For example, desert village in Middle and Near East.
They have 10L water for drinking and washing their hands, 　

8L for laundering, and 7Lfor cooking.
25L water is as much as 10% of Japanese people’s average.
Let’s see the life of people facing more sever water shortages.
For example, West Africa.

They have only 4L water for drinking and washing their hands, 1L for cooking.
When we turn on the tap for less 30seconds, we use 5Lwater.
We don’t write about water using for toilet and bath.
Because there is not toilet and people who live in Middle Near East and in West Africa take a shower in the river.
Living West Africa people cannot so much as laundry.
