LETTERS I agree with the IPAT formula, only I found it ironic to see bicycles illustrated in the PAT box graphic. Flying machines, weapons, computers, and ships definitely belong. The bicycle, fi however, is arguably the best mode of transportation man- kind has. It is in a position to lessen human impact, if only it would be used by more of the world's population. This includes factors such as environment, health benefits, and effi fi ciency fi of transport. WILLIAM STELTER Tahoe City, California While technological growth can help us consume more and introduce more new pol- lutants, it can also ameliorate the effects of increasing popu- lation and consumption. The development of substitutes for chlorofluorocarbons allowed us fl to maintain high levels of growth while reducing our impact on ozone depletion. With our popu- lation approaching seven billion, technology may be our only option for sustainability. KEMI GEORGE Williamsburg, Virginia Our impact on our environment will not be mitigated until we devise an economy that does not depend on constant increases in consumption and production. This is a tall order, but even total population stability will not work without it. AL ROGERS Duryea, Pennsylvania I don't like the coined term "anthropocene" in your article. Since all of the large number of fertile people today were born from fertile women, I think the word "archocene" (from the Greek archos, meaning "master") is far more appropriate. The other is far too male---too androcentric! Gender-specific terms that are fi all-inclusive are antiquated.
