At the bottom of a Washington Post article today on how cutting down your red meat intake dramatically improves your life expectancy, they mention the environmental impact:
In addition to the health benefits, a major reduction in the eating of red meat would probably have a host of other benefits to society, Popkin said: reducing water shortages and pollution, cutting energy consumption, and tamping down greenhouse gas emissions -- all of which are associated with large-scale livestock production.
"There's a big interplay between the global increase in animal food intake and the effects on climate change," he said. "If we cut by a few ounces a day our red-meat intake, we would have big impact on emissions and environmental degradation."
