Nine per cent of all green house gas emissions in the US are from Agriculture and cattle are responsible for 2%.  To identify the magnitude of the challenges, EPA does an annual inventory of the GHG contributions from each industry. In the effort to achieve carbon neutrality, Methane from cattle production has become a major target; however per capita consumption has already been declining for years while the population keeps growing, with corresponding demand for more meat in global diets.  Fortunately solutions are being found in programs like AgNext at Colorado State University where Dr. Sara Place is a Professor of Feedlot Systems. www.agnext.colostate.edu
