Radiation from Wi-Fi signals may be causing abnormal growth in trees, according to a recent study from the Netherlands. Research suggests that the Wi-Fi radio waves are causing significant variations in growth, leaf decay, and bleeding and fissures in bark.
Researchers bombarded a small sample of ash trees with various radiation sources for three months. Those closest to Wi-Fi emitters developed a "lead-like shine" on their leaves, which eventually caused the epidermis of the leaves to die.
The study was initiated after 70% of urban trees in the Netherlands were found with identical symptoms, none of which could be attributed to a viral or bacterial infection. Trees in forested areas were generally unaffected.
