Tracking Beef’s Shrinking Footprint

A study published in this month’s Journal of Animal Science found that raising a pound of beef in the United States today uses significantly fewer natural resources, including land, water, feed and fuel than in the past. “The Environmental Impact of Beef Production in the United States: 1977 compared with 2007” (Journal of Animal Science, December 18, 2011) by Jude Capper, Ph.D., Washington State University, documents that each pound of beef raised in 2007 used 33 percent less land, 12 percent less water, 19 percent less feed and 9 percent less fossil fuel energy than equivalent beef production in 1977. Waste outputs were similarly reduced, shrinking the carbon footprint of beef by 16.3 percent in 30 years. According to Capper’s research, improvements in the way cattle are raised and fed in the United States between 1977 and 2007 yielded 13 percent more total beef from 30 percent fewer animals...more
