In the Atlantic Forest, the lowland tapir is at risk of extinction

PENSOFT PUBLISHERS

Lowland tapir populations in the Atlantic Forest in South America are at risk of almost complete disappearance, scientists have estimated. Weighing up to 250 kg, the animal can adapt to most habitats in South America—but its populations continue to decline across its range.

Today, its survival is seriously threatened: it can be found in just 1.78% of its original distributional range in the Atlantic Forest biome, which covers parts of Brazil, Argentina and Paraguay. The main long-term threat to its well-being is population isolation, as hunting and highways keep populations away from each other.

Urgent measures need to be taken to connect isolated populations and ensure the long-term conservation of tapirs, warn the authors of a new study on the distribution and conservation status of lowland tapirs in the South American Atlantic Forest, published in the open-access journal Neotropical Biology and Conservation.

The research was done by Kevin Flesher, PhD, researcher at the Biodiversity Study Center, Michelin Ecological Reserve, Bahia, and Patrícia Medici, PhD, coordinator of the Lowland Tapir Conservation Initiative, a project developed by the Institute for Ecological Research in Brazil, and chair of the Tapir Specialist Group at the Species Survival Commission in the International Union for Conservation of Nature.

"Of the 48 tapir populations identified during the study, between 31.3% and 68.8% are demographically unviable (low number of individuals), and between 70.8% and 93.8% of the populations are genetically unviable (low gene flow). Only 3-14 populations are still viable in the long run when both criteria are considered. The evidence suggests that with the appropriate conservation actions, the lowland tapir could be broadly distributed throughout the Atlantic Forest," says Kevin Flesher.

"Tapirs have low reproductive potential, including a long reproductive cycle with the birth of just one young after a gestation period of 13-14 months and intervals of up to three years between births. Our populational simulations clearly show how, in the case of small populations, even the loss of a single individual per year can result in rapid extinction of an entire local population," adds Medici.

Kevin Flesher dedicated 15 years to visiting 93 reserves in the Atlantic Forest, talking to people and analyzing 217 datasets, before he compiled the necessary data to design conservation actions that can ensure the survival of tapirs in the area.

The states of São Paulo and Paraná in Brazil have the largest number of remaining populations: 14 and 10, respectively. The two largest populations are in Misiones, Argentina, and in the neighboring Iguaçu and Turvo reserves, in Paraná and Rio Grande do Sul, Brazil.

"As far as our knowledge goes, there is no evidence of movement of tapirs between these populations," points out Medici.

The distance between population fragments, however, is not what is stopping them.

"The central problem is the multiple threats they face while crossing the habitat," explains Flesher. Highways are one major obstacle that limits the access of tapirs to forests with adequate habitat. "For example, the heavy traffic on highway BR-101 (which cuts the Brazilian Atlantic Forest from North to South) is a death trap to wildlife. Tapirs often die when attempting to cross it," explains Medici.

The construction of highways and expansion of traffic in and around natural areas is a serious threat to large tapir populations that might otherwise have the chance to thrive, like those in Misiones, Argentina, and Serra do Mar, Brazil.

"Roadkill is a significant cause of death in six of the eight reservations in which highways cross tapir populations, and the expansion of the roadway grid in the country threatens to cause population fragmentation in at least four populations,” points out Flesher. This is why finding ways to allow tapirs to cross highways safely is an urgent conservation priority.

The results of the study, however, give cause for “cautious optimism” for the future of tapirs in the area: after decades of dedicated conservation efforts, the situation is starting to improve.

"Despite these continuing challenges for tapir conservation, most populations appear to be stable or increasing and the conservation outlook for the species is better than several decades ago, when the first efforts to protect the species began," Kevin Flesher concludes.

SwRI collaborates to create sCO2 turbomachinery for concentrated solar power plant

DOE’s APOLLO program helped support project

Business Announcement

SOUTHWEST RESEARCH INSTITUTE

SAN ANTONIO — Jan. 17, 2022 — Southwest Research Institute worked with government and commercial collaborators to successfully develop and demonstrate full-scale turbomachinery for one of the world’s first supercritical carbon dioxide (sCO2) power systems for a concentrated solar power (CSP) plant. The technology combines sCO2 power cycles with integrated thermal energy storage.

