Is the sharing economy really green?

sharing1So many assumptions underly conventional wisdom about all things green. That biofuels are better for the planet than burning fossil fuels. That bans on plastic bags help the environment. That electric cars reduce CO2 emissions. That eating meat is bad for the climate.

All these things are true, I believe. But what I believe doesn’t matter. The question is, where’s the evidence? On biofuels, plastic bags and electric cars, the environmental impacts depend on where the crops to make biofuels are grown, what replaces plastic bags, the electricity mix that powers the electric car and how the cows that went into your burger were raised.

The point is, the “environment” is an extraordinarily complex system, as is the economy. That’s the underlying message of a story that I wrote last week for the environmental website Ensia headlined Is Sharing Really Green?

Here’s how it begins:

I’m a big fan of the sharing economy. On a recent trip to San Francisco, I stayed in a house I found onAirbnb and made my way around the city using uberX. I’ve written favorably about house sharingcar sharingbike sharingand getting rid of stuff you no longer want via yerdle. At environmental conferences, I’ve listened to evangelists for the sharing economy such as Lisa GanskyRobin Chase and Andy Ruben. Participating in the sharing economy can save money, open people up to new experiences and build a sense of community among strangers.

But I’m not convinced the sharing economy delivers the environmental benefits its proponents claim.

Because the sharing economy enables more efficient use of underutilized assets — a car that might otherwise sit in a driveway, an extra room in a home, an electric drill or even a wedding dress — conventional wisdom holds that the sharing economy is “green.” With a little help from Google, it’s easy to find headlines like “How Web Sharing Sites Can Save the Planet” and “The Sharing Economy for a Sustainable Future.” Graham Hill, the founder of Treehugger and LifeEdited, has said the sharing economy “makes a lot of sense financially and environmentally as well.” In her book, The Mesh: Why the Future of Business Is Sharing, entrepreneur and investor Lisa Gansky writes: “Using sophisticated information systems, the Mesh [her term for the sharing economy] also deploys physical assets more efficiently. That boosts the bottom line, with the added advantage of lowering pressure on natural resources.” In an interview with Treehugger, Roo Rogers, co-author with Rachel Botsman of a book called What’s Mine is Yours: The Rise of Collaborative Consumption, declared: “In my opinion — having been an environmentalist all my life — collaborative consumption has the potential to have the biggest environmental impact that we could ever have hoped for.”

But where’s the evidence? It’s hard to find.

I probably could have written that the evidence is non-existent, but the sharing economy is so new and so hard to measure that it’s no surprise that the case for its “green” benefits remains unproven.

I hasten to add that there are still good reasons to patronize Airbnb or Zipcar or Rent the Runway or the many other sharing sites that seem to be proliferating. There’s little harm done when we make personal choices based on our assumptions about what’s good for the planet.

But when big companies or, worse, governments set policy without questioning their assumptions, the consequences can be negative on a much broader scale. I’m afraid that happens a lot more often than it should.

Paul Greenberg’s fish stories

AmericanCatchCoverMuch of what I know about seafood I’ve learned from Paul Greenberg. Paul is an acquaintance and a gifted writer whose new book, called American Catch: The Fight for Our Local Seafood, looks at three iconic American seafood species: New York oysters, Gulf shrimp and Alaska salmon. It’s a sequel of sorts to his previous book, Four Fish: The Future of the Last Wild Food, which I blogged about in 2010.

In the introduction to the new book, Paul describes the impact of globalization on the seafood that we catch and eat in the US:

By all rights this most healthy of food should be an American mainstay. The United States controls more ocean than any other country on earth. Our seafood-producing territory covers 2.8bn acres, more than twice as much real estate as we have set aside for landfood.

But in spite of our billions of acres of ocean, our 94,000 miles of coast, our 3.5m miles of rivers, a full 91% of the seafood Americans eat comes from abroad.

..It gets fishier still. While 91% of the seafood Americans eat is foreign, a third of the seafood that Americans catch gets sold to foreigners. By and large the fish and shellfish we are sending abroad are wild while the seafood we are importing is very often farmed.

