Some argue that transgender females should be banned from competing with women in sports, while others think such bans are unfair, as the NCAA and other organizations try to keep up with research on how testosterone affects performance.
Ashley O’Connor, who was biologically male at birth but identifies as female, decided to compete in badminton as a girl during her senior year of high school in Downers Grove, Illinois. There was no team for boys, and a female friend and badminton player “practically bullied me into joining” the girls’ team. O’Connor, who is 18 and taking hormone replacement therapy for her gender transition, recalled that “it was easily one of the best decisions I have ever made.”
She believes there are many reasons why it’s important for transgender people to have the option of playing sports on the team of their choice. “It provides a sense of community,” said O’Connor, now a first-year student concentrating in psychology at the College of DuPage in Glen Ellyn, Illinois.
“It’s a great way to get a workout, which is good for physical and mental health,” she added. She also enjoyed the opportunity to be competitive, learn about her strengths and weaknesses, and just be normal. “Trans people have friends and trans people want to play sports with their friends, especially in adolescence,” she said.
However, in 18 states, many of which are politically conservative, laws prohibit transgender students from participating in sports consistent with their gender identity, according to the Movement Advancement Project, an independent, nonprofit think tank based in Boulder, Colo., that focuses on the rights of LGBTQ people. The first ban was passed in Idaho in 2020, although federal district judges have halted this legislation and a similar law in West Virginia from taking effect.
Proponents of the bans caution that transgender females would have an unfair biological advantage in competitive school sports with other girls or women as a result of being born as stronger males, potentially usurping the athletic accomplishments of other athletes.
“The future of women’s sports is at risk, and the equal rights of female athletes is being infringed,” said Penny Nance, CEO and president of Concerned Women for America, a legislative action committee in D.C. that seeks to impact culture to promote religious values.
“As the tidal wave of gender activism consumes sports from the Olympics on down, a backlash is being felt as parents are furious about the disregard for their daughters who have worked very hard to achieve success as athletes,” Nance added. “Former athletes, whose records are being shattered, are demanding answers.”
Meanwhile, opponents of the bans contend that they bar transgender athletes from playing sports with friends and learning the value of teamwork and other life lessons. These laws target transgender girls most often in kindergarten through high school but sometimes in college as well. Many local schools and state athletic associations already have their own guidelines “to both protect transgender people and ensure a level playing field for all athletes,” according to the Movement Advancement Project’s website. But statewide bans take precedence over these policies.
"It’s easy to sympathize on some level with arguments on both sides, and it’s likely going to be impossible to make everyone happy,” said Liz Joy, a past president of the American College of Sports Medicine.
In January, the National Collegiate Athletic Association (NCAA), based in Indianapolis, tried to sort out the controversy by implementing a new policy. It requires transgender students participating in female sports to prove that they’ve been taking treatments to suppress testosterone for at least one year before competition, as well as demonstrating that their testosterone level is sufficiently low, depending on the sport, through a blood test.
Then, in August, the NCAA clarified that these athletes also must take another blood test six months after their season has started that shows their testosterone levels aren’t too high. Additional guidelines will take effect next August.
Even with these requirements, “there is no plan that is going to be considered equitable and fair to all,” said Bradley Anawalt, an endocrinologist at the University of Washington School of Medicine. Biologically, he noted, there is still some evidence that a transgender female who initiates hormone therapy with estrogen and drops her testosterone to very low levels may have some advantage over other females, based on characteristics such as hand and foot size, height and perhaps strength.
Liz Joy, a past president of the American College of Sports Medicine, agrees that allowing transgender athletes to compete on teams of their self-identifying gender poses challenges. “It’s easy to sympathize on some level with arguments on both sides, and it’s likely going to be impossible to make everyone happy,” said Joy, a physician and senior medical director of wellness and nutrition at Intermountain Healthcare in Salt Lake City, Utah. While advocating for inclusion, she added that “sport was incredibly important in my life. I just want everyone to be able to benefit from it.”
One solution may be to allow transgender youth to play sports in a way that aligns with their gender identity until a certain age and before an elite level. “There are minimal or no potential financial stakes for most youth sports before age 13 or 14, and you do not have a lot of separation in athlete performance between most boys and girls until about age 13,” said Anwalt, who was a reviewer of the Endocrine Society’s national guidelines on transgender care.
