World Toilet Day

When I heard today that it is World Toilet Day, I thought it was a joke.
But than I learned that this day has a serious reason:
Since 2012 the World Toilet Day (WTD) is an official United Nations international observance day on 19 November to inspire action to tackle the global sanitation crisis. Worldwide, 4.2 billion people live without "safely managed sanitation" and around 673 million people practice open defecation.
Having to defecate in the open is especially difficult for women and girls. Women tend to resort to the cover of darkness to give them more privacy, but then risk being attacked when alone at night.
It has been estimated that 58% of all cases of diarrhea worldwide in 2015 were caused by unsafe water, poor sanitation and poor hygiene practices, such as inadequate hand washing. This resulted in half a million children under the age of five dying from diarrhea per year. *Wikipedia, see also for more information
