In this weekly series we have been discussing the benefits of a vegetarian diet including: food safety , animal rights, better health, global food crisis, frugal living and the immense contribution of meat production to climate change/depletion of resources
Writing in the journal Environmental Science & Technology, Xiaobo Xue and Amy Landis examine which foods contribute most to ocean dead zones through nitrogen pollution and compared this with their carbon footprint, as established by previous studies. Red meat topped both footprint lists, making it the food with the greatest impact on both climate change and eutrophication: Eating a pound of beef creates about 22 lb of greenhouse gases and about 2.5 oz of nitrogen pollution. Cereals and carbohydrates had the smallest footprints, with each pound of food releasing only 3 lb of greenhouse gases and almost no nitrogen pollution.
