Choosing to have children is a private decision with global consequences. Other Than Mother explores the decision-making process around not having children. It is in three parts: Part I "The Worldly Winds" explores the backdrop to deciding whether or not to have children, including the cultural changes brought about by a rise in voluntary/intentional childlessness. Part II "A Private Decision with Global Consequences" explores the pros and cons in the decision-making process, including ecological and environmental considerations. Part III "New Horizons and Baby-sized Projects" explores living with the decision.
