Scorpions are "taking over" Brazil's cities, scientists warn in the journal Frontiers in Public Health. And this "silent and escalating" crisis includes a huge rise in stinging incidents, some of them fatal.
The deadly stings are often from Brazilian yellow scorpions, known for their extremely toxic venom. The exploding scorpion population is tied to climate change and unchecked human development, and the infestation might already be impossible to stop.
More than 1.1 million scorpion stings were recorded in Brazil between 2014 and 2023, with the reported stings jumping by 155% over that decade, the researchers said. The surge in numbers is "driven by rapid, unplanned urbanization," said The Guardian. The sprawl of "high-density housing" encroaches on scorpions' natural habitats in the wild and "poor waste disposal" creates new environments where they can "thrive."
The Brazilian government seems "ill-equipped" for the "Herculean, if not downright impossible" task of tackling the infestations, with no plan other than "tepid" efforts to train health officials in "scorpion risk," Hamilton Coimbra Carvalho, a researcher at the University of São Paulo, said at The Conversation in 2019. He predicted it was probably already "too late" to stop the spread of scorpions across Brazil's cities.
But the arachnids are "not our enemies," Manuela Berto Pucca, from São Paulo State University, told The Guardian. As "part of the natural world," they play "essential ecological roles," from "controlling pest populations to maintaining biodiversity." And, crucially for the humans who live alongside them, they "act defensively, not offensively." |
