I'm living in a central european country with lots of agriculture, and the decrease of insects in the past few years is so obvious it's pretty scary.
no surprise tho, since most of the landscapes are insecticide soaked monoculture fields without any wild spots. some farmers tend to have 'green areas' inbetween their fields, but they're mostly so tiny it's a joke.
Some people I know have an industrial canola plant next to their property, and there isn't growing or living ANYTHING in between the canola plants.nothing. no mosses or tiny weeds or whatever stubburn small plants who normally always grow somewhere inbetween.
since there have been bans on a few specific pesticides, the only plant other than canola which survives there now is a bit of wild chamomille.
