So take your pick on what to "believe". I can take an educated guess on their effects. We may not see them for years to come.
Same as lung cancer and cigarettes.

It sure is strange why the goverment had to put "emf" output level caps on cell phones, and why certain types have been put out of production because they didnt meet these reqs. After all they are perfectly safe.

I also live in town with paper mill that "doesn't" cause one of the highest rates of allergies/sinus problems in the country, or the highest rate of hodgkins disease ( a form of lymph cancer) in the country. And it doesnt smell bad enough to keep other commerce from entering our area. The mill is a gold mine and I wouldn't want anything to happen to it or the jobs of some of my friends. Who cares whether they discharge hot effluent directly into the water or whether their settling ponds are visably leaching scudge thru the banks into the river.
It's no forseeable damage. We'll just look the other way, and see things the way that meet our needs.
