I read recently of a photographic exhibition of toilets around the world. It was created by the French artist and environmental campaigner, François Cuel.
His key quote: "The exhibition is meant to make people smile but also to invite them to think. Access to proper toilets, and more generally to water, is a privilege denied to many people."
I've touched on this theme before. Dealing with the issues of waste and sanitation at our stuga has shown me how much we take our flush toilets for granted.
The Independent has an article on the exhibition, along with a few photographs, here. It's worth a look.
