News of the 300 millionth American has been accompanied by the usual environmentalist alarms about degradation of the environment and depletion of natural resources.

To give just two examples, since 1975, the number of times that Los Angeles air exceeded ozone standards dropped from 192 to 27, despite stricter standards. Although the number of cars and trucks in the U.S. has doubled since 1970, and the number of miles driven has increased by 181 percent, emissions of volatile organic compounds has decreased by 73.8 percent (see 11th Annual Index of Leading Environmental Indicators 2006 by Steven Hayward www.pacificresearch.org).
