Do people not realise that in a world without insects buzzing, there'll be no birds singing and no flowers blooming? Or do they simply no longer care so long as their smartphones continue to receive a signal?
Research data gathered by scientists and dozens of amateur entomologists from nature reserves across Germany that indicates the number of flying insects has fallen by around 75% over the last 30 years is certainly shocking, but hardly surprising to anyone old enough to remember when there were not only plenty of bees, butterflies and beetles in the backgarden, but also other invertebrates such as worms, slugs, and snails (not to mention the larger creatures that prey on these things).

The cause of this huge - and potentially catastrophic - decline is, apparently, unclear. But, of course, we all know in our hearts what (and who) is to blame for the destruction of habitat and widespread use of pesticides on an industrial scale for decades ... Oh, the humanity!
As the authors of the study conclude, this largely unacknowledged loss of insect biomass must henceforth be taken fully into account when evaluating ecosystems and, ultimately, the sustainability of life on earth in all its astonishing diversity.
Otherwise, the ultimate selfie will be taken by der letzte Mensch alone in a lifeless world.
