Abstract
Biodiversity is known as the diversity of the different levels of organization of living organisms (genetic diversity, species diversity, ecosystem diversity), but it is also characterized by the diversity of interactions between living beings : competition, cooperation, predation, mutualism... These interactions, sometimes very close, are the product of a long process of co-evolution, linking the entire surface of the Earth and making biodiversity the " living fabric of the planet ", which regulates its functioning. The current biodiversity crisis, often described by the disappearance of species or changes in population abundance, also implies changes that are harder to observe, but with consequences that are at least as significant : the disappearance of interactions.The planet's fabric is becoming distended, and the interactions between flowering plants and pollinators, which depend on each other for reproduction and food, are a good illustration of this. A solution to reverse this trend may lie in re-establishing another form of interaction : those between humans and the rest of living things, which are also gradually disappearing, not least as a result of our increasingly urban lifestyles.
