Gaia Doesn’t Care where your Baby Comes From

Guest Post by Dominic Wilkinson, Associate Editor, Journal of Medical Ethics

In a provocative paper published today in the Journal of Medical Ethics, US theologian Cristina Richie argues that the carbon cost and environmental impact of population growth in the West should lead to restrictions on artificial reproduction.  She points to the substantial carbon emissions that result from birth in developed countries like North America.  Seven percent of the world’s population contribute fifty percent of the world’s CO2 emissions, and children born by in vitro fertilization are likely to be in this seven percent.  Richie argues in favour of a carbon cap on artificial reproduction and argues that IVF should not be funded for women who are “biologically fertile”.

Richie is correct to point to the enormous carbon cost of additional human population. One of the most significant ways that individuals in Western countries can reduce global carbon emissions is by having fewer children. However, her focus on artificial reproduction and on the “biologically fertile” is not justified.

Richie ignores questions about the moral implications of climate change and climate cost for natural reproduction.  She sets to one side “the larger realm of sexual ethics and procreation”.  Yet there are two reasons for thinking that this is a mistake.  First, as Richie notes, “Reproduction-related CO2 is primarily due to choices of those who have children naturally: a huge majority of all births.”  Only 2% of all children born in the UK are conceived by IVF.[1]  Therefore interventions to reduce the number of children naturally conceived will potentially have a fifty fold higher impact on carbon emissions.
