An inflatable toilet set up by the UN is on display in front of the UN headquarters in New York, on Nov. 19, 2014, to mark the World Toilet Day. With one out of three women worldwide lacking access to safe toilets, it is a moral imperative to end open defecation to ensure women and girls are not at risk of assault and rape simply because they lack a sanitation facility, UN Secretary-General Ban Ki-moon said Wednesday.
