The Bill and Melinda Gates Foundation announced recently that it will invest more money into improving sanitation services in poor countries around the world.
$42 million dollars will be added to an ever increasing budget that aims to encourage innovation and focus on a basic human need that is oftentimes overlooked. Even the original eight Millennium Goals drawn up by the UN back in 2000 did not include improvement of sanitation.
However, sanitation is a big problem. An estimated 2.6 billion people lack access to safe sanitation. One billion people defecate openly. Diarrhea is the number one killer of children in Africa, which can easily change if sanitary practices are improved. If we keep going at our current rate, by 2049 only 77 percent of the world population will have flushable toilets.
