TAILIEUCHUNG - Livestock and Climate Change What if the key actors in climate change are…cows, pigs, and chickens?

Pyrethroid insecticide resistance in house flies is well documented in the United States. However, the extent to which it occurs in North Carolina poultry production has not been quantified. Pyrethroid resistance among other structural/environmental pests is not believed to be substantial at present, but recent investigations in other poultry producing states indicate the lesser mealworm, Alphitobius diaperinus, has significant levels of resistance to cyfluthrin and tetrachlorvinphos. Because this compound has been a mainstay of lesser mealworm control in North Carolina, it is likely that a similar resistance profile exists here. New, restrictive labeling for carbaryl has effectively removed. | Livestock and Climate Change Philip MacKenzie Duncan Rawlinson Lyle Rosbotham What if the key actors in climate change are. cows pigs and chickens 10 World Watch November December 2009 by Robert Goodland and Jeff Anhang Whenever the causes of climate change are discussed fossil fuels top the list. Oil natural gas and especially coal are indeed major sources of human-caused emissions of carbon dioxide CO2 and other greenhouse gases GHGs . But we believe that the life cycle and supply chain of domesticated animals raised for food have been vastly underestimated as a source of GHGs and in fact account for at least half of all human-caused GHGs. If this argument is right it implies that replacing livestock products with better alternatives would be the best strategy for reversing climate change. In fact this approach would have far more rapid effects on GHG emissions and their atmospheric concentrations and thus on the rate the climate is warming than actions to replace fossil fuels with renewable energy. Livestock are already well-known to contribute to GHG emissions. Livestock s Long Shadow the widely-cited 2006 report by the United Nations Food and Agriculture Organization FAO estimates that 7 516 million metric tons per year of CO2 equivalents CO2e or 18 percent of annual worldwide GHG emissions are attributable to cattle buffalo sheep goats camels horses pigs and poultry. That amount would easily qualify livestock for a hard look indeed in the search for ways to address climate change. But our analysis shows that livestock and their byproducts actually account for at least 32 564 million tons of CO2e per year or 51 percent of annual worldwide GHG emissions. This is a strong claim that requires strong evidence so we will thoroughly review the direct and indirect sources of GHG emissions from livestock. Some of these are obvious but underestimated some are simply overlooked and some are emissions sources that are already counted but have been .
