Yes, population grew for a reason: lack of wars and increased healthcare.
It's not just that. When I add up the powerful reproductive urges most all humans feel + the so many compelling reasons why parents have as many children as they do, what I come up with is a collective GLOBAL natural desire, to ENLARGE the entire human race, for the greater good of the many. So it's not just individual rights, but also the collective good that argues for naturally EXPANDING the size of the human race. And did I mention that God still commands humans to MULTIPLY?
With whatever that supposedly might keep human populations more "in check" fast fading away, and increasing awareness of the deception and bad motives underlying the rampant pushing of shoddy Big Pharma contraceptive potions and poisons, it's all the more reason to EMBRACE allowing the human race to naturally grow ever larger and denser, as God would allow.
Blessed are the peacemakers. Sure, liberty is worth fighting for, but if wars can be prevented, why not?, since wars cause needless suffering. Wars generally have not been effective at population "control" of humans anyway, because they often destroy resources and infrastructure so much more so than the burgeoning numbers, and a population under stress finds it all the more "patriotic" to breed up their numbers prolifically, perhaps partly as a way to "fight back" against their enemies.
You also said increased health care. I prefer to call it medical care, because the overpriced medical Big Pharma industry is more into expensive questionable treatments than into promoting actual good health. Not just medical care, but improved public sanitation. It was good to have "modernized" things, not just in replacing outhouses with indoor flush toilets, but also electrifying cities and villages, to replace millions of crowded urban smoky cooking fires, with clean natural gas and electric cook-stoves. Do you think such inventions are just for our selfish convenience? No, I find the real purpose, perhaps even reason for invention of such things, is to grow human populations ever larger and perhaps denser as well, as may need be. By expanding suburbs on top of suburbs, and building more cities and towns, letting cities and towns grow larger and closer together, place may be found or made, for everybody and their progeny. Let people go on having their precious darling babies. Each and every human life is sacred, and we ought not to impede the natural spread and beautiful BLOSSOMING of human life throughout the world.
I believe in neither imposing population "control" nor awful unnatural "birth control" upon humans. It's good for children to grow up in traditionally VERY LARGE families. Growing up in a LARGE family better conditions children not only to be less selfish and think of other people, but to not only survive but also thrive in an increasingly populous world. Letting large numbers of families go on growing naturally, better respects the dignity and immense value of each and every human life, and also respects the body's natural reproductive rhythms which ought to be EMBRACED rather than fought. Whatever happened to counting children as a blessing from God, and accepting that babies happen as they happen? Until very recently, most everybody was expected to marry fairly young and produce children. Then women decided they wanted to be men, birthrates plummeted, societies turned more disfunctional and evil and corrupt and selfish, and now the Muslims are taking over the world, because they, for some reason, still reproduce like rabbits, while too few non-Muslims still obey God's commandment to people to Be fruitful and multiply and fill the world.
As world population naturally rises, why can't my possibly many children, be among the "meek to inherit the earth?"
