It’s been a while since I’ve heard much about the “beepocalypse”, but apparently many remain under the misapprehension that honeybee populations have languished under the threat of modern farming techniques. Some recent fake news on that subject appears at this link. There are two related contentions here, and both are false. One is that honeybee populations are dwindling. The other is the claim that productivity-enhancing insecticides used in modern agriculture are killing bees.

Bill Wirtz of the Brussels-based Consumer Choice Center notes the following:

“… looking at the statistics of the Food and Agriculture Organization of the United Nations, beehives are on the rise worldwide. The data show that as of 2020, there has been an increase of beehives by 17% since 2010, 35% since 2000, and 90% since 1961.”

He also points out that efforts to prove the wild bee population in the U.S. declined over the five years ending in 2013 were based on a model laden with assumptions, as opposed to actual statistics. In any case, even if it had been true, a five-year period is hardly proof of a secular decline. Both wild and managed bee populations go through cycles based on natural conditions, and in the case of managed bees, conditions in the market for honey. In fact, high honey prices could favor growth ahead in managed bee populations, though cost factors make that less certain.

As for the insecticides widely blamed for the beepocalypse, there is no real world, field-level evidence of any link to declining bee populations. In a separate article, Wirtz cites reports from the U.S. EPA and agencies in Canada and Australia finding that the widely-blamed neonicotinoids could not be linked to harms to bee colonies. This study found that “neonics” had no lethal or “sublethal” effects on honeybees at field-level dosages, despite reports of such effects in the lab. The lab work cited sort of reminds me of the outrageous tests that led to the saccharine scare of the 1970s, when the saccharine-equivalent of 800 sugar-free soft drinks a day was fed to lab rats. Dose dependence means everything under actual field conditions.

Randy Oliver of ScientificBeekeeping.com has written several thorough analyses of the impact of neonics on bees over the years. In 2012, he posted an important article entitled “The Extinction of the Honeybee?”, in which he reported that “… honeybees were thriving at Ground Zero of neonicitinoid use”. Neonics have definite advantages relative to older pesticides: they are much safer for humans, they are more effective at targeting insects that bore and suck sap, and they can be used as seed treatments with less leaching into the surrounding environment relative to sprays.

Oliver followed that up his first piece with two companion articles in which he documented issues related to regulation, testing regimes, the field applicability of tests, problems in methodology, and interpretation of results. He identified seed planting dust as a serious problem for bees, but one that is easily managed. In the second post, Oliver evaluated a number of characteristics of bee and colony health, including learning performance, orientation, foraging, immune function, social interaction, task allocation, and effects upon brood. He summarized his review thusly (his emphasis):

“Any number of scientists have diligently tried to find any sorts of sublethal effects of neonics on bees, but have failed to demonstrate adverse effects at the colony level at doses produced by seed.”

At the last link, Oliver discusses specific issues with respect to different crops, as well as other potential harms of neonics. However, seed treatments have never been implicated by researchers in bee colony collapse.

Finally, from a more recent presentation, Oliver reviews the history of bee population numbers and factors that drove them. That included infestation by two different parasitic mites in the 1980s and another pathogen in the early 2000s. These invasive waves led to use of the term Colony Collapse Disorder. While neonics had nothing to do with it, there were claims that it did. Oliver is not shy about noting other problems he identifies with the use of neonics, and he is strongly in favor of pest management approaches that rely less on pesticides. This is partly because farmers recognize the consumer resistance to pesticides, rational or otherwise. When neonics are applied properly, however, bee colony collapse is not one of those problems.

Honey prices were up strongly in 2021 (see here) and have remained strong in 2022 (here). That would bode well for the managed bee population. However, costs have increased sharply as well, blunting beekeeper incentives. Suppliers of beekeeping equipment are also facing higher costs. Given these pressures, it’s not clear whether the managed bee population will expand this year, but there is no threat to the long-term health of the bees in the proper use of neonics.

False claims that a certain class of pesticides threaten the world’s bee populations are commonplace, and we hear the same more recently about various species of birds. The origins of the “beepocalypse” rumor were not based on scientific evidence, but on a narrative that developed among environmental activists in response to a phenomenon called Colony Collapse Disorder (CCD) that began around 2006, roughly a decade after neonicotinoid pesticides (so-called neonics) replaced earlier, more toxic compounds as the pesticides of choice. But Jon Entine writes at The Genetic Literacy Project:

“What causes CCD? It still remains a mystery, in part. But researchers turned up historical examples of CCD-like bee die offs across the globe over hundreds of years, well before the introduction of pesticides, but activist groups would have none of it.”

