More than half of the population today lives in cities, and while we are still dependent upon agriculture for food, urban areas are almost entirely disconnected from the process of agriculture. Global trade lets us consume food from anywhere on the globe without seeing what goes on during production. In order to feed the growing world population, we need to produce more food. Challenges arise because urban dwellers do not understand agricultural production, yet they are wealthier and consume more, they consume non-local products, they have changing values, and they drive the free market system. Examples are given of food systems in Australia, Denmark, and Japan. Food affects every planetary boundary and examples are given of fun innovations to feed urban dwellers.
