This book looks at the comparison between the way the West treats fertility in terms of its female population and its agricultural produce. Diamond suggests that the West is obsessed with "control" and regulation when it comes to fertility: control over manor and quantity of the soil's produce and control over the production of human babies. She looks at the way in which the birth control pill has gone from a tool of women's liberation to a tool of regulation and control by doctors and compares that to the way genetic modification, pesticides and fertilizers regulate our agricultural market. What we don't have, Diamond argues, is a society that trusts in either the Earth or individual women to exert adequate, unaided authority over their own (repro)duction.
