We (husband and I) have now lived on this planet for over a half century. I had two children. My friends who had children generally had one or two, also. Across the first world nations run mainly by Protestant-derived religions have seen the swift rise of family planning. My mother had seven children and we hated each other a great deal. In Muslim and Hindi regions we have out of control births unlike say, China, which has rapidly moved into the ring of first world nations after getting its massive population under control. The places where it is illegal or impossible to have birth control such as Catholic controlled nations, are also feeding this out of control population boom that is now assailing the first world as excess population struggles to survive while the underclass in first world nations also give birth frequently since this increases welfare payments.
The harsh truth is, the earth isn’t this eternal entity that can handle a doubling population of any creature to eternity. There has to be limitations. These come in various forms, generally, population collapses like the sort which hits rodent populations during wet, warm years which collapses during cold, dry periods, for example. No living entity can go forever reproducing endlessly.
Humans have conquered many diseases like the infamous Black Plagues which wipe out a third to half all humans in its path. With modern vaccinations, huge swaths of third world areas have enjoyed massive population booms with the occasional epidemic killing less than 10% of the population at any given time.
Europe is being overrun with refugees whose ultimate reasons for fleeing is due to collapsing political situations which existed on the edge of the population sword especially formerly socialist countries like Syria, Libya and Iraq all of which provided seriously well-run health and welfare systems that caused huge population increases unlike much of Africa which has little to no services.
The Catholic nations south of the US border have the exact same situation with several socialist-leaning nations producing many children due to lack of birth controls thanks to the Vatican who wants infinite humans to die and go to Heaven and which actively plans for all humans to be finally annihilated via the Apocalypse which they do everything to encourage.
The US won’t push for birth control nor will Europe turn and face the out of control nations that have no excuse for overproduction of children they can’t feed, care for or help. Instead of using modern methods to provide a better life for fewer offspring, they make it deadly dangerous for any woman to control her womb, they will murder women who try to control their production of children rather than free them to live full lives and have a sensible number of children to love and nurture. Instead, they are worked miserably to death (I nearly died having my second child!) and they die young, worn to the bone, with unhappy children begging for the barest things to survive.
The UN should address this. But cannot thanks to all the miserable, evil god created by humans these death gods being delighted in murdering us periodically or annihilating us entirely. Who could possibly love these creatures? Not I.
