A Dutch study claims radiation from WiFi networks is harmful to trees, the scientists believe the electromagnetic fields may be causing significant variations in growth, as well as bleeding and fissures in the bark.
All deciduous trees in the Western world are affected, according to the study by Wageningen University. The city of Alphen aan den Rijn ordered the study five years ago after officials found unexplained abnormalities on trees that couldn't be ascribed to a virus or bacterial infection.
Additional testing found the disease to occur throughout the Western world. In the Netherlands, about 70 percent of all trees in urban areas show the same symptoms, compared with only 10 percent five years ago. Trees in densely forested areas are hardly affected.
