Tree hugging hippies
I saw a T-shirt about 5 years ago a guy in a band was wearing, it said:
"The Hippies were right"
Indeed, I remember a time back before many people were concerned with things like global warming, organic foods, and environmental sustainability that most people were laughing at the hippies as mostly nutjobs.
Even if you don't believe they were right they were certainly closer to correct than most people gave them credit for.
It is likely due to other things (maybe even better detection) but I think cancer rates are generally rising. Low power wireless communication might be harmless but there is no reason not to limit exposure where we can.