Myron Genel, a professor emeritus and former chief of pediatric endocrinology at Yale School of Medicine, said it’s difficult to argue that height gives transgender females an edge because in some sports tall women already dominate over their shorter counterparts.
He added that the decision to allow transgender females to compete with other girls or women could hinge on when athletes began taking testosterone blockers. “If the process of conversion from male to female has been undertaken in the early stages of puberty, from my perspective, they have very little unique advantage,” said Genel, who advised the International Olympic Committee (IOC), based in Switzerland, on testosterone limits for transgender athletes.
Because young athletes’ bodies are still developing, “the differences in natural abilities are so massive that they would overwhelm any advantage a transgender athlete might have,” said Thomas H. Murray, president emeritus of The Hastings Center, a pioneering bioethics research institute in Garrison, New York, and author of the book “Good Sport,” which focuses on the ethics and values in the Olympics and other competitions.
“There’s no good reason to limit the participation of transgender athletes in the sports where male athletes don’t have an advantage over women,” such as sailing, archery and shooting events, Murray said. “The burden of proof rests on those who want to restrict participation by transgender athletes. They must show that in this sport, at this level of competition, transgender athletes have a conspicuous advantage.”
Last year, the IOC issued a new framework emphasizing that the Olympic rules related to transgender participation should be specific to each sport. “This is an evolving topic and there has been—as it will continue to be—new research coming out and new developments informing our approach,” and there’s currently no consensus on how testosterone affects performance across all sports, an IOC spokesperson told Leaps.org.
Many of the new laws prohibiting transgender people from competing in sports consistent with their gender identity specifically apply to transgender females. Yet, some experts say the issue also affects transgender males, nonbinary and intersex athletes.
“There has been quite a bit of attention paid to transgender females and their participation in biological female sports and almost minimal focus on transgender male competition in male sports or in any sports,” said Katherine Drabiak, associate professor of public health law and medical ethics at University of South Florida in Tampa. In fact, “transgender men, because they were born female, would be at a disadvantage of having less lean body mass, less strength and less muscular area as a general category compared to a biological male.”
While discussing transgender students’ participation in sports, it’s important to call attention to the toll that anti-transgender legislation can take on these young people’s well-being, said Jonah DeChants, a research scientist at The Trevor Project, a suicide prevention and mental health organization for LGBTQ youth. Recent polling found that 85 percent of transgender and nonbinary youth said that debates around anti-transgender laws had a negative impact on their mental health.
“The reality is simple: Most transgender girls want to play sports for the same reasons as any student—to benefit their health, to have fun, and to build connection with friends,” DeChants said. According to a new peer-reviewed qualitative study by researchers at The Trevor Project, many trans girls who participated in sports experienced harassment and stigma based on their gender identity, which can contribute to poor mental health outcomes and suicide risk.
In addition to badminton, O'Connor played other sports such as volleyball, and she plans to become an assistant coach or manager of her old high school's badminton team.

However, DeChants added, research also shows that young people who reported living in an accepting community, had access to LGBTQ-affirming spaces, or had social support from family and friends reported significantly lower rates of attempting suicide in the past year. “We urge coaches, educators and school administrators to seek LGBTQ-cultural competency training, implement zero tolerance policies for anti-trans bullying, and create safe, affirming environments for all transgender students on and off the field,” DeChants said.
O’Connor said her experiences on the athletic scene have been mostly positive. The politics of her community lean somewhat liberal, and she thinks it’s probably more supportive than some other areas of the country, though she noted the local library has received threats for hosting LGBTQ events. In addition to badminton, she also played baseball, lacrosse, volleyball, basketball and hockey. In the spring, she plans to become an assistant coach or manager for the girls’ badminton team at her old high school.
“When I played badminton, I never got any direct backlash from any coaches, competitors or teammates,” she said. “I had a few other teammates that identified as trans or nonbinary, [and] nearly all of the people I ever interacted with were super pleasant and treated me like any other normal person.” She added that transgender athletes “have aspirations. We have wants and needs. We have dreams. And at the end of the day, we just want to live our lives and be happy like everyone else.”
