The Sustainability of Human Populations: How many People can Live on Earth
- Share to:
There is nothing new about the relationship between population size and land. As early as 470 BC, Plato asserted that „A suitable total for the number of citizens cannot be fixed without considering the land…‟ The Greeks, for all their knowledge at that time, could not even begin to conceive of the vast tracts of land that existed for human exploitation. They were therefore justifiably concerned about the sustainability of their population by their limited view of what was available to them. Today, when we have come to know more fully the extent of the world and its carrying capacity, it seems that many people may have lost sight of Plato‟s wisdom. This paper sets out to place the current world population trends in the context of „considering the land‟. But first, a bit of history.
