Do cows cause global warming?

Environmental Protection Agency (EPA) reports indicate that cattle production is not a top contributor to greenhouse gasses. The agriculture industry accounts for 9% of total U.S. greenhouse gas emissions. For comparison, transportation accounts for 28%, and electricity generation accounts for 28% of total U.S. greenhouse gas emissions. Advances in the industry helped American farmers and ranchers reduce their carbon footprint. Methane emissions from U.S. beef cattle have declined 34% since 1975.
