today there are 6.5 billion people by mid next century 9 billion.

Demand for energy to grow by 50% by 2030. US pop to grow by 34 % between 2005- 2030.

Chinese could have 800million cars if bought at the rate that Americans do. in 1990, 35 urban areas with over 5 million people. Today there are 54. 38 in the developing world. (plot) World largest City link .

The Center for Environment and Population each American in effect takes up 20 percent more land than he or she did 20 years ago.
Fifty-three percent of Americans live within 50 miles of a coast, on only 17 percent of the nation's land.
