Before the Industrial Revolution, about half the workforce had to be farmers, just to feed the population. Even when times were good, diets were not varied and food was often not fresh. When times were hard, people went hungry and faced the threat of famine. Today, farm labor is more than 1,000 times more productive, representing only a few percent of the workforce—and we enjoy a secure, abundant supply of fresh food from all over the world.
