Biodiversity, the disappearance of insects

Humanitarian catastrophes (including resource wars and conflicts), natural, climate and industrial (except nuclear or oil forum fossil and nuclear energy). Pollution of the sea and oceans.

Really?

You obviously did not read or did not want to understand my message above on the blue light that disturbs the sleep of men ...

Disrupting psychologically is not a direct danger in itself ... but it can have great consequences indirectly ...

So how can you say with so much confidence that mobile phone waves do not disturb insects ???

For blue light, it is still a question of dose and specific situations.
You didn't mention a link, here is one from Serge Picaud research director at the Vision Institute, INSERM research center, CNRS and Sorbonne Universités (UPMC). Little apologies. : Mrgreen:

I had heard it on FC https://www.franceculture.fr/emissions/ ... embre-2018


On the other hand, the led light from the garden will exhaust the moth, which may not have the strength to lay its eggs.

The problem of biodiversity islands that are fallow lands waiting to be sold as building land is dramatic for a large part of the living whose range does not allow to colonize other islands. Especially the part that lives underground.
To make pellets, we make clear cuts ... hello damage.

and to top it off, the pesticides he will have absorbed that will have made the eggs sterile.

Yes, well, that's shit!

And then I wonder if finally the disappearance of bees that we have been talking about so much for over 15 years ... does it not simply enter into this context of global disappearance of insects?

I mean: there would be nothing specific to bees ... except that bees, this is certainly seen faster ... since they work directly for humans ...

Personally, I find the sun's rays aggressive, we did not have UV alerts to the weather reports a few decades ago ...

Domestic workers should be better managed because they compete with wild pollinators, which are much more at risk http://www.inra.fr/Chercheurs-etudiants ... omestiques.

The facts contradict your impression : Wink:
Today, a report by experts mandated by the United Nations is particularly optimistic. Since 2000, the ozone layer has been replenishing at a rate of 1 to 3% per decade. https://www.futura-sciences.com/planete ... ent-63386/
True gaseous shield located between 20 and 50 km above the ground, the ozone layer protects us from solar radiation by absorbing ultraviolet ... avoiding skin cancer, eye problems, and other immune damage. The image of the “hole” ripping it over Antarctica haunted the years 1980/1990; but since the 2000s, this has reduced by 4 million km² following the adoption of the Montreal Protocol in 1987, several times amended, which allowed the ban on chlorofluorocarbons, the main culprits of the disaster. https://www.franceculture.fr/ecologie-e ... che-dozone

For them to contradict they should be based on a minimum of physics ... and scientific logic!

The impression of heat is infrared (IR), nothing to do with Ultraviolet (UV) and therefore nothing to do with the ozone layer !!

Is it hot in a UV tanning booth? Apart from the heat losses from the tubes, this does not heat up! And fortunately!

Replace the UV tubes with IR electrical resistors (toaster type) and users will burn after a few minutes ...with the same installed electrical power (I think a cabin is between 2000 and 3000W electric *)

UV rays therefore have nothing to do with the aggressiveness felt by the sun: UV rays (at least in "terrestrial and natural" doses make the skin tan but do not burn it and they do not make you sweat either: but when you are in the sun you cannot receive UV rays without having IR)!

In short on the impression of heat from the sun, the facts are these:



* information taken is more than 3000W (but nothing is too good for your cancer !!):

UV power

Body tanning: 38 UV tubes 160 W = 38 * 160 = 6400W
Face tanning: 3 UV High Pressure lamps 360 W = 1100 W

Shoulder tan: by reflector system

Ergoline Advantage 350 Solarium

If you are new to UV tanning in the cabin, then the Ergoline Advantage 350 solarium is ideal.
It offers a gentle tan with basic comfort for a simple and pleasant UV tanning session.
The minimum comfort options such as ventilation and sound volume adjustment allow you to discover tanning with pleasure and serenity.

To return to biodiversity I found this diagram sympathetic! Insects are among the first victims of the lack of bushes:

I had thought aggressiveness in the insidious sense, not direct as with the heat or our senses signal us by the pain that we must protect ourselves ...
Exposure to UV radiation is a cause of skin cancer, whether exposure is to the sun or in a tanning booth, some countries have banned these booths. https://www.pseudo-sciences.org/spip.php?article2620
and also Tanning booths: an increased risk of confirmed cancer
