Bill, do you have time for giving a crash course in chemistry? I understand that copper is a required trace "mineral", to ensure the proper biological function of many organisms, but at what point does copper become toxic to humans? I am not being a naysayer here by any means, I SWEAR!! I know in sheep, you never feed anything with copper, but with cattle and goats, a little is a good thing. help me understand? And then you read "reports" and copper plumbing is not good for you, and modern PVC contains estrogen mimicking compounds,but drinking out of the ditch aint much good either.....any off the record, non-liable opinions? The whole metals thing has me confused?
