Details of How many people in the world don’t have toilets;
Oilets were created in Scotland around 3,000 BC, and John Harrington Queen Elizabeth’s first godson created the flush toilet in 1596. Due to improved hygiene, toilets have saved millions of lives. However, 2.5 million people die each year from a lack of toilets, and 3.6 million people worldwide lack access to a functional toilet. This is because plumbing is expensive; just in the US, maintaining it costs 70 billion dollars.
