Research shows that trees, plants, pollinators and wildlife are harmed by wireless radiation.  

Fact: ICNIRP and FCC limits were not developed to protect our flora or fauna. Wireless radiation “safety” limits for trees, plants, birds and bees simply do not exist. No US agency with expertise in science, biology or safety has ever acted to review research and set safety limits for birds, bees, trees and wildlife. 

A landmark three part 2021 research review on effects to wildlife published in Reviews on Environmental Health by U.S experts including former U.S. Fish and Wildlife senior biologist Albert Manville states current science should trigger urgent regulatory action citing more than 1,200 scientific references which found adverse biological effects to wildlife from even very low intensities of non ionizing radiation with findings of  impacts to orientation and migration, reproduction, mating, nest, den building and survivorship (Levitt et al., 2021a, Levitt et al., 2021bLevitt et al., 2021c).

The Department of Interior wrote a letter in  2014 detailing several published studies showing impacts of wireless radiofrequency radiation (RFR)  to birds stated that, “There is a growing level of anecdotal evidence linking effects of non-thermal, non-ionizing electromagnetic radiation from communication towers on nesting and roosting wild birds and other wildlife…. And  “However, the electromagnetic radiation standards used by the Federal Communications Commission (FCC) continue to be based on thermal heating, a criterion now nearly 30 years out of date and inapplicable today. “ and “third-party peer-reviewed studies need to be conducted in the U.S. to begin examining the effects from radiation on migratory birds and other trust species.” 

“Study results have documented nest and site abandonment, plumage deterioration, locomotion problems, reduced survivorship, and death (e.g., Balmori 2005, Balmori and Hallberg 2007, and Everaert and Bauwens 2007). Nesting migratory birds and their offspring have apparently been affected by the radiation from cellular phone towers in the 900 and 1800 MHz frequency ranges- 915 MHz is the standard cellular phone frequency used in the United States.”

“In laboratory studies, T. Litovitz (personal communication) and DiCarloet al. (2002) raised concerns about impacts of low-level, non-thermal electromagnetic radiation from the standard 915 MHz cell phone frequency on domestic chicken embryos- with some lethal results (Manville 2009, 2013a). Radiation at extremely low levels (0.0001 the level emitted by the average digital cellular telephone) caused heart attacks and the deaths of some chicken embryos subjected to hypoxic conditions in the laboratory while controls subjected to hypoxia were unaffected (DiCarlo et al. 2002).” –Department of Interior, 2014

Albert Manville, former senior biologist of the US Fish and Wildlife Service  wrote “A BRIEFING MEMORANDUM: What We Know, Can Infer, and Don’t Yet Know about Impacts from Thermal and Non-thermal Non-ionizing Radiation to Birds and Other Wildlife”  published in  Wildlife and Habitat Conservation Solutions, 2014 on the impacts of RFR  to birds and bees. India dropped their RF limits by 1/10th after a research review documented the majority of research studies found adverse effects to wildlife, birds and bees.  

Regarding bees and pollinators, the study “Exposure of Insects to Radio-Frequency Electromagnetic Fields from 2 to 120 GHz” published in Scientific Reports found insects (including the Western honeybee) can absorb the higher frequencies that will be used in the 4G/5G rollout with absorbed power increases up to  370%. The researchers warn, “This could lead to changes in insect behaviour, physiology, and morphology over time….” Research also has found impacts to bees from wireless frequencies including inducing artificial worker piping (Favre, 2011), disrupting navigation abilities ( Kimmel et al., 2007)  reducing colony strength (Harst et al., 2006) and other impacts to honey bee physiology. 

In 2020 Alfonso Balmori reviewed research that has been conducted on the link between exposure to power-frequency fields and wireless radiation and the decline of insect species in a paper entitled  Electromagnetic radiation as an emerging driver factor for the decline of insects.” He found some of the harmful effects on bees from power-frequency and wireless electromagnetic field  sources  include:

  • loss of queen cells
  • changes to weight gain of hive
  • poor survival in winter
  • changes to propolisation
  • changes to flight, foraging and feeding
  • changes to short-term memory
  • causes worker piping signals which can mean disturbance or preparation for swarming
  • reduced egg-laying speed of queen
  • no honey or pollen in a colony by the end of exposure
  • lower weight of honeycomb
  • increased mortality.

 

Balmori 2020 concludes, “here is sufficient evidence on the damage caused by electromagnetic radiation. The precautionary principle should be applied before any new deployment (e.g. 5G).”

 

Research on trees has found trees are harmed by RFR. A 9 year field study Waldmann-Selsam, C., et al 2016,  found significant impacts to trees near cell antennas and an investigation of 700 trees found damage starts on the side of the tree with highest RF.

A review on impacts to plants entitled “Weak radiofrequency radiation exposure from mobile phone radiation on plants concluded, “a substantial amount of the studies on RF-EMFs from mobile phones show physiological and/or morphological effects.”

A study on aspen seedings found ambient RF in a  Colorado setting were high enough to cause necrotic lesions on the leaves, decrease leader length and leaf area, and suppress fall anthocyanin production (Haggarty 2010).

Several literature reviews warn that non ionizing EMFs are an “emerging threat” to wildlife (Balmori 2015, Curachi 2013) .

Examples of Research Studies on Effects to Wildlife 

 

The European Scientific Committee on Health, Environmental and Emerging Risks states “The lack of clear evidence to inform the development of exposure guidelines to 5G technology leaves open the possibility of unintended biological consequences.” Several literature reviews warn that non-ionizing EMFs are an “emerging threat” to wildlife (Balmori 2015, Curachi 2013, Sivani 2012) .
