Study finds WiFi makes trees sick; affects all deciduous trees in the Western world

Parallels Desktop 6 for Mac“Radiation from Wi-Fi networks is harmful to trees, causing significant variations in growth, as well as bleeding and fissures in the bark, according to a recent study in the Netherlands,” René Schoemaker reports for Webwereld Netherlands.

“All deciduous trees in the Western world are affected, according to the study by a group of institutions, including the TU Delft University and Wageningen University,” Schoemaker reports. “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.”

Schoemaker reports, “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.”

MacDailyNews Take: Uh, great (as we sit here with WiFi streaming all around and, likely, through us – for the last 11+ years, no less).


  1. Hmm the tree outside my Airport for the last ten years has gained about 4″ in diameter.

    I keep having to prune the damn thing myself so I get some light in my office.

  2. Sure, the radiation might affect tree cells but I trust the Wifi Manufacturers Association’s claims that humans are not affected, and that the recent rise in certain cancers has no relation to the proliferation of wifi. You’d have to be an enviro-wacko to think that.

  3. Checking the calendar….nope, not April 1st…. Is this for real? Somebody set a bonsai on their WAP and see if it turns into an Audrey 2. This just sounds too wonky to be real.

  4. RTFA for the bad science:
    “Trees placed closest to the Wi-Fi radio demonstrated a “lead-like shine” on their leaves that was caused by the dying of the upper and lower epidermis of the leaves. This would eventually result in the death of parts of the leaves. The study also found that Wi-Fi radiation could inhibit the growth of corn cobs.”

    Duh? 2.4Ghz is the same frequency your microwave oven uses to boil water. Don’t stare at or leave your naughty bits next to the microwave when cooking.

    Seriously, they aren’t saying what the power output was, if this was at 2.4 (wireless b/g/n) or 5Ghz (a/n the really good Highspeed stuff). If this study deserves any credit, it should be listing how the effects varied at different ranges, as well as durations.

    All this is telling me is don’t put my airport extreme in my evergreens as a Christmas decoration. That’s some good sciencing right there. (rolls eyes)
