Five years ago the Dutch city of Alphen aan den Rijn commissioned a study to find out why the trees in their city were developing weird abnormalities. The study was headed by a researcher from Wageningen University and yielded some very interesting findings. It found that 70% of trees in cities exhibited the same symptoms while only 10% did five years ago. The reason, the study suggests, is due to Wi-Fi. The radiation from the rise of airborne Internet signals in cities seems to be negatively affecting the trees.
