Any discussion of “population explosion” must include some kind of analysis of how many people the planet can actually hold. Remember they all have to go to the bathroom every day. It is not about land area as EC commented, rather it is about rainfall. The discussion has always been poisoned by leftist propaganda, so it is natural to recoil from the subject, but I still wonder.
the Earth can hold trillions of people because more people leads to greater economic growth. Economies and scale are created and labor specialization is increased, and this all leads to more human ingenuity, the greatest factor contributing to human flourishing.