CCD essentially tapered off by 2009, according to Entine, and the number of honeybee colonies are higher now that before the introduction of neonics. See Entine’s charts at the link showing changes in honeybee populations over time. In Australia, where the use of neonics has been especially heavy, bee populations have grown steadily and remain quite healthy.

Entine’s article provides a nice summary of the real and imagined threats to the world’s bee populations as well as distorted claims associated with normal winter die-offs. He provides a number of useful links on these subjects, and he summarizes research showing the lack of any real threat to bees from neonics:

“Over the past seven years, there have been a flood of studies about the potential impact of neonics on bees. Many small-scale, forced-feeding studies that generally overdosed bees with neonics found various negative effects; not a surprise, many entomologists have said, as they do not replicate real world impacts.

In contrast, a multitude of large-population field studies—the ‘gold-standard’ of bee research—have consistently demonstrated there are no serious adverse effects of neonic insecticides on honeybees at the colony level from field-realistic neonic exposure. …

By last year, even the Sierra Club—for years one of the leading proponents of the honeybee Armageddon narrative—was backpeddling, writing: ‘Honeybees are at no risk of dying off. While diseases, parasites and other threats are certainly real problems for beekeepers, the total number of managed honeybees worldwide has risen 45% over the last half century.'”

Then Entine turns his attention to another front in the war on pesticides: a Canadian study in which white-crowned sparrows were force-fed a mixture of seeds and pesticide via gavage — ie, through a tube:

“Only sparrows force-fed the highest dosage were affected, and then only temporarily. They stopped eating, quickly lost body weight and fat, became disoriented and paused their migratory flight—all after tube full of chemicals was forced down their throat and into their stomach. … That said, within a few days of what was likely a trauma-inducing experience, all recovered completely and continued their migration normally.”

Yet the authors reported that the very existence of some wild birds is threatened by neonics, and the media, always eager to report a crisis, ran with it.

Paul Driessen also describes the junk science underlying misleading narratives regarding pesticide use. It is a driving force behind legislation in the House and Senate that would ban the use of neonics in National Wildlife Refuges, where the Fish & Wildlife Service permits farmers to grow various crops. Driessen has some advice for Rep. Nydia Velázquez (D-NY), a sponsor of the legislation:

“She should also recognize potentially serious threats to bees, wildlife, soils, waters and plants in refuges from sources that she, her colleagues and their environmentalist and media allies routinely ignore: solar panels, for instance. Not only do they blanket many thousands of acres, allowing little to grow beneath or between them. They can also leach cadmium and other metals into soils and waters. They should no longer be built near wildlife refuges.

Finally, it’s not just bees. It’s also birds, and bats – which are already being killed and even eradicated in many areas by America’s 56,000 wind turbines. Imagine what Green New Deal turbine numbers would do.”

More perspective is offered in this excellent six-part (and growing?) “Pesticides and Food” series (all at the link) by Kayleen Schreiber:

  1. Has pesticide use decreased? Yes, dramatically in per capita and per unit of output.
  2. Have pesticides improved?  Yes, with dramatically lower toxicity, improved biodegradability, and lower use rates.
  3. How dangerous is glyphosate (a herbicide)? Not very. Covered in my last post. Glyphosate is only 1/10th as toxic as caffeine.
  4. How do organic pesticides compare to synthetic pesticides? It’s a mixed bag, with great variability across both classes. Organics are more toxic in some applications, and synthetics are more toxic in others.
  5. Soil health: Are synthetic pesticides more sustainable than “natural” organics?  Organics require more tillage, which creates sustainability problems.
  6. Pesticide residues — Something to worry about? The USDA finds little residue in its testing, with extremely low detection rates for both organics and synthetics.

 

 

The UN’s Mass Extinction Fiction

A big story early this month warned of mass extinctions and a collapse of the planet’s biodiversity. This was based on a report by the UN’s Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES). A high-level presentation of the data by IPBES was constructed in a way that is easily revealed as misleading (see below). But the first thing to ask about bombastic reports like this is whether the authors are self-interested. There is big money in promoting apocalyptic scenarios and public programs to avert them. Large government grants are at stake for like-minded scientists, and political power is at stake for biodiversity activists worldwide. Like many other scare stories reported as “news”, this one feeds into the statist political agenda of the environmental Left.

