How many people can planet Earth support? That is the thorny question that economist Partha Dasgupta tackles in Time and the Generations. Or, as he asks: “How should we evaluate the ethics of procreation, especially the environmental consequences of reproductive decisions on future generations, in a resource-constrained world?” Given that I have previously called overpopulation the elephant in the room that few wish to address, my interest was immediately piqued.
Speaking of controversial. As mentioned in my previous review of An Essay on the Principle of Population: The 1803 Edition, concerns about human overpopulation go back to at least Malthus, a name that has become synonymous with this topic. How do you tackle this incredibly thorny issue? Malthus believed moral restraint where having children is concerned should be encouraged, which strikes me as starry-eyed and completely out of reach, especially in the individualized societies of today. Simultaneously, we have seen some pretty drastic population control measures with ugly side-effects, such as China’s one-child policy and forced sterilization in India. The cry of eugenics if never far away when this topic is tabled. Can we have any sensible discussion to find a middle ground between utopia and dystopia? This small book does a serious attempt.
