Leaf Blowers Suck. Here’s Why.

As I sit writing this, I’m surrounded by the sounds of fall. The gentle whisper of the Autumnal wind, the ominous cawing of crows, and the incessant drone of leaf blowers emanating from at least three adjacent properties. Sure, leaf blowers might be among the most irritating inventions ever created by man, but could we really go so far as arguing that it’s morally wrong to use them? I’m certainly willing to try.

One common starting point for assessing the morality of an action is to ask whether the benefits of that action outweigh its costs. There are, of course, benefits to using a leaf blower. For one, they help homeowners maintain the appearance of their properties. And there’s a lot of fun to be had in wielding a loud, powerful piece of machinery. But there are also costs.

First up, they’re a neighborly nuisance – and not just because of the noise pollution they create. The blasts of air generated by leaf blowers are greater than those found in a Category 5 hurricane, and, as such, are able to kick up large amounts of particulate matter (about 5 pounds per hour). According to the Department of Environmental Conservation, this matter often includes pollen, mold, animal faeces, heavy metals, and chemicals from herbicides and pesticides. This matter can take many hours to settle, traveling surprisingly large distances and blanketing surrounding homes in the process.

But the environmental cost of leaf blowers goes even further than this. Due to the terrible fuel efficiency of their two-stroke engines, thirty minutes of using a consumer-grade leaf blower will result in roughly the same amount of carbon emissions as driving a Ford F-150 from Texas to Alaska. In fact, in California, gas-powered leaf blowers are now a larger source of smog-forming emissions than the state’s 14.4 million passenger vehicles. But while vehicles (arguably) serve an essential purpose, leaf blowers are a mere frivolity. All of this has resulted in an outright ban on leaf blowers in a number of cities in California, Colorado, Illinois, Massachusetts, New Jersey, New York, Texas, and Vermont.

But what does this mean for the rest of us? Should we return to those pre-leaf blower days and pick up our trusty rakes instead? Not necessarily. Removing leaves entirely from your yard – even with a rake – may still do more harm than good. According to the Environmental Protection Agency, more than 10 million tonnes of yard debris went into landfills in 2018 (the last year for which data is available). When this debris breaks down in the anaerobic (that is, zero-oxygen) environment of a landfill it creates methane – a greenhouse gas that’s twenty-five times worse than carbon dioxide. If, on the other hand, those leaves are left on your property, they can do a world of good for your garden. They provide a vital habitat for all kinds of creatures including butterflies, salamanders, insects, chipmunks, toads, earthworms, and even box turtles. Despite the obvious value in preserving biodiversity, many of these creatures also make up a highly beneficial (if not vital) part of a garden’s biome. If the desire to clean up those leaves is overwhelming, then there are better ways of doing this too. Mulching or composting leaves on-site allows for this debris to break down in an aerobic (that is, oxygen-rich) environment, avoiding the production of methane. This also allows for nutrients to be cycled back into the ground, minimizing the need to purchase expensive fertilizers.

It’s important to note that, while the focus here has so far been on leaf blowing, many of the same arguments also apply to our obsession with lawn maintenance more generally. A large portion of that 10 million tonnes of lawn debris mentioned above is merely lawn clippings. Further, like leaf blowers, lawn mowers also come with an enormous carbon cost.

Close-cut grass lawns first emerged in 17th-century England as a mark of wealth and status. Traditionally, landowners sought to squeeze as much productivity out of their properties as possible by dedicating every last square foot to crops or grazing pasture. The rich, however, had such affluence that they could devote large tracts of land to an entirely wasteful endeavor – the growing of a lawn. While the original purpose behind lawns might have been forgotten, its largely wasteful nature remains. There’s an estimated 40-50 million acres of lawn in the continental United States – almost as much as all of the country’s national parks combined. In 2020, Americans spent $105 billion dollars maintaining those lawns, and consumed 3 trillion gallons of water, 59 million pounds of pesticide, and 3 billion gallons of gasoline (the equivalent of around 6 million passenger cars running for a year) in the process. All of this to merely sustain what entomologist Doug Tallamy describes as an ecologically “dead space.”

