are shrinking forests, expanding deserts, falling water tables, collapsing fisheries, disappearing species, and rising temperatures. The temperature increases bring crop-withering heat waves, more-destructive storms, more-intense droughts, more forest fires, and, of course, ice melting. We are crossing natural thresholds that we cannot see and violating deadlines that we do not recognize.

The foundation is being laid for the emergence of both wind and solar cells as cornerstones of the new energy economy. World wind generating capacity grew from 7,600 megawatts in 1997 to 9,600 in 1998, an expansion of 26 percent. At a national level, Germany led the way, adding 790 megawatts of capacity, followed by Spain with 380 megawatts, and the United States with 226 megawatts. In the past, U.S. wind generating capacity was concentrated in California, but in 1998, wind farms began generating electricity in Minnesota, Oregon, and Wyoming, broadening the new industry's geographical base.