With the population of older people projected to grow dramatically, and the cost of healthcare with it, the future welfare of the country may depend on solving aging, writes philosopher Ingemar Patrick Linden.
There is a lack of political will and leadership on the issue, and the idea that we should seek to do something about aging is generally met with a great deal of suspicion and trepidation. In a large representative study conducted by the Pew Research Center in 2013, only 38% of the respondents said that they would want a treatment that could slow the aging process and allow them to live at least 120 years. Apparently, most people prefer, or at least do not mind, to age and die within a natural lifespan. This result has been confirmed by smaller studies and it is, I think, surprising. Are we not supposed to live in a youth-culture? Are people not supposed to want to stay young and alive forever? Is self-preservation not the strong drive we have always assumed it to be?
We are inundated and saturated with an ideology of death-acceptance.
In my book, The Case against Death, I suggest that we have been culturally conditioned to think that it is virtuous to accept aging and death. We are taught to believe that although aging and death seem gruesome, they are what is best for us, all things considered. This is what we are supposed to think, and the majority accept it. I call this the Wise View because death acceptance has been the dominant view of philosophers since the beginning. Socrates compared our earthly life to an illness and a prison and described death as a healer and a liberator. The Buddha taught that life is suffering and that the way to escape suffering is to end the cycle of birth, death and rebirth. Stoic philosophers from Zeno to Marcus Aurelius believed that everything that happens in accordance with nature is good, and that therefore we should not only accept death but welcome it as an aspect of a perfect totality.
Epicureans agreed with these rival schools and famously argued that death cannot harm us because where we are, death is not, and where death is we are not. We cannot be harmed if we are not, so death is harmless. The simple view that death actually can harm us greatly is one of the least philosophical views one can hold.
In The Case Against Death, philosopher Ingemar Patrick Linden argues that we frown on using science to prolong healthy life only because we're culturally conditioned to think that way.
Many of the stories we tell promote the Wise View. One of the earliest known pieces of literature, the Epic of Gilgamesh, follows Gilgamesh on a quest for eternal life ending with the wisdom that death is the destiny of man. Today we learn about the tedium of immortality from the children’s book Tuck Everlasting by Natalie Babbitt, and we are warned about the vice of wanting to resist death in other books and films such as J.K Rowling’s Harry Potter, where Voldemort must kill Harry as a step towards his own immortality; C.S. Lewis’ The Chronicles of Narnia where the White Witch has gained immortal youth and madness in equal measures; J.R.R. Tolkien’s Lord of the Rings trilogy where the ring extends the wearer’s life but can also destroy them, as exemplified by the creep Gollum; and Doctor Strange where life extension is the one magical power that is taboo. In Star Wars, Yoda, a stereotype of the sage, teaches us the wisdom handed down by philosophers and prophets: “Death is a natural part of life. Rejoice for those around you who transform into the Force. Mourn them do not. Miss them do not.”
We are inundated and saturated with an ideology of death-acceptance. Can the dear reader name one single story where the hero is pursuing anti-aging, longevity or immortality and the villain tries to stop her?
The Wise View resonates with us partly because we think that there is nothing we can do about aging and death, so we do not want to wish for what we cannot have. Youth and immortality are sour grapes to us. Believing that death is, all things considered, not such a bad thing, protects us from experiencing our aging and approaching death as a gruesome tragedy. This need to escape the thought that we are heading towards a personal catastrophe explains why many are so quick to accept arguments against radical life extension, despite their often glaring weaknesses.
One of the most common objections to radical life extension is that aging and death are natural. The problem with this argument is that many things that are natural are very bad, such as cancer, and other things that are not natural are very good, such as a cure for cancer. Why are we so sure that cancer is bad? Because we assume that it is bad to die. Indeed, nothing is more natural than wanting to live. We seem to need philosophers and story tellers to talk us out of it and, in the words of a distinguished bioethicist, “instruct and somewhat moderate our lust for life.”