The project was supported by the U.S. Department of Energy’s APOLLO program, which was created to improve performance and reduced the cost of electricity from CSP plants. The 10MW sCO2 turbomachinery has successfully completed performance and endurance tests in a closed-loop environment.

sCO2 is carbon dioxide held above a critical temperature and pressure, which causes it to act like a gas while having the density of a liquid. It’s also nontoxic and nonflammable, having been used in dry cleaning processes, low-GHG refrigeration systems, as well as to decaffeinate coffee.

The fluid properties in its supercritical state makes sCO2 a highly efficient fluid to generate power due to high density, low viscosity and favorable heat transfer properties.

“Advancing grid-scale energy storage is an important step to enabling full penetration of renewables into power generation. Utilizing sCO2 as a working fluid can increase the efficiency of a CSP plant by as much as 10 percentage points,” said Dr. Jason Wilkes, manager of SwRI’s Rotating Machine Dynamics Section. “The high efficiency of the sCO2 cycle also allows the turbomachinery to have a smaller footprint — it is 1/20th the size of a standard steam turbine, allowing for improved installation in most environments.”

CSP technology uses mirrors or lenses to concentrate a large amount of sunlight onto a receiver, which typically converts concentrated light into heat and extracts thermal energy to generate power using steam turbines. The system stores the energy as heat, which can then be converted to on-demand energy using sCO2 power cycles, improving efficiency and reducing operating costs.

“sCO2 power cycle technology is a fraction of the size of conventional turbomachinery, offering improved performance for numerous applications. The successful MW-scale demonstration of sCO2 technology at full-cycle conditions is an exciting milestone,” said Dr. Tim Allison, director of SwRI’s Machinery Department.

SwRI and Hanwha Power Systems, a global energy equipment company with headquarters in South Korea, developed and demonstrated the new integrally geared sCO2 turbomachinery tested at full-scale compressor conditions and full-pressure full-temperature testing of the turbine at unprecedented MW-scale conditions of up to 720 °C and 275 bar. The system is planned to be integrated into a CSP pilot plant at a future date.

Enhanced statistical models will aid conservation of killer whales and other species

Understanding wild animal behaviors is important when building species conservation plans, however following animals can be expensive, dangerous, or sometimes impossible in the case of animals that move underwater or into areas we can’t easily reach

Ecologists need to understand wild animal behaviours in order to conserve species, but following animals around can be expensive, dangerous, or sometimes impossible in the case of animals that move underwater or into areas we can’t reach easily.

Scientists turned to the next best thing: bio-logging devices that can be attached to animals and capture information about movement, breathing rate, heart rate, and more.

However, retrieving an accurate picture of what a tagged animal does as it journeys through its environment requires statistical analysis, especially when it comes to animal movement, and the methods statisticians use are always evolving to make full use of the large and complex data sets that are available.

A recent study by researchers at the Institute for the Oceans and Fisheries (IOF) and the UBC department of statistics has taken us a step closer to understanding the behaviours of northern resident killer whales by improving statistical tools useful for identifying animal behaviours that can’t be observed directly.

“The thing we really tackled with this paper was trying to get at some of those fine-scale behaviours that aren’t that easy to model,” said Evan Sidrow, a doctoral student in the department of statistics and the study’s lead author. “It’s a matter of finding behaviours on the order of seconds—maybe 10 to 15 seconds. Usually, it’s a matter of a whale looking around, and then actively swimming for a second to get over to a new location. We are trying to observe fleeting behaviours, like a whale catching a fish.”

The research team improved a statistical tool that is based on what is called a hidden Markov model, which is helpful for unlocking the mysteries hidden inside animal movement datasets.

“Traditional hidden Markov models break down at very fine scales,” Sidrow said. “That’s because there’s structure in the data you can’t capture using the basic type of hidden Markov model. We’re trying to capture it with this model—we’re trying to account for this ‘wigglyness' that a traditional hidden Markov model wouldn’t be able to account for.”

