They do not drive SUVs. Some have never even seen a light bulb. But according to research one of the most effective ways of preventing climate change is to ensure that poor women in the developing world do not have a lot of children.
Because of their advertised positive impact, I used to be a proponent of
population control family planning programs in the developing world. And then I saw the data and changed my mind. Reducing the number of people being born in the developing world will not reduce the effects of climate change. What needs to happen is a change in consumption habits in the West and among the upper classes in the developing world. The poor too need to stop cutting down trees for charcoal. But we should not push them into having less children and make it a climate change issue. They are not responsible. Those responsible should change their consumption habits and perhaps invest in providing alternatives to charcoal for the poor.
