With climate change already close to an irreversible tipping point, urgent action is needed to reduce not only our mean (carbon) footprints but also the "number of feet" -- that is, the growing population either already creating large footprints or aspiring to do so, argues a leading physician and environmentalist in The BMJ.

Yet John Guillebaud, Emeritus Professor of Family Planning and Reproductive Health at University College London, says most climate change discussions focus only on technology and consumption.

He points out that 45% of the world lives in areas where total fertility rates range from 2.1 to 5, and 9% where they exceed 5. In the 48 countries designated by the United Nations as least developed, population is projected to triple by 2100.

The UN's latest median world population projection of 11.2 billion by 2100 is predicated on continuing reductions in fertility rate, he adds.  Without them, the constant fertility variant projects to roughly 28 billion by 2100.

Studies invariably show that family planning is highly cost effective compared with other emission abatement strategies, he explains.
