世界厕所峰会(2)

In October 2007, people from forty different countries met in Delhi, India. They met to talk about toilets. Many people may not think that toilets are a very important subject to discuss.

But, the people attending the World Toilet Summit disagree. They believe that toilets are an important part of good health.

And they know that over two billion people are without toilets. That means that over two billion people are at risk of infection, every day.

You see, human waste is made of mostly two things, water and dangerous organisms like bacteria. These organisms can cause different diseases - if the organisms enter a person's mouth.

In fact, many diseases are spread through human waste. These diseases include food poisoning, diarrhoea, cholera and typhus. These are all deadly diseases.

In fact, the United Nations estimates that every year over two million children die from diarrhoea and other diseases caused by human waste.
