Thanks for this. It is incredible how drinking water is being actually wasted in some countries while somewhere even the dirty water is not available in a tap few steps far.
On the other side, sometimes the hygienic habits in certain locations are so low that people themselves defecate into water, knowing that their neighbours are in direct contact with the same water. And all of us do realize how these products can be a source of diarrhea and others.
So it is also important to prevent environment pollution.
“Uncle, you wear a tie around your neck, shoes on your feet, but you still defecate in the open. What kind of progress is this?” asks a child in one commercial. Another says: "You may have a smartphone in your hand, but you still squat on train tracks.”
It moves ahead ! :)
Actually, in Central Europe, in blocks of flats built during communism, there is usual that a drinking water is being used in Water Closets - there is simply no parallel plumbing for service and drinking water.
How good I felt when I was living in a permaculture village where we used composting toilets, instead of wasting water this way.
We are still too far to behave nicely against our natural resources and other inhabitants of the planet.
