Wednesday, 23. May 2018 - A number of chemical plant protection products, also known as pesticides, show harmful effects on ecosystems and biodiversity in their current use. Besides climate change, changes in global nutrient cycles and habitat destruction through altered land-use, the utilization of pesticides has also led to a dramatic loss of biodiversity. This is explained by a group of experts in the discussion paper published today by the National Academy of Sciences Leopoldina "The Silent Spring - On the need for sustainable plant protection". The scientists call for more comprehensive approval procedures for pesticides to better control their environmental implications.