In other words, now that tags can collect data almost continuously, researchers are left with an immense number of data points taken fractions of seconds apart, and traditional Markov models and statistical methods struggle to interpret such high-frequency information—hence the need for the more advanced Markov model proposed in the study.

Using the enhanced hidden Markov models, the team found some undiscovered northern resident killer whale behaviours. The whale they used to develop the model preferred to save energy by gliding through the water when making deep dives, and when it was closer to the surface, it moved more actively, accelerating faster and ‘fluking’ its tail more often.

Understanding these diving patterns will be crucial for whale conservation because it will help researchers learn how much energy the whales require to sustain themselves.

And the method’s applications extend far beyond whale movement data, according to Sidrow.

“It could be applied to pretty much any animal movement data,” he said. "If you’re tagging animals and you want to understand fine-scale behaviours, then this method that could be useful—even for things like the flapping of birds’ wings.”

It could even prove useful in areas outside of ecology, such as determining when machines are likely to break by classifying when the parts inside of them are vibrating abnormally.

The work is one of the first steps on the road to fully understanding why southern resident killer whales are not faring as well as their northern counterparts, according to Dr. Marie Auger-Méthé, senior author of the study and an assistant professor in the department of statistics and the Institute for the Oceans and Fisheries.

“Using our methods to detect when the animals are catching prey and to model their energy expenditure will be key to understanding the differences between these neighbouring whale populations,” she said.

The next goal is to understand when the whales are capturing prey and applying the models to both northern and southern resident killer whale populations to see how they are behaving differently.

“The paper offers many ‘building block’ solutions that can be used together or independently,” Dr. Auger-Méthé said. “In essence, we are providing a toolbox to researchers using high-frequency movement data, and other similar high-frequency time series.”

Inciting instead of coercing, «nudges» prove their effectiveness

A team from the UNIGE demonstrates that certain soft incentive techniques, known as «nudges», are effective in getting people to change their behaviour.

Peer-Reviewed Publication

UNIVERSITÉ DE GENÈVE

Developed by the American economist Richard Thaler in the late 2000s, the theory behind «nudging» theory is based on the principle that our choices are not only determined by our ability to reason, but are also influenced by certain biases such as our emotions, our memories, the opinions of others or the configuration of our environment. Focusing on these elements can therefore be more effective in getting us to change certain behaviours than a ban or an awareness-raising campaign.

In the behavioral sciences, researchers call this a modification of the “choice architecture». This is done, for example, when in a company cafeteria the healthiest dishes are deliberately placed at the top of the menu to encourage customers to select the option that is most beneficial to their health, without infringing on their freedom to choose. As a result, this type of intervention is attracting increasing interest from both the scientific community and public authorities.

Over 450 strategies analyzed

Despite the growing popularity of nudges, their performances had not yet been studied in their entirety. By performing a meta-analysis (a statistical approach aimed at synthesizing the results of numerous studies), a research team from the University of Geneva (UNIGE) has succeeded in demonstrating the effectiveness of “nudges” and identifying the areas in which they are most relevant. «We have collected more than 200 scientific articles published over the last 15 years on the subject, which represent more than 450 ‘nudge’ strategies,» says Stéphanie Mertens, the study’s first author and a researcher at the Consumer Decision and Sustainable Behavior Laboratory of the Department of Psychology in the Faculty of Psychology and Educational Sciences at the UNIGE.

To carry out this study, the researchers classified the nudges described in this scientific literature into three groups: «information», «structure» and «assistance». In the first set, they grouped interventions whose objective is to inform individuals in order to motivate them to make certain choices, such as the «nutri-score» labels found on certain food products. In the second set, they grouped techniques that deal with the structure of an environment. This is the example (cited above) of highlighting certain meals in a cafeteria menu.

In the third set, they classified nudges involving a form of commitment, as in the case of a person who stops smoking and informs those around him or her. When informed, the people around him or her take on the function of a «safeguard» in the choice architecture of the abstinent smoker.

