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?
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.
I just opened up the USSR demographic history (
https://en.wikipedia.org/wiki/Demographics_of_the_Soviet_Union). It looks like they lost about 16 million people during WWII. Other sites actually said they lost 20 million. It looks like it took them over 15 years to replenish the population after that. I not sure sure that is so fast. I do know what you mean by the baby boom though. Of course, during war people do want to have children because there is a lot of instability and danger. It's hard to say that war causes populations to grow. It is actually stopping war that lets the population grow again.
