It's an excellent piece. I'll admit to being a bit confused by the assertion, however:
> "letting children die now so they don’t starve later—doesn’t actually work, thank goodness. It may be counterintuitive, but the countries with the most deaths have among the fastest-growing populations in the world. This is because the women in these countries tend to have the most births, too."
I spent five months in Kenya, and a couple weeks with the Samburu tribe during a drought. All their animals were dead, piled up, because there were no more leaves to eat. We were driving a caravan of food to distribute in the region, since otherwise the people would have been next. And the dilemma was explained to me clearly: we can't just let people die. But it means we have to send food aid all the time now, unlike decades ago, because the population is simply larger than the land can support, except in its best years, and it makes the people essentially permanently dependent on outside aid.
So I'll admit to being stumped by what Melinda Gates means when she says that overpopulation isn't the result of aid. Simply asserting that "countries with the most deaths have among the fastest-growing populations in the world" doesn't explain anything -- it's just a correlation, and might very well be due to the fact that such countries already receive the most food aid, for example.
I'm certainly not arguing that I am against, or that anyone should be against, food aid. But I am utterly unconvinced by Melissa Gates saying that "saving lives leads to overpopulation" is a myth -- she doesn't substantiate it, and it seems like the weakest part of the whole post. It all depends on how you define overpopulation, but I just don't see it yet. Of course, rising income and education lowers birth rates in the future, but that doesn't change the simple fact that, at low levels of income and education, more food aid directly results in more people, which is often more than traditional local practices and agriculture can reliably and sustainably support.