Highly effective for food choices

The scientific team concluded that all three groups of nudges are effective. They note, however, that the techniques in the second group («structure») are the most effective. «Within these groups, we also compared different areas of application, such as health, finances or energy consumption. In the end, we found that nudges work best in the area of food», explains Tobias Brosch, Director of the Consumer Decision and Sustainable Behavior Laboratory. Tobias Brosch and his team have also observed disparities in the quality of the studies produced on the subject over the years. «It is imperative that the overall study quality increases because of the impact that nudges can have on the daily lives of citizens,» he explains.

All of the synthesized data is now available to researchers. But this study is also intended to become a reference document for policymakers who wish to implement these new practices. «However, it is important to bear in mind that nudges are powerful tools, as our research shows. Nudges must therefore be used wisely and within the framework of democratic and transparent processes,» concludes the researcher.

Improving reading skills through action video games

An Italian-Swiss team demonstrates children reading skills can be improved through a novel child-friendly action video game

Peer-Reviewed Publication

UNIVERSITÉ DE GENÈVE

Decoding letters into sound is a key point in learning to read but is not enough to master it. “Reading calls upon several other essential mechanisms that we don’t necessarily think about, such as knowing how to move our eyes on the page or how to use our working memory to link words together in a coherent sentence,” points out Daphné Bavelier, a professor in the Psychology Section of the Faculty of Psychology and Educational Sciences (FPSE) at the UNIGE. “These other skills, such as vision, the deployment of attention, working memory, and cognitive flexibility, are known to be improved by action video games”, explains Angela Pasqualotto, first author of this study, which is based on her PhD thesis at the Department of Psychology and Cognitive Science of the University of Trento under the direction of Professors Venuti and De Angeli.

A child-friendly action video game to support learning

With this in mind, a video game was designed that combines action video games with mini games that train different executive functions, such as working memory, inhibition and cognitive flexibility, functions that are called upon during reading. “The universe of this game is an alternative world in which the child, accompanied by his Raku, a flying creature, must carry out different missions to save planets and progress in the game”, Angela Pasqualotto adds. The idea is to reproduce the components of an action game, without incorporating violence, so that it is suitable for young children. “For example, the Raku flies through a meteor shower, moving around to avoid those or aiming at them to weaken their impact, while collecting useful resources for the rest of the game, a bit like what you find in action video games.”

The scientists then worked with 150 Italian schoolchildren aged 8 to 12, divided into two groups: the first one played the video game developed by the team, and the second one played Scratch, a game that teaches children how to code. Both games require attentional control and executive functions, but in different manners. The action video game requires children to perform tasks within a time limit such as remembering a sequence of symbols or responding only when the Raku makes a specific sound while increasing the difficulty of these tasks according to the child’s performance. Scratch, the control game, requires planning, reasoning and problem solving. Children must manipulate objects and logical structures to establish the desired programming sequence.

“First, we tested the children’s ability to read words, non-words and paragraphs, and also we conducted an attention test that measures the child’s attentional control, a capacity we know is trained by action video games,” explains Daphne Bavelier. The children then followed the training with either the action video game or the control game, for six weeks, two hours a week under supervision at school. Children were tested at school by clinicians of the Laboratory of Observation Diagnosis and Education (UNITN).

Long-term improvement in reading skills

Shortly after the end of the training, the scientists repeated the tests on both groups of children. “We found a 7-fold improvement in attentional control in the children who played the action video game compared to the control group”, says Angela Pasqualotto. Even more remarkably, the research team observed a clear enhancement in reading, not only in terms of reading speed, but also in accuracy, whereas no improvement was noted for the control group. This improvement in literacy occurs even though the action video game does not require any reading activity.

“What is particularly interesting about this study is that we carried out three further assessment tests at 6 months, 12 months and 18 months after training. On each occasion, the trained children performed better than the control group, which proves that these improvements were sustained,” Angela Pasqualotto says. Moreover, the grades in Italian of the trained children became significantly better over time, showing a virtuous improvement in learning ability. “The effects are thus long-term, in line with the action video game strengthening the ability to learn how to learn,” says Daphne Bavelier.

