Anti-cell phone and anti-wireless groups and movements are starting to take hold in many cities.  These people will probably be considered visionaries of the same sort as people who knew long ago that smoking is medically harmful.  But emitting radiation is worse, because it affects those of us who don't use cell phones, including all non-humans.  In order to function, a cell phone or wireless system has antennas that emit radiation to which we are all exposed.

If people want to expose themselves to non-ionizing radiation in the hope that it won't cause any ill effects at less than thermal levels, that's their business.  But the rest of the planet should not have to be exposed to this pollution.  I agree with Umbra that cell phones are annoying as hell, but I'm even more concerned that we're nuking the planet with radiation (the non-radioactive type).
