A 2007 Indian government study found that 53 percent of children in India faced some form of sexual abuse growing up.

That is why, in December 2016, I joined a diverse group of Nobel laureates and global leaders to launch the "100 Million for 100 Million" campaign. One of the campaign's objectives is to persuade, provoke, and inspire 100 million young people around the world to raise their voices against violence inflicted on children.

So on Sept. 11, I will embark on a bharat yatra (political pilgrimage), traveling across India to declare war on sexual abuse and exploitation of children everywhere.

More than 10 million people are expected to join me physically and virtually on a march that will traverse 11,000 kilometers, touching all corners of India in a bid to raise global awareness.

It was the culmination of the Global March Against Child Labor, and more than 15 million people had joined us by marching some 80,000 kilometers through 103 countries.

The world needs a similar effort against child sexual abuse and trafficking.

Let us be inspired by them, and wage a humanitarian war against child sexual abuse.
