The Sustainable Agriculture Program is co-sponsoring a screening of “World Without Cows” on Nov. 17 at 5:30 p.m. in the Memorial Union Sun Room. The filmmakers traveled to more than 40 global locations to examine the cultural and economic significance of cows, their role in nourishing the world and their impact on climate. A post-screening panel will include Rodrigo Tarte, animal science and director of Certificate Studies in Meat Science.