Within the framework of the NCCR Evolving Language and in collaboration with Irene Altarelli (co-author of the article and researcher at LaPsyDE, University of Paris), the game will be adapted into German, French and English. “When reading, decoding is more or less difficult depending on the language. Italian, for example, is very transparent – each letter is pronounced – whereas French and English are quite opaque, resulting in rather different learning challenges. Reading in opaque languages requires the ability to learn exceptions, to learn how a variety of contexts impacts pronunciation and demands greater reliance on memorization,” comments Irene Altarelli. Will the benefits of action video games on reading acquisition extend to such complex learning environments as reading in French or English? This is the question that this study will help answer. In addition, the video game will be available entirely at home, remotely, as will the administration of reading and attention tests, in order to complement school lessons, rather than taking time out of school hours.

Strong evidence shows Sixth Mass Extinction of global biodiversity in progress

The history of life on Earth has been marked five times by events of mass biodiversity extinction caused by extreme natural phenomena. Today, many experts warn that a Sixth Mass Extinction crisis is underway, this time entirely caused by human activities.

A comprehensive assessment of evidence of this ongoing extinction event was published recently in the journal Biological Reviews by biologists from the University of Hawai‘i at Mānoa and the Muséum National d’Histoire Naturelle in Paris, France.

“Drastically increased rates of species extinctions and declining abundances of many animal and plant populations are well documented, yet some deny that these phenomena amount to mass extinction,” said Robert Cowie, lead author of the study and research professor at the UH Mānoa Pacific Biosciences Research Center in the School of Ocean and Earth Science and Technology (SOEST). “This denial is based on a biased view of the crisis which focuses on mammals and birds and ignores invertebrates, which of course constitute the great majority of biodiversity.”

By extrapolating from estimates obtained for land snails and slugs, Cowie and co-authors estimated that since the year 1500, Earth could already have lost between 7.5 and 13% of the two million known species on Earth – a staggering 150,000 to 260,000 species.

“Including invertebrates was key to confirming that we are indeed witnessing the onset of the Sixth Mass Extinction in Earth’s history,” said Cowie.

The situation is not the same everywhere, however. Although marine species face significant threats, there is no evidence that the crisis is affecting the oceans to the same extent as the land. On land, island species, such as those of the Hawaiian Islands, are much more affected than continental species. And the rate of extinction of plants seems lower than that of terrestrial animals.

Unfortunately, along with science denial taking a foothold in modern society on a range of issues, the new study points out that some people also deny that the Sixth Extinction has begun. Additionally, others accept it as a new and natural evolutionary trajectory, as humans are just another species playing their natural role in Earth’s history. Some even consider that biodiversity should be manipulated solely for the benefit of humanity – but benefit defined by whom?

“Humans are the only species capable of manipulating the biosphere on a large scale,” Cowie emphasized. “We are not just another species evolving in the face of external influences. In contrast, we are the only species that has conscious choice regarding our future and that of Earth’s biodiversity.”

To fight the crisis, various conservation initiatives have been successful for certain charismatic animals. But these initiatives cannot target all species, and they cannot reverse the overall trend of species extinction. Nonetheless, it is essential to continue such efforts, to continue to cultivate a wonder for nature, and to document biodiversity before it disappears.

“Despite the rhetoric about the gravity of the crisis, and although remedial solutions exist and are brought to the attention of decision-makers, it is clear that political will is lacking,” said Cowie. “Denying the crisis, accepting it without reacting, or even encouraging it constitutes an abrogation of humanity’s common responsibility and paves the way for Earth to continue on its sad trajectory towards a Sixth Mass Extinction.”

15-minute tumble dry can release hundreds of thousands of microfibers into the air

“To minimize the release of these microfibers into the air, an appropriate engineered filtration system should be developed and adopted as an effective control measure for individual household driers."

Olivia Rosane

Every time you stick a load of clothes into a tumble dryer, you may be releasing hundreds of thousands of microfibers into the air.

That’s the conclusion of a new study published in Environmental Science & Technology Letters Wednesday, which measured the fibers that escape from a household vented tumble dryer into the surrounding air.

“The results suggest that driers of this type are a potential source of air contamination by microfibers, releasing 433,128–561,810 microfibers during 15 min of use,” the study authors concluded.

