We have plenty of studies already showing biological damage from 2,3,4G systems. Now they want to roll out a completely new frequency band on top of the current system, without any sort of health or safety testing. No testing whatsoever.

Now those scientists which have looked at 5G have noted things like our sweat ducts in our skin act like waveguides for these shorter wavelength frequencies, with potential to steer the radiation into our nervous system. This is just from one independent study that looked at what potential harm 5G could have. Additionally it is suspected that there may be synergistic effects with the currently deployed 2-4G systems.

In summary; there is a limit to how much radiation we and the environment can take. We already know from current studies microwaves are harmful, and now they're planning to double down on it with complete disregard to warnings from independent researchers.
