    Why the Right Still Embraces Ivermectin

    Five years after the pandemic began, interest in the anti-parasitic drug is rising again as right-wing influencers promote it — and spread misinformation about it.Joe Grinsteiner is a gregarious online personality who touts the anti-parasitic drug ivermectin. In a recent Facebook video, he produced a tube of veterinary-grade ivermectin paste — the kind made for deworming horses.He gave the tube a squeeze. Then he licked a slug of the stuff, and gulped.“Yum,” Mr. Grinsteiner said in the Feb. 25 video, one of a number of ivermectin-related posts he has made that have drawn millions of views on Facebook this year. “Actually, that tastes like dead cancer.”Ivermectin, a drug proven to treat certain parasitic diseases, exploded in popularity during the pandemic amid false claims that it could treat or prevent Covid-19. Now — despite a persistent message from federal health officials that its medical benefits are limited — interest in ivermectin is rising again, particularly among American conservatives who are seeing it promoted by right-wing influencers.Mr. Grinsteiner, 54, is a Trump supporter and country music performer who lives in rural Michigan. He has claimed in his videos that ivermectin cured his skin cancer, as well as his wife’s cervical cancer. In a video last month, he said a woman told him her nonverbal autistic child had become verbal after using ivermectin. In a recent phone interview, Mr. Grinsteiner said that he takes a daily dose of ivermectin to maintain his general well-being.There is no evidence to support people taking ivermectin to treat cancer or autism. Yet Mr. Grinsteiner believes that the medical and political establishments just want to keep average people from discovering the healing powers of a relatively affordable drug.

    How a Crisis for Vultures Led to a Human Disaster: Half a Million Deaths

    The birds were accidentally poisoned in India. New research on what happened next shows how wildlife collapse can be deadly for people.To say that vultures are underappreciated would be putting it mildly. With their diet of carrion and their featherless heads, the birds are often viewed with disgust. But they have long provided a critical cleaning service by devouring the dead.Now, economists have put an excruciating figure on just how vital they can be: The sudden near-disappearance of vultures in India about two decades ago led to more than half a million excess human deaths over five years, according to a forthcoming study in the American Economic Review.Rotting livestock carcasses, no longer picked to the bones by vultures, polluted waterways and fed an increase in feral dogs, which can carry rabies. It was “a really huge negative sanitation shock,” said Anant Sudarshan, one of the study’s authors and an economics professor at the University of Warwick in England.The findings reveal the unintended consequences that can occur from the collapse of wildlife, especially animals known as keystone species for the outsize roles they play in their ecosystems. Increasingly, economists are seeking to measure such impacts.A study looking at the United States, for example, has suggested that the loss of ash trees to the invasive emerald ash borer increased deaths related to cardiovascular and respiratory illness. And in Wisconsin, researchers found that the presence of wolves reduced vehicle collisions with deer by about a quarter, creating an economic benefit that was 63 times greater than the cost of wolves killing livestock.“Biodiversity and ecosystem functioning do matter to human beings,” said Eyal Frank, an economist at the University of Chicago and one of the authors of the new vulture study. “And it’s not always the charismatic and fuzzy species.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
