      Great question – the basics of it all!

      We need toilets to contain human waste. Its not healthy if its all over the place (as you can imagine!)

      The big risk is that somebody might ingest it somehow – the waste might get into their water source, or they might get their hands dirty and put them in their mouth or on their food.

      The main purpose is therefore to separate humans from their waste to keep them healthy.
