evidence: Is Population Control a Climate Change Solution? A proposal to solve climate change by reducing fertility violates the tenets of reproductive justice—and sparks tough ethical questions. [...] When we counsel that limiting fertility (the number of children per woman*) is a necessary and sufficient solution to climate change, to whom are we speaking? It is not the already shrinking populations of wealthy nations, but those of poor nations, often in sub-Saharan Africa, where fertility remains high and arguments around "over-population" are invoked. A focus on the fertility of individuals in sub-Saharan Africa is, however, misguided.
