Mallika Dutt and Sonali Khan have an ambitious goal: to mobilize an entire generation to put an end to violence against women — and men are at the heart of their campaign.

Their organization Breakthrough works in the United States and India, deploying a mix of social media, pop culture and multimedia campaigns to challenge the deeply held cultural norms they see as the root of the problem.

The scale of the issue they are trying to address is huge: 1 in 3 women will experience sexual or physical violence, and in some countries the figure is as high as 70 percent, according to the United Nations.
