Ed Yong in The Atlantic:
In 1828, a teenager named Charles Darwin opened a letter to his cousin with “I am dying by inches, from not having anybody to talk to about insects.” Almost two centuries on, Darwin would probably be thrilled and horrified: People are abuzz about insects, but their discussions are flecked with words such as apocalypse and Armageddon.
The drumbeats of doom began in late 2017, after a German study showed that the total mass of local flying insects had fallen by 80 percent in three decades. The alarms intensified after The New York Times Magazine published a masterful feature on the decline of insect life late last year. And panic truly set in this month when the researchers Francisco Sánchez-Bayo and Kris Wyckhuys, having reviewed dozens of studies, claimed that “insects as a whole will go down the path of extinction in a few decades.” The Guardian, in covering the duo’s review, wrote that “insects could vanish within a century”—a crisis that Sánchez-Bayo and Wyckhuys believe could lead to a “catastrophic collapse of nature’s ecosystems.”
I spoke with several entomologists about whether these claims are valid, and what I found was complicated.