Another standard objection is that we need a deadline, and that without death we could postpone every action forever. “Death brings urgency and seriousness to life,” say proponents of this view, but there are several problems with this argument. Even if our lives were endless, there would still be many things we would have to do at a certain time, and that could not be redone, for example, saving our planet from being destroyed, or becoming the first person on Venus. And if we prefer pleasant endless lives over unpleasant endless ones, we will have to exercise, eat right, keep our word, develop our talents, show up for time at work, pay our taxes by the due date, remember birthdays, and so on.
The Wise View provides us with a feel-good bromide for the anxiety created by the foreknowledge of our decay and death by telling us that these are not evils, but blessings in disguise. Once perhaps an innocuous delusion, today the view stands in the way of a necessary societal commitment to research that can prolong our healthy life.
Besides, even if we succeeded in ending aging, we would still die from other causes. Given the rate of accidental deaths we would be fortunate to live to age 2000 all things equal. So even if, contrary to what I have argued, we do need a deadline, we can still argue that the natural lifespan that we now labor under is inhuman and that it forces each human to limit her ambitions and to become only a fragment of all that she that could have been. Our tight time constraint imposes tragic choices and inflated opportunity costs. Death does not make life matter; it makes time matter.
The perhaps most awful argument against radical life extension is grounded in a pessimism that holds life in such little regard that it says that best of all is never to have born. This view was expressed by Ecclesiastes in the Hebrew Bible, by Sophocles and several other ancient Greeks, by the German philosopher Arthur Schopenhauer, and recently by, among others, the South African philosopher David Benatar who argues that it is wrong to bring children into the world and that we should euthanize all sentient life. Pessimism, one suspects, largely appeals to some for reasons having to do with personal temperament, but insofar as it is built on factual beliefs, they can be addressed by providing a less negatively biased understanding of the world, by pointing out that curing aging would decrease the badness that they are so hypersensitive to, and by reminding them that if life really becomes unbearable, they are free to quit at any time. Other means of persuasion could include recommending sleep, exercise and taking long brisk walks in nature.
The Wise View provides us with a feel-good bromide for the anxiety created by the foreknowledge of our decay and death by telling us that these are not evils, but blessings in disguise. Once perhaps an innocuous delusion, today the view stands in the way of a necessary societal commitment to research that can prolong our healthy life. We need abandon it and openly admit that aging is a scourge that deserves to be fought with the combined energies equaling those expended on fighting COVID-19, Alzheimer’s disease, cancer, stroke and all the other illnesses for which aging is the greatest risk factor. The fight to end aging transcends ordinary political boundaries and is therefore the kind of grand unifying enterprise that could re-energize a society suffering from divisiveness and the sense of a lack of a common purpose. It is hard to imagine a more worthwhile cause.
A worker tends to a rural farm in Hanoi, Vietnam, where technology is making it easier to harvest an ancient fern called Azolla. Some scientists and farmers view Azolla as a solution to our modern-day agricultural and environmental challenges.
This “Arctic Azolla event” had devastating impacts on marine life. To date, scientists are trying to figure out how it ended. But they documented that the extraordinary event cooled down the Arctic by at least 40 degrees Fahrenheit — effectively freezing the poles and triggering several cycles of ice ages. “This carbon dioxide sequestration changed the climate from greenhouse to white house,” says Jonathan Bujak, a paleontologist who has researched the Arctic through expeditions since 1973.
Some farmers and scientists, such as Bujak, are looking to this ancient fern, which manipulated the Earth’s climate around 49 million years ago with its insatiable appetite for carbon dioxide, as a potential solution to our modern-day agricultural and environmental challenges. “There is no other plant like Azolla in the world,” says Bujak.
Decoding the Azolla plant
Azolla lives in symbiosis with a cyanobacterium called Anabaena that made the plant’s leaf cavities its permanent home at an early stage in Earth's history. This close relationship with Anabaena enables Azolla to accomplish a feat that is impossible for most plants: directly splitting dinitrogen molecules that make up 78 percent of the Earth’s atmosphere.
A dinitrogen molecule consists of two nitrogen atoms tightly locked together in one of the strongest bonds in nature. The semi-aquatic fern’s ability to split nitrogen, called nitrogen-fixing, made it a highly revered plant in East Asia. Rice farmers used Azolla as a biofertilizer since the 11th century in Vietnam and China.
