The 20th century is remarkable for bloodshed and lives lost through the madness of men. Stalin and Mao created environmental ruin and starved around 40 million. Exploding populations post-World War II caused Paul Ehrlich to write in his book Population Bomb, “The battle to feed all of humanity is over.” Ehrlich warned that only government action to force curbs on population would prevent massive destruction of the environment, and hundreds of millions dead. Unlike Ehrlich, Norman Borlaug did something positive for the world. He developed genetically modified high-yield rice and corn, which ignited the “Green Revolution.” This lead to development of hybrid grains capable of handling varying climates and prevailing diseases and increased crop yields over 700 percent.
