The global population, currently at 8.2 billion, is projected to reach approximately 10.3 billion by the mid-2080s and then gradually decrease to around 10.2 billion by the end of the century, according to the U.N. report on world population prospects released last month.
2 billion more people than we have now isn’t much of a decrease… I don’t know about maintaining that trend long enough to actually decrease from what we have now, which is already overpopulated.
