Today I want to focus on Water and Health (my fellow FPA blogger, Bill Hewitt, has something to say on the environmental front as well). The UN has dubbed March 22nd World Water Day, and in my reading I stumbled upon a pretty amazing statistic. According to the World Health Organization, each $1 that we invest in clean water access gets returned to us 3-34 times in time savings, productivity, improved education and reduced healthcare costs. Compared to the majority of social investments – which often achieve only a 1:1 return, and very frequently, less – this is phenomenal. In terms of “social return”, improved access to clean water is clearly a sound investment.
