A related anecdote. 15 years ago, an investment advisor was pitching us on investing in water funds. Yes, the move to privatize water was well underway a quarter decade ago because the people with money KNEW we would have a world where rivers in multiple continents running out of water in the future.

That it's come sooner than most predicted is likely making those ghouls salivate even more.

Needless to say, we turned him down and just plunked our money into index and sustainable funds and chose handpicked stocks instead.
