Babies according to this article.
Of course the article has the solution. It's simple:
One strategy is to reduce the birthrates and the mortality rates of infants and younger children, according to Population Action, which hopes its research will improve contraception programs, education for girls and health services for children and pregnant women.
Not only is it bad but wait until you read this:
Almost a billion people live in countries where birthrates average at least four [oh the horror] children per woman, among them, Nigeria, Afghanistan, Iraq, Pakistan, Somalia and Sudan. Those countries need help to improve infant and child survival and the educational status of women, to reduce population pressures and to become more stable, the report says.
G.K. Chesterton recognized this argument as pure capitalism also known as greed. He wrote an essay called On Social Reform versus Birth Control:
What he (the Birthcontroller) wants to control is the populace, and he practically says so. He always insists that a workman has no right to have so many children, or that a slum is perilous because it is producing so many children. The question he dreads is "Why has not the workman a better wage? Why has not the slum family a better house?" His way of escaping from it is to suggest, not a larger house but a smaller family. The landlord or the employer says in his hearty and handsome fashion: "You really cannot expect me to deprive myself of my money. But I will make a sacrifice, I will deprive myself of your children."
