What are the natural background levels of RF vs. sunlight from an evolutionary perspective? Consider whether organisms would spend energy evolving protections against a dominant spectrum of wavelengths vs. hardly measurable spectrum. Also, consider that the net resulting incidence voltage from unpolarised sunlight amounts to near zero, whereas man-made RF is polarized.