For decades, scientists have attempted to decode Azolla’s evolution. Cell biologist Francisco Carrapico, who worked at the University of Lisbon, has analyzed this distinctive symbiosis since the 1980s. To his amazement, in 1991, he found that bacteria are the third partner of the Azolla-Anabaena symbiosis.
“Azolla and Anabaena cannot survive without each other. They have co-evolved for 80 million years, continuously exchanging their genetic material with each other,” says Bujak, co-author of The Azolla Story, which he published with his daughter, Alexandra Bujak, an environmental scientist. Three different levels of nitrogen fixation take place within the plant, as Anabaena draws down as much as 2,200 pounds of atmospheric nitrogen per acre annually.
“Using Azolla to mitigate climate change might sound a bit too simple. But that is not the case,” Bujak says. “At a microscopic level, extremely complicated biochemical reactions are constantly occurring inside the plant’s cells that machines or technology cannot replicate yet.”
In 2018, researchers based in the U.S. managed to sequence Azolla’s complete genome — which is four times larger than the human genome — through a crowdfunded study, further increasing our understanding of this plant. “Azolla is a superorganism that works efficiently as a natural biotechnology system that makes it capable of doubling in size within three to five days,” says Carrapico.
Making Azolla mainstream again in agriculture
While scientific groups in the Global North have been working towards unraveling the tiny fern’s inner workings, communities in the Global South are busy devising creative ways to return to their traditional agricultural roots by tapping into Azolla’s full potential.
Pham Gia Minh, an entrepreneur living in Hanoi, Vietnam, is one such citizen scientist who believes that Azolla could be a climate savior. More than two decades after working in finance and business development, Minh is now focusing on continuing his grandfather’s legacy, an agricultural scientist who conducted Azolla research until the 1950s. “Azolla is our family’s heritage,” says Minh.

Since the advent of chemical fertilizers in the early 1900s, farmers in Asia abandoned Azolla to save on time and labor costs. But rice farmers in the country went back to cultivating Azolla during the Vietnam War after chemical trade embargoes made chemical fertilizers far too expensive and inaccessible.
By 1973, Azolla cultivation in rice paddy fields was established on half a million hectares in Vietnam. By injecting nitrogen into the soil, Azolla improves soil fertility and also increases rice yields by at least 27 percent compared to urea. The plants can also reduce a farm’s methane emissions by 40 percent.
“Unfortunately, after 1985, chemical fertilizers became cheap and widely available in Vietnam again. So, farmers stopped growing Azolla because of the time-consuming and labor-intensive cultivation process,” says Minh.
Minh has invested in a rural farm where he is proving that modern technology can make the process less burdensome. He uses a pump and drying equipment for harvesting Azolla in a small pond, and he deploys a drone for spraying insecticides and fertilizers on the pond at regular intervals.
As Azolla lacks phosphorus, farmers in developing countries still find it challenging to let go of chemical fertilizers completely. Still, Minh and Bujak say that farmers can use Azolla instead of chemical fertilizers after mixing it with dung.
In the last few years, the fern’s popularity has been growing in other developing countries like India, Palestine, Indonesia, the Philippines, and Bangladesh, where local governments and citizens are trying to re-introduce Azolla integrated farming by growing the ferns in small ponds.
Replacing soybeans with Azolla
In Ecuador, Mariano Montano Armijos, a former chemical engineer, has worked with Azolla for more than 20 years. Since 2008, he has shared resources and information for growing Azolla with 3,000 farmers in Ecuador. The farmers use the harvested plants as a bio-fertilizer and feed for livestock.
“The farmers do not use urea anymore,” says Armijos. “This goes against the conventional agricultural practices of using huge amounts of synthetic nitrogen on a hectare of rice or corn fields.”
He insists that Azolla’s greatest strength is that it is a rich source of proteins, making it highly nutritious for human beings as well. After growing Azolla on a small scale in ponds, Armijos and his business partner, Ivan Noboa, are now building a facility for cultivating the ferns as a superfood on an industrial scale.
