LOL, did the surviving children of Thanos migrated here from Reddit?
Really? A whole strange lot on here. So many people seem to be in support of war. I had to actually pinch myself to be sure I wasn't dreaming. Wars don't reduce population only. They also reduce infrastructure and resources. What does this imply? It means we are always back to square one or even worse. I have a question of mine. Why is human population we need to reduce. Why not increase our productivity?
I view it as like increasing food supply, you make more food available, you allow the population to grow even larger. Only being a truly circular economy (everything gets recycled back) could ensure we never run out of resources and we're still far away from that. Hence why people are suggesting reducing population instead to buy us time.
Wars actually cause an increase in the population. Check the population charts of countries such as Russia and Germany which suffered the most from WW2. There was a sudden spike immediately after the war was over. War is never the solution for anything.
Probably depends on how many people die off in an event. Europe lost a quarter to half of its population due to plague and it took centuries for it to recover, enough time to make the survivors' descendants a bit better off.