Law maintenance – like leaf blowing – does far more harm than good. What’s worse, it’s unnecessary harm. There are many alternatives to the traditional lawn that come with lower waste, lower carbon emissions, and lower maintenance costs. So throw out your leaf blower and ditch that patch of wasteful sod in favor of something else. The environment – and your wallet – will thank you for it.

The Amazon Fires: Responsibility, Obligation, and the Limitations of the State

President Jair Bolsonaro of Brazil refused to accept proposed aid from members of the G7 for the Amazon fires, in part because of a personal feud with President Emmanuel Macron of France about the respective leaders’ wives. Yet the Amazon rainforest continues to burn. Another concern of the Brazilian government is the implication that accepting foreign aid has for the country’s sovereignty. President Bolsonaro alleged that the French president “disguises his intentions behind the idea of an ‘alliance’ of the G7 countries to ‘save’ the Amazon, as if we were a colony or a no-man’s land.” But should President Bolsonaro’s refusal for aid continue and the burning of the Amazon continue, what is the next step? Who, if anyone, has an obligation to put out the fires? When is it justified to defy national sovereignty?

To violate a country’s sovereignty is a dramatic move; the cause would have to be of great importance. In 1999, the then-UN Secretary-General Kofi Annan defined the modern state as “instruments at the service of their people.” Failure of the state to deliver services to its people would warrant external aid. The UN Charter states that member states should refrain from “the threat or use of force against the territorial integrity or political independence of any state, or in any other manner inconsistent with the Purposes of the United Nations.” 

But the definition of the modern state and Purposes of the UN speak only to human concerns; nowhere is there an acknowledgement of environmental concerns. Even though conventions have been devised, the impasse regarding aid for the fires reveals a hole in the recommendations of international organizations. Even the recommendations about natural disasters do not apply given that the fires were apparently ignited by farmers clearing land for agriculture.

While the United Nations is not an authority on ethics in international relations, its charter is a useful touchstone given that its prescriptions often advise the international community’s response to global events. The burning of the Amazon, however, presents a non-standard case. Violating national sovereignty is often justified by protecting the lives of humans. But how should the international community respond to threats to non-human life?

Celebrities, NGOs, and political leaders alike have called the Amazon “the lungs of the world” given the amount of oxygen it produces. For that reason alone, it would appear that this fire is directly affecting the livelihood of humanity; thus, falling under the umbrella of justifications of acceptable international intervention. But some individuals have cast doubt on the claims about the rainforest’s contribution to the planet’s oxygen. 

“The Amazon produces about 6 percent of the oxygen currently being made by photosynthetic organisms alive on the planet today,” writes Peter Brannen. “[F]rom a broader Earth-system perspective, in which the biosphere not only creates but also consumes free oxygen, the Amazon’s contribution to our planet’s unusual abundance of the stuff is more or less zero.” Speaking to Forbes, Dr. Dan Nepstad of the Earth Innovation Institute called the popular descriptor of lungs “bullshit”, saying that the Amazon uses as much oxygen as it produces through respiration. The significance of the photosynthetic production of air and the Amazon’s instrumental value may be exaggerated. 

Even so, the Amazon basin contains incredible biodiversity, housing a staggering 10% of the known species on Earth despite occupying only 1% of the planet’s surface area. The rainforest is the largest of its kind in the world. The river that slices through the rainforest is the longest in the world. By any measure, the Amazon is a natural wonder, irrespective of its relationship with humans. And some argue that it possesses its own intrinsic value. 

Writing on one view of the intrinsic value of nature, Professor Ronald Sandler states: “[N]atural entities, including species and some ecosystems, have intrinsic value in virtue of their independence from human design and control and their connection to human-independent evolutionary processes.” Proponents of this view would argue that the Amazon ought to be protected not because of its value to us–be that in the form of oxygen or bewonderment–but because it has value without us.

Suppose then that the Amazon has intrinsic value and is, thus, worthy of protecting: is anyone obligated to protect it when the government in which it is in is failing to do so? Some may reference the dictum that those with the means to help are obligated to help. But the ethical expectations for individuals may not seamlessly apply to the ethical obligations of organizations. The discussion becomes more complex when considering non-state actors, such as NGOs, which do not operate under the same responsibilities.

