I long ago conceded on this blog, indeed I have never believed, that "overpopulation is the cause of hunger and poverty in the world."
I cannot speak to Filipino agricultural land levels but I've read that there has been enough food grown worldwide to make every man, woman, and child overweight. So "overpopulation" isn't anywhere close to being the cause of food shortages in modern times. [my emphasis--DJB]
Yes poor people have more children. Its partly because children grow up to be laborers who help the family when older and also partly the shotgun approach to making sure a children survive.
For a lot of social problems I tend to look first to those wealthiest in a society as their control over resources that define how well (or badly) a society develops).
And I'm not ready to say population levels are a problem when the point I just mentioned seems to be so overpowering in comparison to everything else.
An irony is that those with the wealth may look to use population level as a scapegoat for problems that I doubt are do to it.
Indeed China and India support populations that are far larger than that of the Philippines, though no doubt ancient memories of war and famine goad them to prudential endeavours involving both production of food and the limitation of reproduction (sometimes using means unacceptable to most of us.)
But there are indeed many causes of suffering in this world. Yet in choosing what problems any society is to solve first and what solutions to apply, we ought to have a choice in the matter -- that is my first belief. However, on the matter of birth control methods that do not involve abortion or genocide, it seems to me that whatever evil we may perceive in them cannot possibly outweigh the undeniable effects of population numbers that cannot decently be sustained by that society, even if we were to agree that other causes can and ought to be dealt with as well. In the present growing crisis, who will deny that whatever problems of want and need we suffer from, they are mightily multiplied by the fact the degrees and magnitude of them could've been avoided if only such institutions as the Roman Catholic Church and the government had discerned the wisdom of prevention and chosen it over the necessity of adopting what will surely be insufficient, if not draconian measures to now address those problems. Whatever one may think of those other causes, the problems are multiplied by overpopulation and whatever solutions and gains upon them we can imaginably make, will surely be diminished by the awesome denominator of 90 million instead of more prudent Thailand's 66 million!
How can any humane person, anxious for the welfare and well-being of his neighbors continue to urge that we hide our head in the sand and wait yet another Doubling Time, by when these terrible scourges of hunger and poverty shall have been exponentiated by such willful neglect of the obvious.
