According to PCWorld, now it looks like the radiation from Wi-Fi networks is making our trees sick.
According to the study, translated from Dutch using Google Translate, trees in urban areas of the Netherlands showed an increasing number of damage such as cracks, bumps, discoloration and various forms of tissue damage.
The research, by Wageningen University, was commissioned by officials from Alphen aan den Rijn, a city in the western region of the Netherlands. They asked for the research after discovering trees that did not appear healthy. Further, the trees could not be identified as suffering from a virus or bacterial infection.
According to PC World, further study showed that the disease has similarities affecting trees throughout the Western hemisphere.
Trees in urban areas appear most affected. The study found that 70% of all trees in urban areas show the symptoms, compared to 10% five years ago. Trees in dense forests do not appear to be impacted.
Wireless LAN networks and mobile phone networks may be only partly to blame. Ultrafine particle emissions from cars and trucks may also be responsible.
"The study exposed 20 ash trees to various radiation sources for a period of three months. 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."
Researchers say that more studies need to be conducted before any clear conclusions can be made.
