When I born (October 1945), the estimated world population was approximately 2.3 billion which is about the estimated carrying capacity of our planet (2.5 billion). Today there are over 8.3 billion people.
I've stated many times that the first part of most any problem you want to discuss is that there are too many people. You can discuss all kinds of environmental, economic, social, political, etc issues but nobody wants to address the real problem of too many humans breeding too much and now living longer than ever.
There are not any good answers to this problem. Nor could we find common agreement on any, if there were. The only outcome I can see is some major calamity.
