Gender-based violence victimizes one out of three women worldwide. Sixteen Days of Activism against Gender-Based Violence challenges every man and woman to take action to end this worldwide scourge.

Under the banner of “Ambassadors for Change,” 14 female heads of diplomatic missions and international organizations in Bangladesh joined forces to convey the urgency of eliminating gender-based violence. Also lending their voices were Shirin Sharmin Chaudhury, Bangladesh’s speaker of Parliament, and Bangladeshi cricket captain Mashrafe Mortaza.

Their message: “One of the most important ways to change the lives of women and girls is to have the men and boys in our lives stand with us.”

You too can be an ambassador for change. The U.N. invites you to “Take action to Orange your world” and take part in other activities to show support.
