A new groundbreaking German study proves that pesticides spread much further from the field than previously believed. A team of scientists led by Professor Dr. Carsten Brühl tested topsoil, vegetation, streams and puddles from 78 locations over a 180 km stretch, from remote areas in the UNESCO forests on the mountain ranges to the farmland in the Upper Rhine area. The research team detected a total of 63 pesticides. Almost all measurement sites were contaminated. Residues were found in 97% of the soil and vegetation samples, often in complex mixtures of several active ingredients. This cocktail of pesticides is especially problematic because interactions can occur and effects can be amplified. The worrying results are consistent with previous smaller-scale studies in the South Tirol area in Italy. Large scale and prolonged pesticide use is a major factor in the sharp decline in populations of insects and other organisms essential for farming, as highlighted in our biodiversity campaign.

Un récent article spécialisé paru dans la revue Nature établit un lien entre les virus zoonotiques, tels que le virus Ebola, le VIH et le virus du SRAS à l’origine du COVID-19, et la fragmentation voire la destruction, des forêts. Les auteurs montrent qu’avec le déclin de la biodiversité, les animaux qui subsistent sont les hôtes de maladies plus prolifiques.
