What has made the most difference in life expectancy over the past three or four centuries? Better medicine? Healthcare? Food and nutrition? These all help, but don’t ignore the role of geosciences and engineering in providing safe drinking water. In fact, potable water supplies and effective sanitation systems may be the most important factors in improving life expectancy community by community and country by country. Thank God for water, and for water that is fit to drink!