Microfibers can come from either natural fabrics like cotton or synthetic ones like polyester, SciTechDaily explained. The latter is an example of microplastic pollution, and previous research has focused on how washing machines may contribute to the ocean plastic pollution crisis, as microfibers slough off in the wash and enter wastewater systems, eventually reaching the ocean. Researchers estimate that washing machines release two garbage trucks worth of microplastics into European oceans every day.

The new research, however, focused on the second half of the washing and drying process, and on how microfibers could travel through vents to reach the air. This is a concern because these fibers could collect organic or inorganic compounds and transport pollutants. Understanding whether or not dryers contribute to the problem is essential for resolving it.

“Once we know the source, we can begin to control it using simple methods,” study lead author Professor Kenneth Leung, who directs the State Key Laboratory of Marine Pollution (SKLMP) and the department of chemistry at City University of Hong Kong, told The Guardian.

SchiTech Daily explained how the researchers tested whether tumble dryers were a source of air pollution:

The researchers separately dried clothing items made of polyester and those made of cotton in a tumble dryer that had a vent pipe to the outdoors. As the machine ran for 15 minutes, they collected and counted the airborne particles that exited the vent. The results showed that both types of clothing produced microfibers, which the team suggests comes from the friction of clothes rubbing together as they tumbled around.

Overall, the researchers estimated that the average Canadian household dryer releases between 90 and 120 million microfibers into the air every year.

There was a difference between the cotton and polyester microfibers however: The larger the load, the more polyester fibers were released. But the size of the load did not matter for cotton clothing. Researchers hypothesized this was because cotton microfibers tend to clump together, which means they don’t escape into the air as easily. Cotton microfibers are also less of a concern because they can “decompose in the environment relatively quickly,” Leung told The Guardian.

To keep microplastics out of the environment, Leung and his team have already designed a 3D-printed filter for washing machines and are working on another one for dryers.

However, the researchers said the clothing industry should also work to develop more sustainable fabrics.

How the populist right twists leftwing ideas to appeal to voters

"The fact that the populist right feels the need to pretend they embrace so many progressive ideas shows that the left can win."

Derek Royden

January 14, 2022

SOURCENationofChange

One of the more interesting aspects of rightwing populism, especially in the form it’s taken in the United States, is its use of traditionally leftist talking points for reactionary political ends. This is a smart strategy as leftist ideas are broadly popular, especially when directed at the unaccountable power of big business and its servants in the political class.

Part of the appeal of someone like Tucker Carlson is that he pretends to be on the side of the (white) working class (who he’s started calling ‘legacy Americans’ in an obvious racist dog-whistle) against ‘elites’ and corporations. He’s able to pull this off by being very particular in terms of the businesses he goes after.

A good example of this is offered by the ongoing critique of ‘Big Tech’ by pundits like Carlson, which is often portrayed in their media as unfairly censoring ‘conservative’ views. These arguments accelerated when the former U.S. president lost access to his Twitter account after the events of January 6th at the U.S. Capitol. While this is mostly the result of him being out of office, Donald Trump’s social media bans seem to have impacted his day to day influence over his MAGA followers and ability to steer the news cycle.

While there’s lots to criticize about this huge and varied industry that could encompass everything from app focused startups to industrial giants like Sony and IBM, ‘Big Tech’ for conservative commentators is mainly the larger social media sites, platforms they argue they are entitled to say and post anything they want to on due to the free speech guarantees of the country’s 1st Amendment.

Although there have been a number of knockoffs like Parler, Gab and Gettr that are intended to directly connect to rightwing audiences, none have taken off enough to compete with older platforms in terms of the number of people using them. These platforms have also tended to be less secure than those that came before them, with Gettr almost immediately hacked upon its launch.

Another problem for users of these sites seems to be the fact that both centrist liberals and the left are almost entirely absent from them, meaning there are no opportunities to troll and ‘own the libs’, which seems to be one of the main things much of this audience enjoys about social media just as they did earlier with the comments sections on news sites.

It’s hard to get into an argument when everyone agrees with you.

Further, while the 1st amendment is still the global standard in terms of the rights it bestows, including the right to protest, it only protects speech from government interference and doesn’t expand these protections to private enterprises. Companies can police speech however they want and did so long before the advent of social media. One example of this is the right of a book publisher to decide what to print and what not to.

