But if the disease had been bubonic plague, then outbreaks in the human population should have been preceded by extensive deaths among local rodents.
The question “How many people can the Earth support?” is useful, though it is seriously incomplete. It focuses attention on the present and future numbers, qualities, activities, and values of humans in their relations with one another and with the Earth. To explain why people are interested in this question, …
