About this talk
Norman Borlaug (1914-2009), the "father of the Green Revolution," is said to have affected more people's lives than any one human in the 20th century, and yet he has almost no name recognition. In the 1960s, Borlaug led the scientific crusade to breed high yielding wheat, which required prodigious applications of synthetic fertilizers. In this lecture, Dr. Tim Crews sets the achievements of Norman Borlaug in context by exploring how humanity managed soil fertility before Borlaug's Green Revolution, and he unfolds some fundamental sustainability challenges facing humanity in Borlaug's wake. In the conclusion, Crews addresses whether organic agriculture can feed the world.
