According to Dutch scientists at the Wageningen University, Wi-Fi signals are killing trees across the globe. The team of researchers took 20 ash trees and exposed them to various types of radiation including Wi-Fi for a period of three months. At the end of the three months subject trees showed signs of radiation sickness which are the same symptoms shown during the onset of death. One could hypothesize that cities with high internet usage and concentrated Wi-Fi blankets like San Francisco are contributing to the decline of our green friends. As a researcher myself, I conclude the study is bullshit until I see an experiment where trees are only exposed to Wi-Fi and not other forms of radiation.
