One of the problems unique to the 21st century has involved the clammoring over potential health-risks posed by WiFi signals. Parents in a New Zealand have decided to take things into their own hands to protect their kids from these risks.
“Two parents in New Zealand have orchestrated the removal of a school’s Wi-Fi system. They have expressed the concerns that Wi-Fi causes cancer and other health issues. The child of one of these parents died recently from brain cancer. This appears to be an emotional area and one where decisions appear to be being made without evidence. The NZ Ministry of Education provides guidelines for the safe use of Wi-Fi in schools and the school itself was operating within those guidelines.”
