Parents’ advocacy groups in Canada and the US are successfully getting schools to ban wireless internet access due to health concerns.
It seems as though there have been more of these stories over the last year or so.
Although I think that keeping phones out of the classroom is a good idea (you are there to learn, not text, right?), is banning wifi in public places based on evidence or unjustified fear?
Points from the story:
- In May of 2011 the World Health Organization classified the RF signals sent via cell phones and wifi connections as “possibly carcinogenic”
- Health Canada states that there is “strong evidence” that current exposure levels to wifi signals are not dangerous and no additional precautions are necessary
- Some parents believe that their children have experienced headaches, nausea and heart problems due to exposure to wifi signals
- Magda Havas, a Trent University professor argues that there is research showing that exposure to radio frequencies leads to an increase in tumors for rats
- Dave Michelson, an electrical engineering professor at the University of British Columbia believes that wireless internet is safe and that groups trying to enforce bans are doing more harm than good
What do you think? Is our precious wifi access slowly killing us (get in line wifi, you have a lot of competition), or is this just a “sky is falling” overreaction with not enough evidence to back it up?

As social media becomes more and more intertwined with our lives, problems like online bullying, internet, and video game addiction will almost certainly become more common.
It’s not all negative though. Case in point: Facebook announced a program today that may be helpful for people experiencing suicidal thoughts.
Here’s how it works:
If you see one of your friends expressing suicidal thoughts or intentions, you will be able to click a link next to the comment. Facebook then sends a link to the user with the opportunity to instantly connect (online chat or on the phone) with a crisis counsellor from the National Suicide Prevention Lifeline.
Good idea I guess. Do you think there is a possibility it will be abused though (e.g., pranks)?