…American consumers suffer from a deficit of American fish, but someone out there somewhere is eating our lunch.

Last week, I interviewed Paul by email for Guardian Sustainable Business. I asked him why trade in seafood differs from the global exchange of other goods, the prospects for restoring oysters to New York harbor and a couple of intriguing experiments with community-supported fisheries. You can read his responses here.

There’s encouraging news in Paul’s fish stories. Alaska’s salmon fishermen are in the midst of what could be a successful effort to protect the world’s most productive salmon fishery from Pebble Mine a massive gold and copper mine near Bristol Bay. (The EPA moved to block the mine last week.) Meantime, nonprofit groups in New York are laboring to bring back the oysters that were once plentiful up and down the east coast.

A lifelong fisherman, Paul brings to these stories and obvious passion for his subject and a zest for adventure. (He uncovers and consumes a New York oyster from the muddy waters of the East River.) More than passion, though, goes into a book like American Catch. In the acknowledgements, I learned that Paul’s editor put him through seven drafts of the manuscript. The result, a rarity in this world of 24-7 news, instant analysis, and blogging on the run, is a work of journalism that delivers both insight and enormous pleasure.

The upside of outsourcing

To match Insight INDIA-OUTSOURCING/I heard an excellent, in-depth interview this week with William Easterly, the development economist and author of a new book called The Tyranny of Experts: Economists, Dictators and the Forgotten Rights of the Poor. Easterly, a controversial figure, is critical of top-down development experts — he names Jeffrey Sachs and Bill Gates, among others — who push technocratic, centralized approaches to alleviating poverty. Instead, he argues that the best way to promote economic development is for westerners to push for democracy, human rights and free markets in the world’s poorest countries.

Easterly cites, among others, the Nobel laureate Amartya Sen, who has said: “No famine has ever taken place in the history of the world in a functioning democracy.” Others disagree, noting that parts of India came perilously close to famine just a decade ago. What’s more, China has lifted hundreds of millions of people out of poverty while suppressing human rights, but allowing economic freedom.

I’m in no position to try to adjudicate the debate about how poor countries become rich, but I was thinking about Easterly’s faith in markets and global trade as I wrote my story this week for Guardian Sustainable Business. The story looks at an idea called “socially-responsible outsourcing” or simple “impact sourcing,” and a nonprofit called DDD that tries to put that idea into practice. (DDD stands for Digital Divide Data.) DDD operates businesses in Cambodia, Kenya and Laos that employ young people, typically high school age, to provide information technology and web research, mostly to clients in the US. The goal of the enterprise is to provide economic opportunity to the poor, DDD’s founders told me.

Here’s how my story begins:

So much attention is paid to deplorable factory conditions in poor countries that it’s easy to forget that global supply chains for electronics, apparel and toys have helped lift masses of people out of poverty. Since 1980, 680 million people have risen out of poverty in China which has seen its extreme-poverty rate fall from 84% to about 10%, largely because of trade, reports The Economist.

Now, a small number of companies, nonprofits and foundations want to see if the rapidly growing global supply chains that process data and operate call centers — an industry usually described as business processing outsourcing, or BPO — can be deployed to help alleviate poverty in Africa and South Asia. Can outsourcing, a business driven by the search for cheap labor, reconfigure itself to do good?

“By responsibly and ethically employing hundreds of thousands of people, BPOs have a role to play in shifting the social landscape in emerging economies around the world,” says a report called Outsourcing for Social Good from Telus International, a Canadian outsourcing firm, and Impakt, a social responsibility consultancy.

Others agree. The Rockefeller Foundation has committed $100m to a project called Digital Jobs Africa that aims to improve one million lives in six African nations. A nonprofit called Samasource organizes poor women and youth in Africa and Asia to deliver data services to such businesses as Microsoft and Google. And a company called Cloud Factory that operates in Kenya and Nepal says digital outsourcing can “flatten the world, connect people into the global economy and raise up leaders to fight poverty and change their communities.”

