This is no toilet joke.
According to a new study published by¬†Environmental Science & Technology, about sixty percent of the world does not have access to a flush toilet or equivalent.
That's about 4.2 billion people (we know what you're thinking -- "holy crap.")
What happens to these people without toilets? Hookworms,¬†dysentery, cholera, hepatitis A, and severe (deadly) diarrhea, which causes more deaths than AIDS in Third World countries.¬†Thankfully, brilliant minds from Caltech invented this solar-powered toilet last , costing users just five cents per day.
So¬†the next time you take a bathroom great, be grateful that it's a¬†porcelain¬†throne instead of a dirt hole.
