Nano-pesticides: A great challenge for biodiversity?

Problems such as food shortages in the world, serious soil nutrient loss, and residues of pesticides in the environment have put enormous pressure on humans and the environment. In order to improve the yield and quality of food and alleviate the pressure of traditional pesticides on the environment, nano-pesticides have appeared and have been widely used due to their great role in saving agricultural costs, increasing the output of agricultural products, improving the nutrition and shelf life of foods, and achieving precision agriculture. However, the impact of nano-pesticides on biodiversity is still lacking clear research. We discuss here whether the use of nano-pesticides is a great challenge for biodiversity.
