I would name it "The power of water"
In photo above a young girl is offering handful sips of water to her brother from gutter (Khaal) sort of open sanitary system for irrigation used in south Asia. No doubt this water is full harmful bacteria and chemicals.
"Water is a fundamental human need. Each person on Earth requires at least 20 to 50 liters of clean, safe water a day for drinking, cooking, and simply keeping themselves clean yet 844 million people in the world - 1 in 9 - lack access to it.
Polluted water isn’t just dirty—it’s deadly. Some 1.8 million people die every year of diarrheal diseases like cholera. Tens of millions of others are seriously sickened by a host of water-related ailments—many of which are easily preventable.
The United Nations considers universal access to clean water a basic human right, and an essential step towards improving living standards worldwide. Water-poor communities are typically economically poor as well, their residents trapped in an ongoing cycle of poverty.
Education suffers when sick children miss school. Economic opportunities are routinely lost to the impacts of rampant illness and the time-consuming processes of acquiring water where it is not readily available. Children and women bear the brunt of these burdens.
Water is obviously essential for hydration and for food production—but sanitation is an equally important, and complementary, use of water. A lack of proper sanitation services not only breeds disease, it can rob people of their basic human dignity.
According to a report by the World Economic Forum, the water crisis is the #5 global risk in terms of impact to society."
