Did you know that nearly half the world's population has no access to a toilet of any kind and has to relieve themselves of their bowels and bladders by squatting in a field?
I'd laugh, but I'd be a hypocrite. A mere four generations ago, my great grandfather is on record as refusing to allow a toilet in his house, on the grounds that toilets inherently smell (as the outhouse that he used did), and that having it in the house would stink up the entire house.
But, as the article shows, many people lack even that. They have a bucket, that they empty into a field while no one's watching, or worse, have to squat in the field and hope no one bothers them in the process. Not good for hygiene (that field is going to stink) or health (bandits are a problem in these kinds of countries -- it wouldn't surprise me if they learned to harass people in the field, so to speak) or the environment (these fields are often very close to rivers, or even in them). Ick.
Apparently a number of charities are working hard to dig outhouses, the kind my great grandfather used, in these places so that people will have a safe, clean (if unbearably stinky), non-polluting place to do their business, and this makes a major difference.
Bonus if this also somehow fertilizes the nearby farms. (I've heard mixed reviews as to if that would work.)
