Girls get aborted before they're even born when there are scarce resources. This girl here, for instance, is in a feeding center in Ethiopia. The entire center was filled with girls like her. What's remarkable is that her brothers, in the same family, were totally fine. In India, in the first year of life, from zero to one, boy and girl babies basically survive at the same rate because they depend upon the breast, and the breast shows no son preference. From one to five, girls die at a 50 percent higher mortality rate than boys, in all of India. The second tenet of "Half the Sky" is that, let's put aside the morality of all the right and wrong of it all, and just on a purely practical level, we think that one of the best ways to fight poverty and to fight terrorism is to educate girls and to bring women into the formal labor force. Poverty, for instance. There are three reasons why this is the case. For one, overpopulation is one of the persistent causes of poverty. And you know, when you educate a boy, his family tends to have fewer kids, but only slightly. When you educate a girl, she tends to have significantly fewer kids. The second reason is it has to do with spending. It's kind of like the dirty, little secret of poverty, which is that, not only do poor people take in very little income, but also, the income that they take in, they don't spend it very wisely, and unfortunately, most of that spending is done by men. So research has shown, if you look at people who live under two dollars a day -- one metric of poverty -- two percent of that take-home pay goes to this basket here, in education. 20 percent goes to a basket that is a combination of alcohol, tobacco, sugary drinks -- and prostitution and festivals. If you just take four percentage points and put it into this basket, you would have a transformative effect. The last reason has to do with women being part of the solution, not the problem. You need to use scarce resources. It's a waste of resources if you don't use someone like Dai Manju. Bill Gates put it very well when he was traveling through Saudi Arabia. He was speaking to an audience much like yourselves. However, two-thirds of the way there was a barrier. On this side was men, and then the barrier, and this side was women. And someone from this side of the room got up and said, "Mr. Gates, we have here as our goal in Saudi Arabia to be one of the top 10 countries when it comes to technology. Do you think we'll make it?" So Bill Gates, as he was staring out at the audience, he said, "If you're not fully utilizing half the resources in your country, there is no way you will get anywhere near the top 10." So here is Bill of Arabia. So what would some of the specific challenges look like? I would say, on the top of the agenda is sex trafficking. And I'll just say two things about this. The slavery at the peak of the slave trade in the 1780s: there were about 80,000 slaves transported from Africa to the New World. Now, modern slavery: according to State Department rough statistics, there are about 800,000 -- 10 times the number -- that are trafficked across international borders. And that does not even include those that are trafficked within country borders, which is a substantial portion. And if you look at another factor, another contrast, a slave back then is worth about $40,000 in today's money. Today, you can buy a girl trafficked for a few hundred dollars, which means she's actually more disposable. But you know, there is progress being made in places like Cambodia and Thailand. We don't have to expect a world where girls are bought and sold or killed. The second item on the agenda is maternal mortality. You know, childbirth in this part of the world is a wonderful event.
