David, I read about every one of the comments at the end of the Guardian report. Emotions run rampant from the fluoridation (fluoride added to our water contains lead as most comes from lead smelters and other chemical industries, one person called it waste management, which is true) to old pipes, the govt, the corporations etc etc etc. In many ways we are doomed, so have to do our best to KNOW as much as we can and take best action that we can. Heads in the sand are just that.
