James H. Brown has written a fascinating essay that explores how energy consumption correlates with rate of births per year for both humans and other animals.

While it comes as little surprise that birth rates are lower in more economically developed countries, Brown argues that patterns of energy use and fertility rates are similar to those found in other mammals:

Our non-biological energy use appears to affect our birth rate the same way that biological energy use affects the birth rate of other primates.
