World Toilet Day! Sounds amusing - but there is far more on it than that!
A significant part of the world's population has no access to sanitary facilities and clean water. The missing facilities are one of the reasons why sanitary conditions are often catastrophic and basic hygiene and the prevention of infectious diseases becomes almost impossible.
But openly lying waste and defecation poses not only a high risk of infection. They are a major problem for groundwater and drinking water supplies.
To make this problem clear to the public, the United Nations officially proclaimed the first World Toilet Day on Nov. 19, 2003.
In addition to the development of local sanitary supply and disposal systems, there are also unusual approaches to solving the problem.
"Peepoos," for example, are compostable bag toilets invented by a Swedish urban planner in 2009. A worth reading report on this project can be found on the pages of Deutschlandfunk.de.
