...Two environmental specialists for the World Bank, Robert Goodland (the bank’s former lead environmental adviser) and Jeff Anhang, claimed, in an article in World Watch, that the number was more like 51 percent. It’s been suggested that that number is extreme, but the men stand by it, as Mr. Goodland wrote to me this week: “All that greenhouse gas isn’t emitted directly by animals. ”But according to the most widely-used rules of counting greenhouse gases, indirect emissions should be counted when they are large and when something can be done to mitigate or reduce them.” ... If you believe that earth’s natural resources are limitless, which maybe was excusable 100 years ago but is the height of ignorance now, or that “technology will fix it” or that we can simply go mine them in outer space with Newt Gingrich, I guess none of this worries you. But if you believe in reality, and you’d like that to be a place that your kids get to enjoy, this is a big deal. A primer: The earth may very well be running out of clean water, and by some estimates it takes 100 times more water (up to 2,500 gallons) to produce a pound of grain-fed beef than it does to produce a pound of wheat. We’re also running out of land: somewhere around 45 percent of the world’s land is either directly or indirectly involved in livestock production, and as forests are cleared to create new land for grazing animals or growing feed crops, the earth’s capacity to sequester greenhouse gases (trees are especially good at this) diminishes. I could go on and on about the dangers of producing and consuming too much meat: heavy reliance on fossil fuels and phosphorous (both in short supply); consumption of staggering amounts of antibiotics, a threat to public health; and the link (though not as strong as sugar’s) to many of the lifestyle diseases that are wreaking havoc on our health. Here’s the thing: It’s seldom that such enormous problems have such simple solutions, but this is one that does. We can tackle climate change without inventing new cars or spending billions on mass transit or trillions on new forms of energy, though all of that is not only desirable but essential. In the meantime, we can begin eating less meat tomorrow. That’s something any of us can do, with no technological advances. If personal choice enacted on a large scale could literally save the world, maybe we have to talk about it that way. We could be heroes, like Bruce Willis in “Armageddon,” only maybe the sacrifice is on a more modest and easier scale. (You already changed your light bulbs; how about eating a salad?)
