One of the most tragic events in the history of education is the introduction of wi fi in the public schools. The W.H.O. has designated the pulsed radio frequency microwave radiation from wi fi routers to be a "Group 2B Carcinogen." Our educational system has been quietly privatized to Cisco systems and the Military through the S.T.E.M. programs. The schools train our kids to work in the tech industries with our tax money, while irradiating our kids at the same time. The curriculum is being drawn up so that it requires Cisco hardware and software. It is a dangerous closed loop system. There has not been one study that has shown that this technology helps the learning process however there have been a number of studies (on my website) that show cognitive effects as well as biological effects. The truth of all this is that there is no safe threshold for exposure and Cisco and the military, who has done thousands of studies on this type of radiation, know and have known that these frequencies are some of the worst for human exposure and especially for children. We are running blind into this. I guess the correct term is that we have been overrun by this technology with no premarket safety testing. Our children may be sterilized, get cancer, become stupid (digital dementia) and certainly trained to become unfocused. It remains to be seen what will happen to our kids but it looks pretty grim from this vantage point with 7 years of research behind me.
