To remake our outmoded notions of economics--and to save the global environment--the Worldwatch Institute delivers a comprehensive, persuasive guide to achieving a sustainable economy based on energy efficiency and reuse, rather than waste, of resources. Using an analogy to the denial that ran rampant on the Titanic, the authors of the Institute's yearly State of the World series stress the urgent need to move away from a fossil-fuel economy in order to counteract global warming. ``Renewables'' are the key: Brown and his colleagues present tables demonstrating that wind and solar energy will create more jobs than coal and oil development will, and argue that the hazards of nuclear waste and accident obviate the viability of nuclear power. ``When it comes to solar technologies, today's political leaders, still captivated by coal and nuclear power, are akin to the steam engine's 18th-century skeptics.'' The farming of rain forests' natural products (nuts, medicines, rubber) could be substituted for clear-cutting; farming methods that prevent erosion, such as ``intercropping,'' could help feed a stable population (the authors argue that the earth, currently home to 5.4 billion people, cannot sustain more than 8 billion without catastrophic famine and disease). ``Sustainable progress'' rather than standard economic growth would take into account equity for women, the poor, other species, and future generations. Indicators should be adjusted, the authors say, so that for every economic gain that enhances GNP, such as the cutting and selling of trees, a debit--the destruction of that resource- -should be factored in. The refreshing thing about Worldwatch, in addition to its sane, can-do rather than alarmist attitude, is its balanced international scope, its drawing of statistics and examples from every continent. This volume, which launches a Worldwatch Environmental Alert Series, should be made part of the economic and political-science curriculum for undergraduates and graduate programs, including business schools.
