Chapter Three: Salt of the Earth
NOTES 1. Although this particular assertion is likely a modern invention, many other examples exist. 2. https://web.extension.illinois.edu/state/newsdetail.cfm?NewsID=5427. 3. The particular parameter that measures salinity is EC. pH, another indicator tracked by SDG 6.3.2, is also highly correlated with salinity. 4. Unfortunately, data on groundwater quality is not nearly as comprehensive or as widely available; thus, impacts are not measured in this report. 5. www.worldbank.org/qualityunknown. 6. This is based on 2,000 kilocalories per day per person, or 730,000 kilocalories per person per year. 7. https://www.nytimes.com/2010/05/05/world/americas/05mexico.html.