According to Armijos, one hectare of Azolla in Ecuador can produce seven tons of proteins. Whereas soybeans produce only one ton of protein per hectare. “If we switch to Azolla, it could help in reducing deforestation in the Amazon. But taming Azolla and turning it into a crop is not easy,” he adds.
Henriette Schluepmann, a molecular plant biologist at Utrecht University in the Netherlands, believes that Azolla could replace soybeans and chemical fertilizers someday — only if researchers can achieve yield stability in controlled environments over long durations.
“In a country like the Netherlands that is surrounded by water with high levels of phosphates, it makes sense to grow Azolla as a substitute for soybeans,” says Schluepmann. “For that to happen, we need massive investments to understand these ferns’ reproductive system and how to replicate that within aquaculture systems on a large scale.”
Pollution control and carbon sequestration
Currently, Schluepmann and her team are growing Azolla in a plant nursery or closed system before transferring the ferns to flooded fields. So far, they have been able to continuously grow Azolla without any major setbacks for a total of 155 days. Taking care of these plants’ well-being is an uphill struggle.
Unlike most plants, Azolla does not grow from seeds because it contains female and male spores that tend to split instead of reproducing. To add to that, growing Azolla on a large scale in controlled environments makes the floating plants extremely vulnerable to insect infestations and fungi attacks.
“Even though it is easier to grow Azolla on a non-industrial scale, the long and tedious cultivation process is often in conflict with human rights,” she says. Farms in developing countries such as Indonesia sometimes use child labor for cultivating Azolla.”
History has taught us that the uncontrolled growth of Azolla plants deprives marine ecosystems of sunlight and chokes life underneath them. But researchers like Schluepmann and Bujak are optimistic that even on a much smaller scale, Azolla can put up a fight against human-driven climate change.
Schluepmann discovered an insecticide that can control Azolla blooms. But in the wild, this aquatic fern grows relentlessly in polluted rivers and lakes and has gained a notorious reputation as an invasive weed. Countries like Portugal and the UK banned Azolla after experiencing severe blooms in rivers that snuffed out local marine life.
“Azolla has been misunderstood as a nuisance. But in reality, it is highly beneficial for purifying water,” says Bujak. Through a process called phytoremediation, Azolla locks up pollutants like excess nitrogen and phosphorus and stops toxic algal blooms from occurring in rivers and lakes.
A 2018 study found that Azolla can decrease nitrogen and phosphorus levels in wastewater by 33 percent and 40.5 percent, respectively. While harmful algae like phytoplankton produce toxins and release noxious gases, Azolla automatically blocks any toxins that its cyanobacteria, Anabaena, might produce.
“In our labs, we observed that Azolla works effectively in treating wastewater,” explains Schluepmann. “Once we gain a better understanding of Azolla aquaculture, we can also use it for carbon capture and storage. But in Europe, we would have to use the entire Baltic Sea to make a difference.”
Planting massive amounts of these prehistoric ferns in any of the Northern great water bodies is out of the question. After all, history has taught us that the uncontrolled growth of Azolla plants deprives marine ecosystems of sunlight and chokes life underneath them. But researchers like Schluepmann and Bujak are optimistic that even on a much smaller scale, Azolla can put up a fight against human-driven climate change.
Traditional carbon capture and storage methods are not only expensive but also inefficient and could increase air pollution. According to Bujak’s estimates, Azolla can sequester 10 metric tonnes of carbon dioxide per hectare annually, which is 10 times the average capacity of grasslands.
“Anyone can set up their own DIY carbon capture and storage system by growing Azolla in shallow water. After harvesting and compressing the plants, carbon dioxide gets stored permanently,” says Bujak.
He envisions scaling up this process by setting up “Azolla hubs” in mega-cities where the plants are grown in shallow trays stacked on top of each other with vertical farming systems built within multi-story buildings. The compressed Azolla plants can then be converted into a biofuel, fertilizer, livestock feed, or biochar for sequestering carbon dioxide.
“Using Azolla to mitigate climate change might sound a bit too simple. But that is not the case,” Bujak adds. “At a microscopic level, extremely complicated biochemical reactions are constantly occurring inside the plant’s cells that machines or technology cannot replicate yet.”
Through Azolla, scientists hope to work with nature by tapping into four billion years of evolution.
