Today, there are more than 7 billion people on the planet. And although undernourishment remains an issue for about 11 percent of us, it’s not because we fail to produce enough calories. Poverty determines whether people get enough to eat. But on this front, too, there is hope. Food is becoming cheaper in most countries, including developing countries, where food has traditionally made up a higher portion of the average family’s income. During recent decades, the downward trend of these lines indicates a massive rise in the global standard of living. In particular, China and India, which represent a significant part of the world’s population, have seen dramatically lower food costs relative to income.
