The Journal of Animal Science has published new research looking at the consequences if U.S. farmers and ranchers no longer used productivity-enhancing technologies to raise beef cattle. The peer-reviewed article, "The environmental and economic impact of removing productivity-enhancing technologies from U.S. beef production," was co-authored by Jude Capper, Ph.D., of Washington State University, and Dermot Hayes, Ph.D., of Iowa State University, and appears in the journal's October issue.
This research, which also was presented at the 2012 American Society of Animal Science annual meeting, found that discontinuing use of scientifically proven, U.S. Food and Drug Administration-approved technologies would create sobering unintended consequences. To produce the same amount of U.S. beef annually without using these technologies, U.S. farmers and ranchers would need 10 million more beef cattle, 81 million more tons of feed, 17 million more acres of land, and 138 billion more gallons of water. In addition, 18 million extra metric tons of carbon dioxide equivalent (CO2eq) would be released in the United States alone.
"These effects are equivalent to imposing an 8.2 percent tax on U.S. beef farmers and ranchers, leading to a 17 percent reduction in U.S beef production by 2023," says Capper. "In turn, other countries would increase beef exports. Environmentally, this would mean the release of 3.1 billion more metric tons of CO2eq, and the destruction of 16.9 million acres of Amazon rain forest and forests in the west central Cerrado regions of Brazil.
"The bottom line is that losing the ability to use safe, approved technologies will create significant environmental and economic challenges that are undesirable and unnecessary," Capper concludes.