Exaggerated claims of species endangerment are not a new phenomenon. We’ve heard grossly erroneous forecasts of polar bear extinctions, frightening but false warnings of a “beepocalyse”, and faulty claims about declines in the population of African elephants. These are headline-grabbing and more thrilling to report than mourning the prospective loss of an obscure species of cave lichen. But a mass extinction is something else! Dan Hannon reminds us of the following:

“In 1980, for example, the Jimmy Carter administration distributed to foreign governments a report claiming that, by the year 2000, 2 million species would be wiped out. In fact, by 2010, there had been 872 documented extinctions.” 

Of course, that figure does not account for the multitude of new species discovered. There are many. Recent examples just gruesome enough to garner attention are the three new species of bird eater tarantulas discovered in 2017.

In the more general mass-extinction context of the IPBES report, the blame for the extremely pessimistic outlook is placed squarely on human activity. The authors allege CO2 emissions as the primary culprit, which is at best a theory and one at odds with the chief driver of extinctions during the industrial era. That is the introduction of non-native species into environments having flora or fauna unable to withstand new competitors. Matt Ridley elaborates:

“The introduction by people of predators, parasites and pests, especially to islands, has been and continues to be far and away the greatest cause of local and global extinction of native fauna.”

There is no question that the IPBES report on extinctions was intended to create alarm. As Gary Wrightstone demonstrates, the lack of rigor and misleading expositional techniques used in the report are a tell:

“… the data were lumped together by century rather than shorter time frames, which, as we shall see accentuates the supposed increase in extinctions. … The base data were derived from the International Union for Conservation of Nature and Natural Resources (IUCN) Red List, which catalogues every known species that has gone the way of the dodo and the carrier pigeon. Review of the full data set reveals a much different view of extinction and what has been happening recently.”

The more granular charts Wrightstone presents are indeed contrary to the narrative in the IPBES report. And Wrightstone also highlights the following in a postscript:

“In an incredibly ironic twist that poses a difficult conundrum for those who are intent on saving the planet from our carbon dioxide excesses, the new study reports that the number one cause of predicted extinctions is habitat loss. Yet their solution is to pave over vast stretches of land for industrial scale solar factories and to construct immense wind factories that will cover forests and   grasslands, killing the endangered birds and other species they claim to want to save.”

The enduring extinction racket is one among other fronts in the war on capitalism. The IPBES report must use the term “transformative” a thousand times, as it recommends “steering away from the current limited paradigm of economic growth“. Matt Ridley highlights the faulty attribution of alleged declines in biodiversity to “western values and capitalism”:

“On the whole what really diminishes biodiversity is a large but poor population trying to live off the land. As countries get richer and join the market economy they generally reverse deforestation, slow species loss and reverse some species declines.”

And Ridley also says this:

“A favourite nostrum of many environmentalists is that you cannot have infinite growth with finite resources. But this is plain wrong, because economic growth comes from doing more with less. So if I invent a new car engine that gets twice as many miles per gallon, I’ve caused economic growth but we’ll use less fuel. Likewise if I increase the yield of a crop, I need less land and probably less fuel too.”

It’s no coincidence that future extinctions foretold by IPBES are predicted to have drastic impacts on less-developed countries. It thus appears that IPBES exists in a happy synergy with the UN’s climate Intergovernmental Panel on Climate Change (IPCC), as well as proponents of the Paris Accord and the entire climate lobby. An objective that helps them garner support around the globe is to redistribute existing wealth to less-developed countries in the name of environmental salvation. That would prove a poor substitute for the kinds of free-market policies that would truly enhance prospects for economic growth in those nations.

The threat of mass extinctions is greatly exaggerated by the UN, IPBES, climate change activists, and members of the media who can’t resist promoting a crisis. Any diminished biodiversity we might experience going forward won’t be solved by limiting economic growth, as the IPBES report claims. Instead, advances in productivity, particularly in agriculture, can allow expansion of native habitat, as recent experience with reforestation and global greening demonstrates. This principle is as applicable to under-developed countries as anywhere else.

The kinds of centrally planned limits on human activity contemplated by the IPBES report are likely to backfire by making us poorer. Those limits would impose costs by misallocating resources away from things that people value most highly. They would also force people to forego the adoption of innovative production techniques, leading to the substitution of other resources, such as inefficient land use. And those limits would deny basic freedoms, including the unfettered use of private property.

