The waves emitted by our mobile phones are again pointed out.
According to European NGOs, they could be partly responsible for the disappearance of insects.
All the studies on the subject affirm it: insects are disappearing in a worrying way. According to a German study published in October 2019 in the journal Nature, the biomass of arthropods (a family of animals comprising millions of species, including spiders, insects and crustaceans) has decreased, in ten years, in Europe, 67% in grasslands and 41% in forests.
In question: pesticides, deforestation but not only. Radiation from our cell phones could also be a culprit. This is the conclusion of an analysis, published Thursday, September 17, 2020 by the German NGO for the conservation of nature (NABU), in collaboration with other German and Luxembourg NGOs, after examining 190 studies on the subject.
An impact on the immune system and reproductive capacity
According to this analysis, the radiation of cell phones and wireless networks such as WiFi cause, especially in insects, the opening of calcium channels in cells, causing a significant introduction of calcium ions into the body. This high-dose calcium triggers chain reactions in insects. Among them, "an altered sense of direction and a decrease in reproductive capacity". The authors of the review also cite a "disturbed day-night rhythm and a poorly activated immune system."
Without insects ... no plants and no food for humans
However, the disappearance of insects poses a problem, not only for the species that consume them (birds, amphibians, fish, etc.) but also for plant biodiversity: with the disappearance of pollinators (bees, bumblebees, butterflies) no reproduction of plants, fruits and vegetables. As a reminder, according to Greenpeace, 75% of global food production depends on pollinating insects.
This NABU study is published as France and Europe begin the deployment of 5G, a technology that offers speeds 100 times faster than that of existing 4G networks and which worries many environmental experts.
