Wake-up call for carnivores

My wife and I have been meatless for a long time now. It feels really good, and though we occasionally (once a month?) used to have fish/seafood, we are cutting that out entirely now. An eye-opening report in the NYT explains the global, environmental and economic impact of American's carnivorism.
Growing meat (it’s hard to use the word “raising” when applied to animals in factory farms) uses so many resources that it’s a challenge to enumerate them all. But consider: an estimated 30 percent of the earth’s ice-free land is directly or indirectly involved in livestock production, according to the United Nation’s Food and Agriculture Organization, which also estimates that livestock production generates nearly a fifth of the world’s greenhouse gases — more than transportation.

To put the energy-using demand of meat production into easy-to-understand terms, Gidon Eshel, a geophysicist at the Bard Center, and Pamela A. Martin, an assistant professor of geophysics at the University of Chicago, calculated that if Americans were to reduce meat consumption by just 20 percent it would be as if we all switched from a standard sedan — a Camry, say — to the ultra-efficient Prius. Similarly, a study last year by the National Institute of Livestock and Grassland Science in Japan estimated that 2.2 pounds of beef is responsible for the equivalent amount of carbon dioxide emitted by the average European car every 155 miles, and burns enough energy to light a 100-watt bulb for nearly 20 days.
Read it all.

Some people just don't understand the environmental impacts of the meat industry -- how much of our fresh water supplies are polluted and how much forest is burned simply to raise cattle. The toll is significant. It really can't be overstated. For those interested in sustainability and the relationship between oil and agriculture, the data is out there.