The Bad News Industrial Complex

Matt Ridley had an interesting piece on his blog last month entitled “Bad News Is Sudden, Good News Is Gradual“. It’s about the timing of news, as stated, and it’s about our bias toward bad news more generally. There is no question that bad news tends to be more dramatic than good news. But with steadily increasingly lifespans, growing prosperity, and world poverty at an all-time low, surely good news must come as much or more frequently than bad. But good news can be inconvenient to certain narratives. It is therefore often ignored, and some other purported disaster is found as a substitute:

“Poverty and hunger are the business Oxfam is in, but has it shouted the global poverty statistics from the rooftops? Hardly. It has switched its focus to inequality. When The Lancet published a study in 2010 showing global maternal mortality falling, advocates for women’s health tried to pressure it into delaying publication ‘fearing that good news would detract from the urgency of their cause’, The New York Times reported. The announcement by Nasa in 2016 that plant life is covering more and more of the planet as a result of carbon dioxide emissions was handled like radioactivity by most environmental reporters.“

Tales of bad outcomes can be alluring, especially if they haven’t happened yet. In fact, bad things might even happen gradually, but dark visions of a world beyond the horizon impart a spooky sense of immediacy, and indeed, urgency. Ridley notes the tendency of people to regard pessimists as “wise”, while optimists are viewed as Pollyannas. And he recognizes that risk aversion plays an important role in this psychology. That brings me to the point I found most interesting in Ridley’s piece: the many vested interests in disasters, and disasters foretold.

Risk management is big business in an affluent society. There is a lot to lose, and a squeamish populace is easily cowed by good scare stories. The risk management and disaster-prevention narrative can be wrapped around any number of unlikely or exaggerated threats, serving the interests of the administrative state and private rent-seekers. One particular tool that has been most useful to this alliance is the precautionary principle. It is invoked to discourage or regulate activities presumed to pose risks to the public or to the environment. But there are three dimensions to the application of the precautionary principle: it provides a rationale for public funding of research into the risk-du-jour, for funding projects designed to mitigate its consequences, and for subsidizing development of alternative technologies that might help avoid or reduce the severity of the risk, often at great expense. The exaggeration of risk serves to legitimize these high costs. Of course, the entire enterprise would be impossible without the machinery of the state, in all its venality. Where money flows, graft is sure to follow.

Well-publicized disaster scenarios are helpful to statists in other ways. Risk, its causes, and its consequences are not distributed evenly across regions and populations. A risk thought to be anthropomorphic in nature implies that wealthier and more productive communities and nations must shoulder the bulk of the global costs of mitigation. Thus, the risk-management ethic requires redistribution. Furthermore, wealthier regions are better situated to insulate themselves locally against many risks. Impoverished areas, on the other hand, must be assisted. Finally, an incredible irony of our preoccupation with disaster scenarios is the simultaneous effort to subsidize those deemed most vulnerable even while executing other policies that harm them.

Media organizations and their newspeople obviously benefit greatly from the subtle sensationalism of creeping disaster. As Ridley noted, the gradualism of progress is no match for a scare story on the nightly news. There is real money at stake here, but the media is driven not only by economic incentives. In fact, the dominant leftist ideology in media organizations means that they are more than happy to spread alarm as part of a crusade for state solutions to presumed risks. There are even well-meaning users of social media who jump at the chance to signal their virtue by reposting memes and reports that are couched not merely in terms of risks, but as dire future realities.

Mitigating social risks is a legitimate function of government. Unfortunately, identifying and exaggerating risks, and suppressing contradictory evidence, is in the personal interest of politicians, bureaucrats, crony capitalists, and many members of the media. Everything seems to demand government intervention. Carbon concentration, global warming and sea level changes are glaring examples of exaggerated risks. As Ridley says,

“The supreme case of unfalsifiable pessimism is climate change. It has the advantage of decades of doom until the jury returns. People who think the science suggests it will not be as bad as all that, or that humanity is likely to mitigate or adapt to it in time, get less airtime and a lot more criticism than people who go beyond the science to exaggerate the potential risks. That lukewarmers have been proved right so far cuts no ice.”

Other examples include the “beepocalypse“, genetic modification, drug use, school shootings, and certain risks to national security. Ridley offers the consequences of Brexit as well. There, I’ve listed enough sacred cows to irritate just about everyone.

In many cases, the real crises have more to do with government activism than the original issue with which they were meant to reckon. Which brings me to a discomfiting vision of my own: having allowed the administrative state to metastasize across almost every social organ and every aspect of our lives, a huge risk to our future well-being is continuing erosion of personal and economic liberties and our ability to prosper as a society. Here’s Ridley’s close:

“Activists sometimes justify the focus on the worst-case scenario as a means of raising consciousness. But while the public may be susceptible to bad news they are not stupid, and boys who cry ‘wolf!’ are eventually ignored. As the journalist John Horgan recently argued in Scientific American: ‘These days, despair is a bigger problem than optimism.'”
