On November 19th , the UN organizes a special day to talk about toilets.

You know toilets! That’s where you go to pee or to poop.

For peace and quiet, you shut the door and you do what you have to do.

When you’re done, you flush the toilet and the excrement goes down the sewers and off to the water treatment plant.

Here, the waste water is treated. Once clean, it can be released into rivers.

But why do we need a special day to talk about toilets?
