Desc: Insecticide, comment l'agrochimie a tué les insectes: Directed by Miyuki Droz Aramaki, Sylvain Lepetit. With Barbara Berardi, Scott Black, Christophe Boizard, Jean-Marc Bonmatin. Since the 1990s, 75% of the insect biomass has disappeared. The cause is the massive use of neonicotinoids, insecticides that diffuse into every plant cell. While scientific studies are accumulating to denounce the catastrophic consequences of the use of these neurotoxins, the multinationals that produce them are multiplying their efforts to cover their tracks. Financing of approximate studies, pressure on researchers and research institutes, intensive lobbying of regulatory authorities, all means are used to avoid regulations. Meanwhile, insects are disappearing at an unprecedented rate, even though they play key roles in pollination and food chains.
