One life is worth no more or less than any other

The biggest pieces of work that we do are vaccines, because those save lives, and also family planning. Because if a woman can space the births of her children, it changes everything for her health and her child's health.

In the developing world, it's about time that women are on the agenda. For instance, 80 percent of small-subsistence farmers in sub-Saharan Africa are women, and yet all the programs in the past were predominantly focused on men.

Women and girls should be able to determine their own future, no matter where they're born.

If you don't invest in the woman, empower her, give her the things she needs to lift her family up, you're just not going to make the progress that you want to make. But if you put her at the centre, you can change a lot for that family, and it has ripple effects through the economy.

Even in our own agriculture strategy, if we got a great new drought-resistant seed and we managed to get it distributed in the system, we just assumed that it would reach female farmers. That's a false assumption, because women don't interact with agro-dealers. So if you don't develop specific programming to ensure that seed gets in a woman's hands, then the extra income [generated by higher-yielding crops] goes into her husband's hands.

Childbearing, I mean, if there's no place to go to deliver your baby, then you're the one that's delivering in those unhealthy circumstances. Or if you can't get access to family planning, your chances of surviving and being able to bring your kids up if they come one right after the other, that locks you into a cycle of poverty.
