Some people consider toilets dirty — their germs dangerous. But others see them as icons of health that actually save lives.
Today, a full 36 percent of the world's population lives without a toilet, says the newest data from theWorld Health Organization. That's one in three.
If even half of the 36 percent could get regular access to a toilet, thousands of children would be spared from death every year — 400,000 between now and the year 2015.
