Overpopulation is literally the single most important problem for this planet.
Yet somehow literally every single ideology leads people to scream in fits of rage at everyone who tells them this.
- rightwing extremists say it leads to white genocide
- leftwingers say you are some kind of racist because you want less brown people to be born
- normies say it is all a lie and will inevitably balance out at 10 billion (as if that isn't way too much already)
- traditionalists/christians and some others want to pursue their personal dream of having 10 children and don't care about the picture at large
It's why the ecosystem of this planet will collapse or at least radically change radically worsen the living conditions for the human species. Humans in general might survive in greatly reduced numbers, civilization will certainly not.
If we opened our eyes we could prevent this catastrophe by strategic planning, but with the dumb majority of people this is not possible. We are driving our car full speed against a wall and some with open eyes are along for the ride, seeing the disaster, while everyone else has their eyes closed.
