Women and children across the world will move their hands and feet tonight.
As they dance, they hope to move a message as well: Put a stop to violence against women and children.
The global movement is called One Billion Rising: No Excuse for Abuse. The name derives from data that indicates 1 in 3 women on Earth will be beaten or raped in her lifetime. With a world population of 7 billion, this adds up to more than one billion abused women and girls.
