Much has been said about cattle that increase carbon and methane levels in the atmosphere. Test were done on cattle in the European Union. Options were considered on how the emissions could be reduced. It was found that dairy and beef cattle contributed 60 per cent of pollution for the whole livestock industry. Because little can be done about body waste emissions, efficiency factors were at the center of the study. Poor land use was the second highest factor in global greenhouse gas emissions after direct production. Pollution for wasted food followed inefficient use of land. As usual the investigators did their calculations on how much pollution could be lessened if their advice was adopted by the livestock industry. It was estimated that the lowest impact would be a reduction of 12 per cent. Optimists in the group said 60 per cent. Somehow consumption of meat was to be reduced. Just how this was to be done was not made clear. With people in developing countrie...
