The signs are everywhere around us:
Sea level has risen 10–20 cm since 1900. Most non-polar glaciers are retreating, and the extent and thickness of Arctic sea ice is decreasing in summer.
In 1998 more than 45 percent of the globe’s people had to live on incomes averaging $2 a day or less. Meanwhile, the richest one- fifth of the world’s population has 85 percent of the global GNP. And the gap between rich and poor is widening.
In 2002, the Food and Agriculture Organization of the UN estimated that 75 percent of the world’s oceanic fisheries were fished at or beyond capacity. The North Atlantic cod fishery, fished sustainably for hundreds of years, has collapsed, and the species may have been pushed to biological extinction.
The first global assessment of soil loss, based on studies of hundreds of experts, found that 38 percent, or nearly 1.4 billion acres, of currently used agricultural land has been degraded.
Fifty-four nations experienced declines in per capita GDP for more than a decade during the period 1990–2001.
