In third world countries it the norm to want large families. But these are countries with little or no social programs and a high early death rate. If you live in one of these countries, big families assure parents when they get old they'll have care, since the state does nothing for them.
Truth is trying to curb overpopulation is kind of hopeless. India is one if those third world countries I was talking about, where survival for families means having as many children as possible. Its estimated that one child is born every second. As for whites now becoming a shrinking minority, For those that are racists like Trump where birth control becomes a race issue, your beliefs are being overrun by biology , nature is color blind .
The conundrum of course has science created our own doom on this planet, should we have let nature take its course in population control. Trouble is the answer to that at this point in humanities evolution comes down to race and wealth.
With scientists warning of the coming apocalyptic world due to climate change , overpopulation will be corrected by coming events. And of course the poor in third world countries will suffer the most. Its already happening in micro climate events world wide with millions dying of crop failure starvation or disease. If you're living in a first world country don't be too smug, your life or that if your children is on a destruction path also, you'll just be one of the last casualties of an overheating planet.
Overpopulation will be trumped by the coming worldwide devastation of climate change. The world as we know it is about to change in biblical terms. There will be no where to hide as the planet heats up, crops worldwide will fail, water will become more valuable than oil, starvation and disease take over. Economies already fragile will collapse like domino's. Borders will become uncontrollable ,unprotectable as the hoards of millions of climate refugees flee the killing heat of the planets middle latitudes.
We're all living in the prelude to the coming real life climate change movie. Population growth will continue for awhile, then be brutally snuffed out by coming climate change events, as our planet continues to slowly warm. We are all the frog in that proverbial pot as it heats and won't know that were all cooking to its too late.
