Ahmed wrote:Among the explanatory factors for the gradual disappearance of insect populations, we must cite light pollution: these little animals did not have time to adapt to the night lighting which made them circle around the lampposts until 'to exhaustion (they are "configured" to locate in the sun). The bats had spotted the merry-go-round ...


Except that it is 200 years that night lighting is used ... and the phenomenon of insect genocide seems much more recent (20 or 30 last years ...).

Okay, there is more and more light pollution ... But the countryside is still spared on the vast majority of their territory!

In short, I believe much more in the responsibility of EM waves ... which are everywhere and increase at speed V!

No scientific evidence corroborates that ... Ah, if :!: , light is one : Mrgreen:

They did not notice any danger since they worked on virtual insects and all the conclusions are conditional. We feel an attempt to oppose the 5G behind all that. : Mrgreen:

If that doesn't work, you can search with the title of the article: "Exposure of Insects to Radio-Frequency Electromagnetic Fields from 2 to 120 GHz" (March 2018).

Insects are disturbed by electromagnetic waves.


Well here I think we have a part of serious explanation on the disappearance of insects (more than pares breeze that are only the consequence!) ... Someone gives us a summary? : Cheesy:

I doubt that a mass media talks about this explanation (no word on EM waves on FranceCulture during the interview of 7 min a researcher at the CNRS, it's crazy anyway !!! In a few hours on econology is done better than a FranceCulture interview and maybe years of research at the CNRS ... I'm sorry!) ... : Mrgreen: : Mrgreen: : Mrgreen:

Yes, there is (again) far too much interest at stake : Evil:


The only thing that is said of interesting in the conclusion is:
This could lead to changes in insect behavior, physiology, and morphology over time in body temperature, from dielectric heating.

Cad that the insect warms up a little because of the electromagnetic wave absorption.

For this it would take a power of the order of the microwave oven, close to the antenna, which is not the case with the power used in radiocommunication. And again, that of the microwave is directional ... Must be in the concentrated beam and moreover, the frequency is chosen for its maximum action on water molecules.
More precisely :
Insects have a maximum of power absorbed by radio frequency at wavelengths comparable to the size of their body. They show a general increase in radio frequency power absorbed above 6 GHz (up to frequencies where wavelengths are comparable to body size), indicating that if power densities do not decrease, but if one passes (in part) at higher frequencies, absorption in the insects studied will also increase. An offset of 10% of the incident power density to frequencies greater than 6 GHz would result in an increase in the power input between 3 and 370%. This could lead to changes in insect behavior, physiology and morphology over time due to increased body temperature due to dielectric heating. Studied insects smaller than 1 cm have an absorption peak at frequencies above 6 GHz, which are not often used for telecommunications, but should be used in the next generation of wireless telecommunication systems.
"With if we would bottle Paris" as my mother often said. I remind you that they did their study on insects reconstituted in 3 D and are counting on subsequent studies for real tests ... Notice to patrons. : Mrgreen:
We look for the little beast, while we have before our eyes the real big beast that destroys its environment. 8)

Yeah yeah ... do not you (a little) tired of almost always defend profit (multinationals) instead of life? : Shock: : Shock: : Shock:

The same info version France Inter: https://www.franceinter.fr/sciences/les ... e-le-pense but still no clear explanation on the acceleration these 20 last years (the pesticides were more dangerous, because more dosed and less controlled, in the years 60-70 ... I do not agree with this, alone , explanation!)

The insects disappear, and it's more serious than we think

This is the result of several studies combined that announce the extinction of insects within a few decades. A real disaster announced for all biodiversity.

According to the authors of this synthesis of 73 studies published in the journal Biological Conservation, we are even witnessing "the most massive episode of extinction" since the disappearance of the dinosaurs. Today, about a third of insect species are threatened with extinction "and every year about 1% more is added to the list", calculated Francisco Sanchez-Bayo and Kris Wyckhuys, of the universities of Sydney and Queensland. . Clearly, "in 50 years there will only be half of it and in 100 years there will be no more."

