Give girls dignity

About 1.8 billion people across the world menstruate each month. 

But millions still don't have access, to something as basic as sanitary pads.

It also means that as the world marked Menstrual Hygiene Day today, somewhere in South Africa there were young girls who skipped school because of this avoidable reason. 

So just what's needed in order to ensure the dignity of all girls is protected. 

 We ask this question to Sue Barnes, the founder of the Dignity Project.