NGOs whose cause it is to protect and encourage the biodiversity of different natural environments may see the perceived inaction of the Brazilian government as moral permission to intervene and provide aid. In some cases, non-governmental intervention occurs without any controversy, such as when an NGO delivers assistance to a developing country that is unable to provide clean water to its people. These organizations are likely in a better position to avoid the claims of sovereignty violation that have hampered the acceptance of foreign state aid simply because they are not pursuing a national state agenda. 

Yet while NGOs are able to help, there are some disadvantages to having them do so. They lack the democratic accountability of a state actor; they are not responsible for anything but pursuing their cause. Because of that they could feasibly maintain a presence in the country past the point that it is necessary and undermine the government’s ability to act. 

States, however, do not suffer from the same disadvantages and are constrained by international norms.  But if they are indeed “instruments at the service of their people,” states would appear to be obligated only to serving their people. It is not clear that states have the obligation to intervene in the destruction of a natural environment in another country. Furthermore, it is not clear if it would even be permissible to do so. International agreement on the notion that nature has intrinsic value may prove elusive, leaving the question of who should put out the fires unanswered, even if everyone agrees the fires should be put out. Perhaps the burning of the Amazon illustrates the growing obsolescence of our modern definition of the state.

Power, Pollution, and Golf

Despite the closure of over 800 golf courses in the last decade and the fact that young people have virtually no interest in the sport, golf may be the emblematic pastime of the 21st century. So many of the key issues our society must grapple with in the next hundred years or so, from environmental change to the concentration of wealth and political power in the hands of an elite few, are borne witness to on the vast stretches of meticulously maintained green. Given the ethical ramifications of those issues, it’s pertinent to ask whether or not the continuation of the sport of golf itself is ethical, and what the prevalence of this sport might say about our future.

The first and most pressing objection to golf is its environmental impact. Apart from impact of pesticides, environmental scholars note that “Golf course maintenance can also deplete fresh water resources [… and] require an enormous amount of water every day,” which can lead to water scarcity. A golf course can take up nearly 150 acres of land and can displace the area’s native flora and fauna in favor of an artificial and homogenized landscape. Furthermore, the impact of a golf course can be felt beyond the land it physically occupies. From 2017 to 2019, a teenage diver found over 50,000 golf balls underwater off the coast of California, the byproduct of five nearby golf courses. This is especially concerning to environmentalists, because, as the NPR reporter who covered the story noted, “golf balls are coated with a thin polyurethane shell that degrades over time. They also contain zinc compounds that are toxic.” They eventually break down into microplastics, an especially insidious form of pollution.

However, some argue that golf courses enclose and protect rather than damage fragile ecosystems. One such often-referenced paper, “The Role of Golf Courses in Biodiversity Conservation and Ecosystem Management,” was written by Johan Colding and Carl Folke and published in 2009. After examining the effect of golf courses on local insect and bird populations, Colding and Folke concluded that “golf courses had higher ecological value relative to other green-area habitats,” and “play essential role in biodiversity conservation and ecosystem management.” They argue that golf courses can be a refuge for wildlife that’s been pushed out from other areas, and that golf courses can foster biodiversity by working hand-in-hand with conservationists. However, this paper was published by Springer Science+Business Media, a global publishing company of peer-reviewed scientific literature that had to retract 64 scientific papers in 2015 after it was discovered that the articles hadn’t actually been peer reviewed at all. Seen in that light, this research (and the conclusion it draws) becomes questionable. Another study, “Do Ponds on Golf Courses Provide Suitable Habitat for Wetland-Dependent Animals in Suburban Areas? An Assessment of Turtle Abundances, published in The Journal of Herpetology in 2013, examined the potential for golf courses to contain turtle habitats with mixed results. The researchers noted that turtle habitats within golf courses did have the potential to foster wildlife, but were negatively impacted by residential development projects, which many golf courses today contain. To summarize, there is no clear consensus on this issue, though researchers uniformly note the very act of building a golf course in the first place does disrupt wildlife, whether or not conservation efforts are made after the fact.