Insects, unloved but necessary

Small animals, which make up two-thirds of land species, are disappearing at a rapid rate. "The proportion of declining insect species (41%) is twice as high as that of vertebrates," say the researchers. It is certain, one is more easily moved by the plight of large animals than winged critters or with hairy legs that sting and scratch. And yet, they are "of vital importance for planetary ecosystems", insist the scientists who expect a real disaster.

Nearly half of insect species, essential to ecosystems and economies alike, are in rapid decline worldwide, warns study warns of "catastrophic collapse" of natural environments http://u.afp.com/J3GF by @CathHours #AFP

Among the most affected are butterflies and moths of the Lepidoptera family, bees, wasps, ants and hornets, hymenoptera ... Beetles, and ladybugs are also among the most endangered, as well as as pearls, also called stone flies. Aquatic insects such as dragonflies are not spared.

One could rejoice not to have to clean his windshield on the country roads, or to eat more quietly outside, without fearing a voracious attack of bees. But with the collapse of insects, all the biodiversity is threatened. If a buzz will certainly not fail us, what about the song of birds? According to a late 2017 study based on catches made in Germany, Europe would have lost about 76% of its insects in less than 30 years, helping to remove more than 400 million birds. Birds, but also hedgehogs, lizards, amphibians (like frogs), fish ... all feed on insects. In addition, plants are directly threatened by the disappearance of pollinating insects that facilitate their reproduction. But according to Greenpeace, 75% of global food production depends on these bees and other drones.

Intensive agriculture pointed the finger

The decline of insects dates back to the beginning of the 1950th century, but it accelerated in the years 60-20 to reach "alarming proportions" during the last XNUMX years. Urbanization, deforestation, agricultural conversion ... Insects are losing their habitat, driven out by the intensification of agricultural practices, and especially the massive use of pesticides and synthetic fertilizers. Sánchez-Bayo points in particular to new classes of insecticides, such as neonicotinoids, banned in France since 2018 (except derogations), and fipronil which persist in the environment: "They sterilize the soil, killing all the worms", he explains. To this are added pathogens (viruses, parasites), to which certain species would become less resistant, invasive species and climate change, especially in tropical regions for the moment.

Despite a certain optimism displayed in the face of the disappearance of insects, the vice-president of the French Committee of the International Union for the Conservation of Nature (IUCN) thinks that "we must change gear as quickly as possible". "I do not know if, under these conditions, we can rejoice in the pragmatism of the President of the Republic on glyphosate", notes François Letourneux on France Info. "Because the disappearance of insects is obviously pesticides, insecticides and also herbicides that destroy the environments in which they live."

We should stop limiting the electromagnetic risk to the sole thermal effect !! There is a cellular / neurological effect too !! If a bee can perceive the waves of the kind Wifi or GSM how do you want it not to be disturbed? Nothing to do with a thermal effect so!

For men: why northern countries have much higher standards than in the South ??

Belgium had published a very well done guide: https://www.econologie.com/telechargeme ... mes-sante/
Never seen equivalent (as well done) in France, lobbies are certainly less powerful in small countries! Ah ah ah! : Mrgreen:

The reality is much more complicated than that
and especially the massive use of pesticides and synthetic fertilizers.
is completely wrong and paradoxical. The eco-terrorists have done everything to ban GMOs in our so-called civilized countries ... and yet it is an effective way to reduce the most harmful pesticides that are insecticides. In Bangladessh it saves lives.

The decline in biodiversity in France is mainly due to successive consolidation, which has removed hedgerows and corridors, then the reduction of livestock and grasslands. There is also excessive mechanization. Systematic falconry leaving only room for insect survival. The urban lighting cited by Ahmed is no stranger either.

A slightly more realistic article https://www.echosciences-hauts-de-franc ... ironnement

Thermal effects at frequencies below UV. Above, we enter the ionizing radiation, otherwise more deleterious.
If you can not understand that ... : Cry:

I understand I think ... I'm talking about the effects of EM waves on the living ...

Example: it has been shown that the blue light of LEDs and especially screens tend to excite the brain (or even damage fragile retinas ...)

Is it a thermal effect? No...
Is it an ionizing effect? No...
Is it a neurological effect? Yes...


ps: ok for land consolidation but this does not explain the acceleration of 20 last years since the bulk of land consolidation was done during the mechanization of agriculture so well before the year 2000 ....
