A vital resource for us all. The so-called developed countries have a running water distribution network, water flows directly from the tap. Others have inherited elaborate fountains and systems like those still used in medinas. Some in arid areas have to travel kilometers to access this basic resource. This young Mongolian child will "only" have to pull the gallon of water needed to run the household on his trolley for several hundred meters. It is a daily task that remains unchanged for this ancestrally nomadic people, despite a way of life that is gradually becoming more sedentary. Their environment has changed but some tasks remain the same. I wonder: is the lifestyle they embrace more comfortable than the one they leave behind? A very complex question with multiple answers.