These social media companies, which are international in scope and must be careful about local laws, craft their own terms of service (though enforcement can be lax) and users are expected to abide by rules against things like hate speech and medical misinformation.

Despite these rules, it usually takes a long time for rightwing influencers to face consequences for even the most outrageously bigoted commentary. Part of this may be the result of a lack of moderation by human beings, who are more able to understand nuances like satire, but a greater one seems to be money, with those content creators with large numbers of subscribers or followers less likely to face consequences for breaking the rules established by the terms of service they agreed to when they joined. In the U.S., there is also the protection offered to these companies by Section 230 of the country’s Communications Decency Act, which frees them from liability for what their users post.

If one looks at the most popular political voices on the largest of these networks, Facebook, they’re all on the right, exposing the lie in the right’s criticism of ‘Big Tech’ as being controlled by the progressive left rather than the same kinds of business interests that control just about everything else in most Western democracies.

Take the case of failed comedian Steven Crowder, whose Youtube channel has over 5 and a half million subscribers. The former voice actor for the Canadian animated children’s show “Arthur”, where he somewhat ironically played a character called “The Brain”, consistently attacks Black Lives Matter activists, feminists and those fighting for the rights of trans and other LGBTQ+ communities.

It does seem that Crowder, who at the end of 2021 received a 2 week suspension from Youtube for hate speech, actually wants a permanent ban so that he can claim he’s been ‘cancelled’ and use this to raise more money from his fans while growing his other platforms like Rumble, a Toronto based site that seeks to be the video streaming platforn for the far right.

The left in general takes a more nuanced approach to arguments against these Big Tech companies, understanding that deplatforming almost always applies to them as well and that these companies will not hesitate to go after progressive voices in the interest of ‘fairness’. Most also understand that bans are just the most powerful tool available to the companies to silence those deemed outside of the mainstream, with unaccountable algorithms determining how far a post travels online.

An obvious solution to this, which would ensure the 1st amendment would apply to users of these sites in the United States would be to make these social networks public utilities or at least regulate them to ensure fair access for all, solutions free market loving rightwingers would probably have a hard time backing.

More dangerous than these ‘free speech’ battles is the global far right’s new found dislike for ‘Big Pharma’, which is being weaponized by some commentators to argue against Covid 19 vaccination campaigns.

There are legitimate criticisms that can be made about these massive companies, not the least of which is that Americans pay far more for life saving drugs than citizens of other countries like Canada or the UK. The anger against Big Pharma seems more legitimate than the ire directed at Big Tech considering how the opioid crisis hit red states as hard blue ones, devastating many of these communities. Still, this righteous anger is being misdirected against safe, freely available vaccines that have been shown to prevent hospitalizations and death from the novel coronavirus.

Just as QAnon did in 2020 with the hashtag ‘Save the Children’, the overwhelmingly rightwing anti-vaccine crowd have decided to co-opt another slogan, “My body, my choice” from those fighting for women’s reproductive freedom. This is all the more despicable considering that many of those using the slogan oppose a woman’s right to choose and have control over her own body, rights that seem more imperiled than ever at present.

Always prone to contradicting themselves, many of the same rightwing commentators that express scepticism about vaccines also tout an ever evolving list of unproven miracle cures from hydroxychloriquine to ivermectin to Viagra. All of these drugs produced by… Big Pharma.

What should really scandalize the public is the fact that companies like Pfizer and Moderna received billions of dollars in taxpayer money and benefited from the work of publicly funded scientists and agencies but see no reason not to demand full ownership of the vaccines and the huge profits to be derived from them. This has in turn ensured unequal distribution, with poorer countries in the global south unable to provide the shots to their populations while citizens in richer countries receive boosters, a situation that might extend the pandemic as new variants emerge in these places.

Personally, I am not a believer in the idea that progressives should expend resources and energy trying to pull the far right to our side but the left should definitely be ready to point out their hypocrisy and the inconsistencies in their arguments in order to win over people sitting on the fence. After all, there are more non voters than supporters of any political party in most Western democracies.

Culture war talking points aside, the fact that the populist right feels the need to
