Every year, November 19 is celebrated as the World Toilet Day to tackle the problem of open defecation across the globe. The idea of dedicating a day to toilets came to Jack Sim, Singaporean businessman in 2001, reason being, loss of lives and money due to poor sanitation. Since then, every year, the day is celebrated with a unique theme and this year the theme is 'When nature calls, we have to listen and act.' The theme urges people to use toilets, especially nature-based sanitation solutions like composting toilets that treat human waste and convert it into fertilisers.
