In each case the people who showed early concern were labeled alarmist.
If you pick and choose your examples you are not going to reach a logical conclusion. The basic principle when you introduce a new chemical to the environment or a new exposure burden to humans should be precautionary
Absence of evidence is not evidence of absence.
Do you drive into the night with your headlights off? Why not?
We are driving into the night of chronic microwave exposure. All studies showing no harm are short-term (a decade or less), when we know that cancer is often a 20 to 30 year disease. Some disturbing trends are just now starting to crop up. It's early days, perhaps they are not that significant.
We don't know, but ignorance is a very poor argument in favor of anything.
I seem to recall the biggest fuss in the US about removing lead in gasoline was more a matter of timing. It had to go first and foremost because it would poison the catalytic converters but engine manufacturers had to scramble to figure a reliable redesign to compensate for the removed lead. And what kind of substitute could you use on older existing engines.
Asbestos was bad and figured to be bad pretty quickly. In some products, however, the replacement was made dangerous in other ways. As a matter of fact I argue that the hysteria over asbestos has had some very negative effects and caused some people and regulatory agency's to do some very stupid things. Early on many people removed it themselves or had people remove asbestos insulation improperly and exposing themselves to far more then had they let it lay. As a matter of fact if its not crumbling or disintegrating often times it is actually better to leave it. Especially if it is not going to be disturbed you can leave it or cover over it. As an example you can cover over asbestos sheeting with new insulation and siding and will save money by not removing it and help the environment by not releasing those microfibers into the environment and exposing countless people to them.
Dupont who jumped on the cfc bandwagon very early on was a big supporter about removing Freon (R-12 and r-24) from the market. What we in the heating and cooling business found funny and a bit suspicious was that there patents on Freon were expiring and that they had new refrigerant ready to go but needed a reason for people to switch. See at the time the new refrigerants were considered slightly more environmentally friendly but were far more inefficient (25-35 percent) and manufactures were reluctant to use them because they required new designs and the development of new material for hoses and such that the knew stuff would not destroy.
I don't think any of those things compare to the scare of the cellphone radiation. As others have pointed out you are constantly bombarded by radio waves and radiation from your monitor and Electromagnetic fields from a multitude of sources. I would also point out all those people in the 50's and 60's that sat right in front of those old tubed tv's that put out a lot of radiation. Somehow they managed to survive countless hours of exposure from those old radiation kings.
But using a little common sense regarding cellphones and cordless phones would probably be a smart thing. I think that is notion many people should apply in there lives. Eating at McDonalds occasionally is OK eating three meals a day there not so much. Etc, etc I think you get the idea.
I have been using a cellphone on a daily basis since 1989. I had to it was required as part of my job. The first phone I used was this big bag phone that had a full three watts of power versus .5 watt most handhelds output now. If using a cellphone causes tumors or cancers then unfortunately I will be finding out soon.
I also wonder if using a laptop in my lap for so many years helped to contribute to son's autisism. Has anyone measured how much radiation a laptop puts out?
Just some thoughts.
