Which causes more greenhouse gas emissions, raising cattle or driving cars?
Surprise - it's the cows. Yes, it's true that our cow-centric American diet contributes significantly to global warming. And cutting even some meat from our daily diets could have a greater effect than buying that eco-friendly car you've been oogling.
According to a recent report published by the United Nations Food and Agriculture Organization, the livestock sector generates more greenhouse gas emissions as measured in CO2 equivalent – 18 percent – than transport. It is also a major source of land and water degradation.
Meat production not only consumes a huge swath of agricultural land, but the by-product of animal raising - nitrous oxide and methane gases -- are no laughing matter as they contribute much more to the greenhouse effect than CO2.
This conclusion was supported by impressive data in a United Nations Food and Agriculture Organization (FAO) report issued last year: Livestock’s Long Shadow.
