Here is another interesting article from March 2022 (Link). EPA in the USA has approved the use of imidacloprid, thiamethoxam, clothianidin, and dinotefuran for the next 15 years.
These chemicals have been banned in the European Union and restricted in Canada as they have been proven to be devastating on bees, butterflies, and other pollinating insects. They started being sold in the mid 90s and their usage has intensified since.
Is the drop in pollinators a valid concern or is it overblown noise in an ever noisy world?
