One certainly cannot neglect emissions from the livestock sector but to compare them to the main emission sources would put us on a wrong path to solutions, namely to significantly reduce our anthropogenic carbon footprint to reduce climate change. The livestock sector supports about 1.3 billion producers and retailers, and contributes 4050% of agricultural GDP.

A large number of Climate experts predict that if we continue emitting greenhouse gases at the current rate, most of the summer in Illinois will consist of so-called dangerous heat days. remaining liquid fraction is still a potential source of indirect nitrous oxide emissions.
