Thank you for posting this. All these modern gadgets we use have only three possibilities: they are biologically good for us, biologically neutral, or biologically harmful. There are no other alternatives. The history of such post industrial-revolution mechanical devices, esp. electronic ones, have consistently been shown to be harmful to the natural elements of the world, including our persons. All one need do is think of the internal combustion engine. Who will give up this way we are all used to of getting around?
The cell phone industry, is indeed, as the vid points out, acting in the pattern of the tobacco industry's earlier history. However, the fact that so many people have become dependent on them, THAT THEY ARE SO CONVENIENT, and that we have become so used to that convenience, will make it very hard for most people to even consider giving them up or cutting back on their use---until disaster strikes and the user develops cancer, even as the victims in this video indicate. One is reminded of Al Gore's "An Inconvenient Truth" here.
A court case in Italy last year reversed the trend in western lands of governments rejecting the scientific studies done by Scandanavian researchers into the harm of cell phone usage. Of course the Scandanavians have always been more attuned to safety than other western cultures.

As with polluting the earth with our transportation system, we are nearly all guilty here. Your suggestions are wise (except maybe that speakerphone which would destroy the privacy we wish when talking!). One more help: since the cell phone is continuously emitting radiation when on, even when we're not talking on it (because it is always seeking out the nearest tower), to stop the radiation completely, we need to turn it completely off when not using it.
