I'll take bugs over road salt any day. Having said that, there have been reports in the news lately about a decline in the insect population in North America. One article I read cited a study in which, over the years, scientists drove a car down the same road over and over. As time went on they counted fewer and fewer dead bugs on the windshield of the car. That's a simple and brilliant way to count insect populations. Now, as more and more EV's get out on the road, maybe, just maybe, insects will make a comeback. Remember, fewer insects = fewer birds, and that's just the start of things.
