I have to agree that the world is vastly overpopulated. It's obvious. It's also obvious that most of the problems people whine about (global warming, pollution, plagues etc.) wold be greatly alleviated if our population was much smaller than it is now. Most educated people instinctively know this - and it may explain why developed societies are seeing fewer kids.
It's obvious that a finite ecosystem cannot support infinite population growth. In the wild, when a species overpopulates, it dies off. We are overpopulated. Absolutely.
Now, what scares me is that a billion other people know this too. And all you need are a couple of them with the skill and the means and the necessary psychopathic traits to decide to speed the process up - for the good of humanity, of course. Like pruning a tree.
If that happens, you won't see it coming. And it won't require a widespread conspiracy of 100s of people. Only a handful can pull it off. That's the scariest part.
The Covid vaccines ain't it. And whatever it is, it will be something that kills off vastly more poor people than rich people. Because that's how these things work, whether it's nature or a psychopath with a deadly virus.
