Dr. Sarah Klopatek is a sustainability and cattle systems scientist at UC Davis.  As a scientist, she explains why it is often difficult to reduce complex questions to a simple answer, leading to her statement, "myopia is the death of sustainability."  Her most recent publication explores the differences in nutritional profiles in beef from cattle raised in a variety of grain- and grass-fed systems.  In our fascinating conversation she explains these differences, as well as the environmental impact of the production systems.
