Nature is about balance. Faced with millions of different species present on earth, the behavior of a single threat all: man. With its association, Hugues Mouret seeks to raise awareness and initiate a return to basic common sense, with respect for ecosystems and in particular insects. He explains it in “You are amazing” on France 3 Auvergne Rhône Alpes.
” Getting to know insects and respecting biodiversity »Is the purpose of the association« Arthropologia », whose naturalist Hugues Mouret is the scientific leader. In short, it relies on scientific facts to demonstrate how man would saw off the branch on which he is sitting.
His garden is located in Saint-Pierre-la-Palud (Rhône), where there is also an old mine and a museum dedicated to him. A garden that has developed a lot. ” I left the time and place of nature to perform a work that it does much more efficiently than us , ”Comments this enthusiast. ” In 10 years, the trees have exceeded the height of the house. As long as we let nature express itself under the right conditions, we get very interesting benefits from it. There is no longer sun on the house, which formerly, oriented to the south, was a real stove. And the garden produces quite a lot today. »
The passion for the protection of nature, he embraced it from an early age. ” I grew up at the foot of La Dombe, not far from Ars-sur-Formans and Sainte-Euphémie. I bathed in nature as much as possible. I spent as much time as I could watching the little animals, the plants … the insects eating, foraging … “, He sums up. ” Today it is both my hobby and my job. And probably also a form of priesthood. »
Hugues is self-taught. Over the years, he nurtured this passion on his own by studying the environment until he formed an association. Lyon’s eco-center “Arthropologia” has been located since 2001 at the Tour de Salvagny. ” We are located in a former organic garden plot, spread over two hectares. They have been partially returned to nature. We planted 2,200 trees, dug three ponds, installed theme gardens, with conservation plants … It’s a really wild garden “Describes our interlocutor.
The association wants to be a naturalistic association, which campaigns for the protection of nature and change of practice by implementing concrete measures in favor of biodiversity, especially insects (excipients, pollinators, decomposers), plants and their habitats. ” These are elements that are stacked and depend on each other. »
We can make up for what we have destroyed. But never up to what is gone
The idea of highlighting insects is original. ” Twenty years ago, almost no one cared. This is one of the paths we have opened up by trying to raise awareness, conduct research, support farmers and change the vision of our community and community. »
Its members intervene in various ways. “ We arrange animations, discovery nature excursions around themes. We also offer conferences for the general public. It can also be vocational training, in a slightly more institutional setting, with farmers and green areas. It is also a matter of taking into account the respect for what already exists. ” We can make up for what we have destroyed. But never up to what has disappeared. So the priority is still to keep what is functional, starting with the big trees. »
Arthropologia fights for biological diversity. “ When we talk about the living, we think for the most part of small flowers, birds, fungi or organisms. But the reality is more complex. ” Upstream, we have genetic diversity, which is the engine of evolution. It’s inside their cells, in the heredity of these organisms, so we do not see it. “Without forgetting other levels:” The diversity of ecosystems, and the cycles of water, carbon … In short, everything that makes organisms function, under the influence of their genes, in the ecosystem. They are called ecosystem services.»
Very quickly we are approaching scientific topics that may seem more abstract. ” But it is important to insist on these notions, because the collapse of biodiversity is not just the disappearance of birds and plants. It is rather the end of nature’s ability to adapt, and of all the above systems » announces our enthusiast.
Clearly threatened, can biodiversity be quantified? “ We know about 2.4 million living species on the entire planet, while there are probably 10 times more … If we come back to France, there are 43 amphibians, 38 reptiles, 156 mammals, 578 bird species he enumerates in his head, concerning vertebrates. ” Next to them we have 1,000 species of bees, 6,500 flies, 5,600 butterflies, 11,000 beetles … it abounds with life. This represents 100,000 species of life in France he adds.
When it comes to agriculture, no less than 75% of our food is dependent on these insects
And … a single human species, one and the same on the entire planet. This unique species harms biodiversity. ” Of the millions of known species, more than half are insects. We measure a level of disappearance 1000 times higher than normal. It is estimated that approximately 26,000 species disappear from the planet each year. But it’s probably a lot more. »
Which is not unusual. Insects play a vital role in our system. ” Take the example of bees. There are 1000 different species. Small, big, yellow, black, hairy … We have tamed one species, in the hives … but in reality it is all these 1000 species that will ensure the pollination of the plants. 9 out of 10 plants are pollinated by insects. When it comes to agriculture, no less than 75% of our food is dependent on these insects », Explains Hugues Mouret.
The danger, according to our expert, is unique: human action. “ For nature, it is about balance. The causes of the collapse of biodiversity are known. First, it is pollution, then the destruction of habitats and behind the climatic fire. Global warming is a consequence of the first two plagues. ” And if we want to fight this climate fire, we will have to tackle the reinstallation of biodiversity. Because it’s thanks to it that we have shadow, evapotranspiration or even the natural cessation of pandemics. »
we have movements that are quite simple to do. Especially leaving a place for nature wherever you can
To organize this return, the solutions are different. ” We must start by reducing energy waste. We are not talking about light pollution due to night lighting. It is a major cause of insect extinction because the majority live at night , ”Hughes suggests. ” More generally, we have movements that are quite simple to perform. Especially by leaving a place for nature wherever you can: in a private garden, on the sides of the road, in public parks, campuses, hospitals, barracks … There are thousands of acres that are managed in the traditional way when it could serve as life support, sustenance. And especially trees, which produce organic matter. It is large. When it falls and penetrates the earth, it becomes the largest carbon drain in the continental biosphere, apart from the ocean. »
With regard to agriculture, our expert condemns the technique of land consolidation, which continues. Hedges are destroyed to create large agricultural areas. ” It’s a real disaster. It is associated with this commodity of the living. We want bigger and bigger tractors, which are especially hampered by these hedges, the ramparts. In 100 years, we have mowed nearly 2 million kilometers of hedges, or 50 times around the earth.»
These are the richest biotopes, in temperate zones. And yet we have already drained 70% of it!
Wetlands, however, are not insignificant in the overall balance. ” These are the richest biotopes, in temperate zones. And yet we have already drained 70% of it! These lakes, ponds or meadows play a fundamental role. In fact, far from the negative image attributed to them due to the presence of mosquitoes … ” In these wetlands, there are enough predators to drive mosquitoes away. In a living pond, there are usually very few mosquitoes that appear. The reason for their spread is rather linked to our lifestyle. It’s the water recycling cans, the poorly unblocked canals, the cups under the plastic flowers, filled with water in the cemeteries … This is where the mosquitoes’ cycles take place without any predators intervening. The heat does the rest …“, Corrects our interlocutor.

Hugues Mouret answers the very shabby question

A good opportunity to advise, to begin with, each one with their own garden to dig a pond. ” This will pick up the mosquitoes and a whole bunch of insects will come out to chase them away. Contrary to popular belief, it is a protection against these mosquitoes! »
