There are many ways to define prosperity. For some, it is all about money in the bank; for others, it is about health, spiritual well-being, or happiness. But because humans are animals, all of these definitions in the end come down to the same thing: energy flows. Unless we each consume about two thousand kilocalories of energy each day from food, plus more for fuel and shelter, we will sicken and die.
