We ignore the wipeout of insects at our peril

After the banking royal commission targeted mortgage brokers’ secret kickbacks last month, the industry retaliated. Its Grim Reaper-style advert showed an anxious family facing an endless corridor without choice or deviation. Imagine a world without mortgage brokers, the voiceover exhorted, as though that were inconceivable. Yet – such is our species’ self-absorption – no one wasted advertising dollars on a possible extinction, revealed days earlier, that’s exponentially more worrisome: the end of insects.
Insects are often held by the eco-minded (including the UN) as a solution to world hunger. There are insect cookbooks and insect-eating Ted talks. The catch, of course, is that mass insectivorism presumes precisely the kind of destructive, industrial monoculture that has turned food-production into the planetary eco-crisis we have. But there’s also this. On current trends there may not be any bugs, period – depriving us not only of crunchy six-legged comestibles but of virtually all food except (perhaps) the synthetic.
The new report, Worldwide Decline of the Entomofauna, by Australian biologists Sanches-Bayo and Wyckhuys, collated 73 longitudinal insect population studies to identify a single downward trend: continuing decline in many insect species globally over decades. “Over 40 per cent of insect species are threatened with extinction,” it says. The worst affected are those upon which world agriculture most relies yet which it also most mistreats: butterflies, moths, bees and dung-beetles.
It’s an old, old story, this prioritising of profit or convenience over nature, usually cloaked by “demand”. But in the choice between insects and mortgage brokers? Reckon I’ll follow the honey. https://www.canberratimes.com.au/national/honey-we-shrunk-the-bee-and-insect-species-that-feed-us-20190307-p512g3.html