Golf may have an ultimately negative impact on the environment, but its continuance has ethical implications for our social and political landscape as well. Golf has long been considered an elite pastime, and President Trump’s fondness for the sport is often used to demonstrate his insufficiencies as a leader. Rick Reilly, a contributing writer for ESPN’s SportsCenter and ABC Sports, released a book in early April of this year entitled Commander in Cheat: How Golf Explains Trump. In an article for The Atlantic explaining how Trump has sullied the reputation of golf through his propensity to cheat and tasteless displays of wealth, Reilly laments,

“[The situation] stinks because we were finally getting somewhere with golf. It used to be an elitist game, until the 1960s, when a public-school hunk named Arnold Palmer brought it to the mailmen and the manicurists. Then an Army vet’s kid named Tiger Woods brought it to people of color all over the world. We had ultracool golfers like Woods, Rickie Fowler, and Rory McIlroy, and pants that don’t look like somebody shot your couch, and we’d gotten the average round of golf down to $35, according to the National Golf Foundation.”

However, it’s difficult to stand by Reilly’s assertion that golf has entirely outgrown its elitist roots. In an interview with Golf Digest, Trump remarked,

“First of all, golf should be an aspirational game. And I think that bringing golf down to the lowest common denominator by trying to make courses ugly because they want to save water, in a state that has more water […]

I would make golf aspirational, instead of trying to bring everybody into golf, people that are never gonna be able to be there anyway. You know, they’re working so hard to make golf, as they say, a game of the people. And I think golf should be a game that the people want to aspire to through success.”

Replace the word “golf” with “power,” and you’ve got an almost eerily succinct and transparent summary of capitalist conservative dogma (in which the playing field is never intended to be even, the environment is devalued in favor of aesthetics, and the American dream is only illusory for the masses). But furthermore, Trump’s comment encapsulates many of the elitist attitudes and expectations that still attend golf today, regardless of the price for a single round at a public course. The resorts and country clubs frequented by Trump and his ilk are beautifully manicured arenas of power, places where politicians and businessmen can solidify ties and network over club sodas. When he was attacked for misogynistic remarks about women, Trump’s defense was that he’d heard Bill Clinton say worse things about women on the golf course, going so far as to call Mar-a-Lago, the resort attached to a golf course owned and frequented by Trump, the “The Southern White House.” The words “golf course” have become shorthand for private spaces of leisure for powerful men, a place for unethical behavior sheltered from the public eye and more traditional structures of power by miles of dense greenery.

Unlike sports that are not as white or monolithic, like basketball and football, contemporary golf is not fertile ground for political or cultural resistance. Golfers are notably non-vocal about politics. As golf correspondent Lawrence Donegan points out, many famous pro-golfers are pressured to play golf with the president, and show almost uniform deference to him out of fear of losing corporate sponsorships. This deferential attitude is taken up by most elites who play golf. Donegan says,

“The acquiescence of golf’s leading figures and governing bodies [to the Trump administration] is amplified […] down the sport’s hierarchy, especially in the (sometimes literally) gilded country clubs of states such as Florida, New Jersey, New York, and Texas, which depend on a narrow, and narrow-minded, membership of wealthy, white couples who pay their subscriptions as much for the social cachet as for the sport. Within the confines of the club, they are free to rail against minorities, free to declare Trump the greatest president since Lincoln, free to act like the genteel segregationists they prefer to be.”

The fact is that golfers tend to be wealthy, and that the golf course is a place where hierarchy and prestige are not only respected but built into the very foundation of the culture.

Many agree that golf is both a waste of resources and a symbol for the mechanisms of capitalism, but these two issues have become intertwined in recent years. Golf, some have argued, has been yoked in the service of capitalism and corporate “greenwashing.” Rob Millington explores this idea in his paper “Ecological Modernization and the Olympics: The Case of Golf and Rio’s ‘Green’ Games,” published in the Sociology of Sport Journal in 2018. He defines ecological modernization as “the idea that capitalist-driven scientific and technological advancements can not only attend to the world’s pending environmental crises, but even lead to ecological improvement, thus allowing sustainability and consumption to continue in concert.” This idea is promoted by corporations who want to greenwash themselves, or to appear green to consumers without changing their essential business models. It is very similar to the conclusion drawn by Colding and Folke, who argue that environmental destruction in the name of leisure and consumerism can take place alongside conservationist efforts without contradiction.

