Bill,
I don't think there will be enough fresh water for everyone in 50 years. I read on some news report that there are areas around Phoenix that are starting to sink because they have pumped so much water out of the ground that the aquifers can't fill back up via normal ground water. I believe the airport was on of the sinking areas.
Also just two days ago on TV They had a 2 hour show about a desalinization plant that they have built back East but I forget where. It produces quitem a bit of fresh water but they said it was to expensive to build them. I wonder when the easily available fresh water is gone, if it will be any cheaper then.
