A day dedicated to toilets for cleaner world

A toilet is built in the form of a camera on the street of Chongqing. November 19 is Worlds Toilet Day and this year's theme is When Nature Calls. The United Nations says: ""When nature calls, we need a toilet. But, billions of people don't have one. This means human feces, on a massive scale, are not being captured or treated – contaminating the water and soil that sustains human life. We are turning our environment into an open sewer. We must build toilets and sanitation systems that work in harmony with ecosystems."[Photo: VCG]
