In an earlier post, I discussed an article in the New York Times about the coming of the bugs that would invade our food supply. However, the Times is now reporting on the results of the Krefeld Study that found that all insects have been in sharp decline over the past 27 years. What gives? The reality is that bugs that can harm us are on the rise (ticks, mosquitoes, food pests) whereas the bugs that feed the birds and reptiles (the pollinators, etc.) are headed for extinction. We seem to have the worst of both worlds.
Not convinced? Have you noticed fewer bugs on your windshield and front bumper after driving during dusk over the past two decades? Entomologists call this the windshield phenomenon. I too have noticed far fewer bugs on my
car and aircraft windshields when operating during dusk.
Scientists previously thought that this loss of insects was due to loss of habitat. Although this is a cause, climate change is the major reason for their decline. While you might think fewer insects are a good thing, taking them out of the biosphere mix is affecting our food supply (i.e., lack of pollination) and other ways not yet evident. Everything connects, take one out and the impacts ripple.
