We provided a PSA and here is the postcript:
My third "ask me anything" on Reddit was the most popular so far. There were 2,700+ comments (300+ from me) on a range of topics. Many were directed at silver bullet solutions ("reduce demand through vegetarianism!" or "increase supply with desalination!"), many were "what can I do?" or "how screwed are we?", and a good number came from people wanted to work on water issues. About 20-30 percent were about water issues in other countries (India, Saudi, Brazil, Mexico, et al.)
As usual, it was a fun but exhausting 6-7 hours of give and take.
I am VERY happy that an AMA-bot has collected and formatted the popular questions and my answers, but these were my favorites ...
These are only a few, but there are many more as well as the FAQ-type links I provided at the top of the AMA. (Luckily, it looks like people downloaded around 1,000 copies of Living with Water Scarcity. Free is a good price :)
I'll add here a few things that I should have on the AMA, i.e., a primer on water in California from the Legislative Analyst's Office (source of the figures) and statistics on urban water consumption [my XLXS from here] that show the highest users (above state median of 100 gallons/capita/day -- four times the use of people in Amsterdam) are mostly in southern California. Lawns anyone?
