By: Mark Leon Goldberg on February 04, 2011 Good stuff from Nancy Gibbs in Time: We know what the birth of a revolution looks like: A student stands before a tank. A fruit seller sets himself on fire. A line of monks link arms in a human chain. Crowds surge, soldiers fire, gusts of rage pull down the monuments of tyrants, and maybe, sometimes, justice rises from the flames. But sometimes freedom and opportunity slip in through the back door, when a quieter subversion of the status quo unleashes change that is just as revolutionary. This is the tantalizing idea for activists concerned with poverty, with disease, with the rise of violent extremism: if you want to change the world, invest in girls. In recent years, more development aid than ever before has been directed at women–but that doesn’t mean it is reaching the girls who need it. Across much of the developing world, by the time she is 12, a girl is tending house, cooking, cleaning. She eats what’s left after the men and boys have eaten; she is less likely to be vaccinated, to see a doctor, to attend school. “If only I can get educated, I will surely be the President,” a teenager in rural Malawi tells a researcher, but the odds are against her: Why educate a daughter who will end up working for her in-laws rather than a son who will support you? In sub-Saharan Africa, fewer than 1 in 5 girls make it to secondary school. Nearly half are married by the time they are 18; 1 in 7 across the developing world marries before she is 15. Then she gets pregnant. The leading cause of death for girls 15 to 19 worldwide is not accident or violence or disease; it is complications from pregnancy. Girls under 15 are up to five times as likely to die while having children than are women in their 20s, and their babies are more likely to die as well. Read on. And head over to Girl Up to pledge to unite for girls.
