The human population must be stabilized; that is, we must slow population growth. In many countries of sub-Saharan Africa, the Near East, and South Asia, human population continues growing at 2 percent a year or faster, and the average woman bears four to seven children. We should help people plan their families by funding family planning and information services.
Energy efficiency must be improved. We should work to develop new and renewable energy sources, encourage the design and use of low-energy buildings, eliminate government subsidies for fossil fuels, encourage energy efficiency programs in industry, invest in public transportation, and introduce "hypercars."
