[单项选择]Until recently, the planet was a large world in which human activities and their effects were neatly compartmentalized within nations, within sectors (energy, agriculture, trade), and within broad areas of concern ( environmental, economic, social). These compartments have begun to dissolve. This applies in particular to the various "global" rises that have seized public concern, particularly over the past decade. These are not separate crises: an environmental crisis, a development crisis, and energy crisis. They are all one. The planet is passing through a period of dramatic growth and fundamental change. Our human world of 5 billion must make room in a finite environment for another human world. The population could stabilize at between 8 billion and 14 billion in this century, according to U.N. predictions. More than 90 percent of the increase will occur in the poorest countries, and 90 percent of that growth in already bursting cities.
