"Teaching the hungry how to more efficiently farm, can actually create new unexpected inefficiencies. The Green Revolution in India, in which farmers in the Indian state of Punjab switched from traditional methods to American-style farming - with chemicals, high-yield seeds and irrigation- was once thought to be a rousing success. However, under scrutiny the shiny label of success has lost some of its sheen: India's Green Revolution has depleted ground water, destroyed soil through salinization, locked farmers into cycles of debt and turned what was once a localized hunger problem into a structural one. It also hasn't actually solved India's hunger problem: 1/4th of the world's hungry call India home. A whopping 230 million people or 18% of India's 1.25 billion population is hungry"