Millington notes that “In response to the growing tide of environmental opposition since the 1960s, the golf industry took up an ecological modernist approach to promote golf as a natural, green, and environmentally friendly sport that allows people to connect with nature.” According to Millington, this is precisely what happened in 2016 Olympic games at Rio De Janeiro, for which a golf course was built on environmentally protected land in the spirit of ecological modernization. The design of the course was presented as enhancing rather than fighting the natural landscape, despite the fact that any incursion into a natural space can disrupt the ecosystem. In this sense, the continuing relevance of golf can be employed for neoliberal ends, under the guise of environmentalism or unity between nations.

In “Is Golf Unethical?”, a 2009 article published in The New York Times, writer Randy Cohen covers the basic environmental impact and bourgeois ethos of golf. On the question of whether or not the sport itself is ethical, he concludes that “perhaps the only moments of grace and beauty and virtue in any game occur during actual play, and we should not look too closely at its broader culture and implicit ethics without expecting to be dismayed.” This is just one defense of the sport, that the skill that goes into mastering it outweighs any moral scruples we should have. Another thing often said in defense of golf is that it, like any sport, builds bridges and creates a sense of fellowship across the world, that it gives us a common language in which to communicate our values and abilities across international lines. But does it actually build bridges between nations or just import elite bourgeois culture and sources of pollution to other parts of the world? The act of swinging a golf club has no objective moral value attached to it, but the trappings of golf, the privilege and waste and unnecessary consumption of resources, certainly do.  

The Indianapolis Prize and the Ethics of Conservation

Photograph of a lemur turning toward the camera over its puffy tail

On Saturday, September 29, the Indianapolis Zoological Society hosted its biennial awards ceremony, the Indianapolis Prize Gala, at the JW Marriot hotel in Indianapolis, Indiana. Referred to as “the Nobel Prize of animal conservation,” the Indianapolis Prize is awarded every second year to a scientist deemed to have contributed significantly to wildlife conservation. This year, Dr. Russ Mittermeier received the honor, which includes a $250,000 award, for his work with various primate species over a 45-year career. The gala also recognizes a celebrity who has advanced the cause of conservation through funding, visibility, and outreach: this year, actor Harrison Ford was the recipient of that honor. In his speech, Ford said, “Protecting nature is first and foremost for me a moral imperative.” Inspiring as that statement may be, it remains to be seen exactly what kind of moral imperative there is regarding nature. What is the most ethical way to support and protect the environment? Furthermore, what kind of relationship should human beings maintain with our environment?

Bullfighting: Moral Good or Unnecessary Cruelty?

An image of a bull dying in a bullfight.

Bullfighting has always been controversial in the Spanish-speaking world. Strangely, most of the intellectual defenders of this ancient tradition have not been Hispanic themselves. In the twentieth century, the staunchest defender of bullfighting was Ernest Hemingway, an American. Yet, Hemingway was not a philosopher, and his defense of bullfighting relied more on emotion than on reason. The staunchest intellectual defender of bullfighting in the 21st century is a Frenchman, Francis Wolff. Unlike Hemingway, Wolff is a philosopher, and in a series of books and articles, he has attempted to make a philosophical defense of bullfighting, based on reasoned ethical arguments. Although these arguments are sometimes ingenious, they are for the most part flawed.

Economics and Sustainability in the Overfishing of Bluefin Tuna

A recent auction of bluefin tuna at the Tsukiji market in Tokyo sparked recurring discussions over the environmental and economic effects that overfishing and big tuna businesses are putting on local areas and fisheries. This came as a 212-kilogram fish sold at Tsukiji for 74.2 million yen (or the equivalent $64,200), which per piece would cost over 25 times the 400 yen usually charged at the bidder’s restaurants.
