Water’s importance for health has been recognized across cultures and millennia and remains as relevant in the 21st century as it was in ancient Rome, when Pliny the Elder observed: In aqua sanitas
(In water there is health). According to the World Health Organization, if humankind would manage its water resources properly, ensure everyone has reliable access to safe drinking water and basic sanitation, and make basic hygiene practices the norm, we could save around 1.8 million lives yearly—mainly the lives of young children.
