The following is from CAST's press release and is important for livestock ranchers to read. Air quality is another issue that ranchers and livestock producers need to keep on top of and know the actual science.
CAST’s new Issue Paper goes beyond the generalizations and accusations often associated with the air quality topic. Chaired by Dr. Larry Jacobson from the University of Minnesota, experts from six universities 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.
CAST Issue Paper #47, Air Issues Associated with Animal Agriculture: A North American 
Perspective was released on Thursday, May 5. Dr. Frank Mitloehner (right), one of the co-authors, referred to the paper at the Animal Agriculture Alliance Summit meeting in Washington, D.C. Mitloehner directs the Agricultural Air Quality Center at the University of California-Davis, and his presentation at the summit will focus on "The Truth About Sustainability--Debunking 'Livestock’s Long Shadow'."

About CAST
CAST is a nonprofit 501 (c)(3) organization composed of scientific societies and many individual, student, company, nonprofit, and associate society members. CAST's Board is composed of representatives of the scientific societies, commercial companies, and nonprofit or trade organizations, and an executive committee. CAST was established in 1972 as a result of a 1970 meeting sponsored by the National Academy of Sciences, National Research Council.
The primary work of CAST is the publication of task force reports, commentary papers,
special publications, and issue papers written by scientists from many disciplines. The CAST Board is responsible for the policies and procedures followed in developing, processing, and disseminating the documents produced. These publications and their distribution are fundamental activities that accomplish CAST's mission to assemble, interpret, and communicate credible science-based information regionally, nationally, and internationally to legislators, regulators, policymakers, the media, the private sector, and the public. The wide distribution of CAST publications to nonscientists enhances the education and understanding of the general public.
CAST addresses issues of animal sciences, food sciences and agricultural technology, plant and soil sciences, and plant protection sciences with inputs from economists, social scientists, toxicologists or plant pathologists and entomologists, weed scientists, nematologists, and legal experts.
