Hello @whatisnew,
Thank you very, very much. Your point about drinking purified water is so apt. How do we get around this? It seems we need the kind of dedicated research we put into developing nuclear power plants and missile systems. But the will to protect our water does not exist, at least not on that level.

I am working on a new project...so hard when it starts, but so engrossing. Right now I'm supposed to be sorting laundry--my husband is doing his bit, but I keep coming back to the computer to look up elusive information:))

Looking forward to your lovely and informative nature blogs.

Hugs,
AG
