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.
