of the human population on planet Earth:
How many humans can planet Earth support? The answer depends on assumptions you make about human diet, waste production, resource use, what constitutes a 'reasonable' standard of human living, and about the need to protect planetary ecosystems and biodiversity for their intrinsic values and for future generations. Many studies (both scientific and non-scientific) have looked at this issue. There are different answers. In my view, planet Earth over-shot its carrying capacity for humans towards the close of last century; probably some time between 1970 and 1990.
If you wish to think about this issue, and form your own opinion, I believe it's essential to consider the following:
