Tofu For Planetary Survival

Remember when the Bush Adminstration boasted about how they reduced greenhouse gas emissions by 1% in 2006? Remember how this showed that they were on the right path to solving the climate crisis? Yeah, well, that's no longer operative.

According to a new release from the Energy Information Administration, “U.S. greenhouse gas emissions in 2007 were 1.4 percent above the 2006 total.” This increase erases the 1% drop in emissions in 2006, for which Bush claimed credit (even though the decrease was due to an unusually warm winter and high fuel prices).


So, if warm winters have the effect of decreasing greenhouse gas emissions, then maybe global warming is the only way to stop global warming! Ever think of that, Al Gore?

Still, this kind of puzzles me. Gas prices were high in 2006, but they hit a record high in 2007, and were consistently higher than the previous year. It doesn't make a lot of sense, outside of just general increases in demand, to see emissions rise. Unless, you know, this is all about the cows rather than the cars.

When Rajendra Pachauri, who runs the Intergovernmental Panel on Climate Change (IPCC), made a suggestion that could reduce global greenhouse gas emissions by as much as 18 percent, he was excoriated. Why was his proposal so unpalatable? Because he suggested eating less meat would be the easiest way people could reduce their carbon footprint, with one meat-free day per week as a first step [...] Boris Johnson, London's outspoken mayor, posted a long screed on his blog, declaring, "The whole proposition is so irritating that I am almost minded to eat more meat in response."

Johnson may not appreciate the environmental value of replacing his steak and kidney pie with a tofu scramble, but the benefits would be quite real. Animal agriculture is responsible for local pollution from animal waste and chemical use and for greenhouse gas emissions from the energy-intensive process of growing feed and raising livestock, plus the, ahem, byproducts of animal digestion. It would be much easier -- and cheaper -- to give up meat than to, say, convert an entire country's electrical grid to using solar, wind, or nuclear energy. A rural Montanan might have no choice but to drive to work, but he can certainly switch out his pork chop for pinto beans. While Pachauri was correct to note that one need not go vegan to help the environment -- simply eating less meat would help -- he could have also emphasized the more politically appealing point that one can be a carnivore and still reduce one's impact by choosing different meats. Even limiting one's meat consumption to chicken yields major environmental benefits -- not to mention health and financial benefits [...]

Now should be environmental vegetarianism's big moment. Global warming is the single biggest threat to the health of the planet, and meat consumption plays a bigger role in greenhouse gas emissions than even many environmentalists realize. The production and transportation of meat and dairy, particularly if you include the grains that are fed to livestock, is much more energy-intensive than it is for plants. Animals, especially cattle, also release gases like methane and nitrous oxide that, pound for pound, are up to 30 times more damaging than carbon dioxide. Internationally there is an additional cost to animal agriculture: massive deforestation to make land available for grazing, which releases greenhouse gases as the trees are burned and removes valuable foliage that absorbs carbon dioxide. As a result, according to a 2006 United Nations report, internationally the livestock sector accounts for 18 percent of all greenhouse gas emissions -- more than the transportation sector.


While typing this, I recognized that I had a meat-free day yesterday: grapefruit for breakfast, meatless chicken nuggets (quite tasty!) for lunch, and my world-famous bean and cheese quesadillas for dinner. Getting the whole country on board with this might be even harder than making every car a Prius, but it'd be good to see at least some emphasis on the role of food consumption in energy and carbon policy.

There are so many systems that rely on burning carbon that it's going to be extremely difficult to get them all in order without a comprehensive strategy. And that includes meat-eating.
