The researches estimate that the carbon legacy of the average female in the United States is 18,500 tonnes of CO2 while that of a Bangladeshi woman is only 136 tonnes.
In other words, the future stream of carbon emissions following a decision by an American couple to have an extra child is 130 times greater that of a decision by a Bangladeshi couple.
Put another way, to have the same impact on future global carbon emissions, a decision by one American couple not to have a child would have to be matched by 130 Bangladeshi couples.
Therefore it makes no sense to single out population growth without linking people to their expected consumption.
Recognising that it is affluence rather than population growth that is mainly responsible for the climate crisis allows us to recast the famous Malthusian theory.
