Second Green Revolution

Guest: Jonathan Lynch, Ph.D., Professor of Plant Nutrition, Genetics and Physiology at Penn State University  The world’s population is outpacing our ability to feed everyone with current agricultural practices, says Penn State plant scientist Jonathan Lynch. During a visit to BYU’s campus, Lynch spoke with BYU Radio’s Marcus Smith about the struggles facing in countries like Africa, where water is scarce, erosion is degrading the soil, cheap sources of phosphorous for fertilizer are running out and farmers lack the expertise to improve the output of their crops. Lynch says agricultural “business as usual” will not suffice to feed Earth’s billions in the coming decades.
