Research conducted by Wageningen University in Holland has come to the disturbing conclusion that electromagnetic radiation emitted by Wi-Fi access points and mobile phones could be killing trees.
The research was commissioned by the city of Alphen aan den Rijn, following the discovery of abnormalities on trees that experts believed hadn't been caused by regular viral or bacterial infections.
It appears that trees in urban areas have been showing an increasing amount of damage such as cracks, bumps, discolouration and various forms of tissue necrosis.
And the research conducted by the University suggests that the damage is being caused by radiation from Wi-Fi access points and mobile phones.
The trees were exposed for more than three months to six sources of radiation with frequencies ranging from 2412 to 2472 MHz and a power of 100 mW EIRP at 50cm distance.
After a few months a metallic lustre appeared on leaves that appeared to be the result of the disappearance of the outer cell layer of the leaves. The discolouration was followed by desiccation and death of a portion of the leaf.
The researchers say their initial findings suggest that all western deciduous trees are affected by the disease. Other plants are also likely to be affected.
The researchers urged a repeat of the tests, preferably for a longer period and on a larger scale.
