A Malodorous Fog

Published: August 7, 2005

Here is an axiom for farmers and consumers: Crowding animals together in large numbers always leads to problems. It turns hog manure, for instance, from a source of fertility into toxic waste. It creates enormous opportunities for disease, which tends to be warded off by inappropriate use of antibiotics. And in central California, it turns dairies, which are environmentally benign on a small scale, into major sources of air pollution - perhaps as bad as automobiles.

One of the smoggiest places in the country is the San Joaquin Valley, where one-fifth of the country's dairy cattle live - some 2.5 million animals and still growing. Local environmentalists and some local legislators argue that cow emissions - which come mostly from the front end of the animal rather than the tailpipe - have gotten out of control. There is a growing call to impose new rules that would improve air quality. The best way to do this isn't completely clear. But few, if any, of the proposed solutions would be palatable to the dairy farmers.

The San Joaquin Valley Air Pollution Control District estimates that at present each cow emits 19.3 pounds of pollutants a year in the form of gases from manure, from regurgitation and from flatulence. Defenders of the dairy farms - a large and powerful California industry - say that number is a wild overestimation. But behind the debate over the emissions measurements and their regulatory implications, there is a simple fact to contend with: the eye-stinging, nose-burning smell of cattle congestion in rural California.
