Joseph L. Shaefer submits:In Part I of this series, I discussed some of the global trends in freshwater availability and drinkability. It is nothing less than amazing to me that somehow 6 billion people sustain life on the roughly 1% of the earth’s water that is not salt water or brackish water (comprising about 97.5%) or encased in polar and glacial ice (about 1.5%).
An important industry has developed around this fact to treat, clean, and transport this water from its various sources to where people drink it, shower in it, irrigate their fields with it, and use it in literally thousands of manufacturing and agricultural applications. Because of the limited supply, much of this “waste” water is then purified, cleaned, and recycled for use again. But we can only refresh, re-use, and recycle so much.
