So just to be clear: your theory (which has absolutely no evidence whatsoever to support it, and is entirely your personal anecdotes of which there's no causal relationship established whatsoever) refutes both broad evidence of how much damage pesticides do to outside of the target species (and to humans, and birds) but also refutes extensive scientific evidence that we are living through a time of massive ecological die-offs of species?
Let me guess, you live in rural America?
I would bet they don't live rurally or havent been alive very long. Anyone rural alive over the last 30 years shouldve noticed a decline everywhere around them....would also expect them to notice bugs are different by the road to in the fields to by the ponds, and that different times of year, weather etc, changes which bugs are out and how many are out...its harder to notice these things in suburbs or cities.
