Something I find of concern is that as a child (and that was not in the Jurrasic era) There were a great many more insects and frogs about, including spiders. We have almost no spiders around the house. That is due to the geckos and Green Frogs.

However, when driving on the highways back in 1974 and prior to that, there were hundreds of insect collisions against the windscreen. It was necessary to clean the windscreen after a few hours of driving. Often when pulling into a service station a bird or two would pick off the insects from the front of the car.
Driving in rain was good. No insects to clean off.
These days I hardly have any insect strikes. I'm discounting the occasional locust plague or whatever.
Flying insect invasions into the house was common in the 50's & 60's. Now there may only be a few ants or a few Christmas beatles. The numbers are nothing like what it used to be.
Could it mean a situation like the proverbial canary in the mine?
Anyone else notice these changes?
Cheers
