1. The Human Drift - Details over-population and the human need for space, but notes how when food production became easier and more reliable population grew as a result - erasing space. Predominantly based on Thomas Malthus' principal that while population grows with food availability there exists a carrying capacity that will cause a natural check on man - much like war, natural disaster and pestilence already do in over-populated countries. The truest to London political views (5 stars).
