Air Issues Associated with Animal Agriculture: A North American Perspective

Resumen

The purpose of this CAST Issue Paper (IP 47) is to go beyond the generalizations and accusations often associated with the air quality topic. Experts from six universities examine a large amount of data and focus their information and conclusions around the key livestock areas: swine, poultry, dairy, and beef. Their critical analyses look at a wide scope of issues, from greenhouse gas emissions to the logistics of manure storage facilities. The U.S. Environmental Protection Agency is increasing efforts to monitor emissions from agriculture, so further research is important for all parties involved, and this paper provides solid, science-based information.
