Testimony at a recent Senate Agriculture Committee hearing on solutions to climate change focused on what farmers and ranchers are already doing to lighten their impact on the environment and improve sustainability. They also stressed that solutions must be economically feasible, and that these are difficult times for producers to invest in new conservation practices. But Tom Vilsack, president and CEO of the U.S. Dairy Export Council and former U.S. secretary of agriculture, took the conversation to another level, pointing out the opportunities that lie in sustainable practices.