The pioneer of what is called socially-responsible outsourcing or simply impact sourcing is DDD (Digital Divide Data), a New York-based nonprofit that operates for-profit data centers in Cambodia, Laos and Kenya. DDD and its impact-oriented peers set themselves apart from outsourcing giants such as Tata, Accenture and Infosys because, they says, they deliberately seeks out workers in the some of the world’s poorest places and provides them not just with jobs, but with the education, training and career counseling they need to rise into the middle class.

“Our ultimate mission is to alleviate poverty,” says Jeremy Hockenstein, 42, the founder and CEO of DDD. “We focus on students who are finishing high school, who are very motivated and very smart and who come from low-income homes.”

Having met Jeremy Hockenstein (via Skype) and his co-founder Michael Chertok (face to face), I have no doubt of their good intentions. Both gave up more lucrative careers to start the nonprofit. DDD is about helping its global employees, not exploiting them.

But their work raises an intriguing question about how much intentions matter when it comes to infotech outsourcing, or all of global trade, for that matter. Despite all the the abuses in the global manufacturing supply chain, it seems inarguable that the factory jobs created in China, Mexico, India and Bangladesh have benefited the poor in those countries. Is it possible the Walmart and Apple have done more to alleviate poverty than Bill Gates and Jeffrey Sachs?

The elusive fortune at the base of the pyramid

cimg7634It’s been an exceptionally busy week, beginning with the 2014 edition of Fortune Brainstorm Green (selected videos are online here) and ending with a holiday weekend visit from my new grandson, so I’m going to quickly post a link to my latest story for Guardian Sustainable Business.

It’s a long-ish story about doing business at the bottom of the pyramid, an idea popularized by the late C.K. Prahalad in a book published a decade ago. Here’s how the story begins:

When CK Prahalad‘s book, The Fortune at the Bottom of the Pyramid, was published in 2004, the book made an immediate splash. Its argument was irresistible: The world’s poorest people are a vast, fast-growing market with untapped buying power, Prahalad wrote, and companies that learn to serve them can make money and help people escape poverty, too.

Microsoft founder Bill Gates called the book “an intriguing blueprint for how to fight poverty with profitability”. BusinessWeek’s Pete Engardio described Prahalad, a professor at the University of Michigan business school, as a business prophet. He was awarded honorary degrees and sought out by CEOs.

Ten years later, businesses big and small continue to pursue profits at the bottom of the pyramid. The global uptake of mobile phones has proven that poor people will buy cell service if it’s available at low prices. (It costs a fraction of a cent per minute in India.) Single-serve packages of shampoo, toothpaste and soap dangle from shelves of tiny storefronts in rural villages. Products ranging from eyeglasses to solar panels are being designed and marketed to people earning $2 a day.

The bottom-of-the-pyramid (BOP) market leader, arguably, is Unilever, with its Anglo-Dutch colonial heritage and a chief executive, Paul Polman, who is determined to improve the world. Unilever generates more than half of its sales from developing markets, with much of that coming from the emerging middle class. Its signature BOP product is Pureit, a countertop water-purification system sold in India, Africa and Latin America. It’s saving lives, but it’s not making money for shareholders.

And there’s the rub. If there is a fortune to be made at the bottom of the pyramid, it remains elusive. Partly that’s because doing business with the poor is unavoidably complex, and partly that’s because the notion was oversold, says Mark Milstein, director of the Center for Sustainable Global Enterprise at Cornell’s business school and an expert on the BOP.

“I haven’t seen anyone making a fortune,” Milstein told me. “Unilever’s made money on some products, but they’ve been challenged. Other companies are making profits, but not enough to matter to their organization.”

The story goes on to report on successful and not-so-successful efforts to do business with the world’s billion or two poor people. We’ll be considering this topic again next month at the Guardian, with a live tweet chat on Tuesday, June 10, at noon. You can read the rest of my story here.

Biz Stone: A good guy who’s doing very well

Biz Stone, co-founder of Twitter, speaks at the Charles Schwab IMPACT 2010 conference in BostonI’m a big fan of Twitter. It’s how I keep up with  the news that I need to know, so I follow Jo Confino, Heidi MooreJoel Makower,  Andy RevkinBryan WalshTom PhilpottDavid Biello, Marcus Chung and Aman Singh. It’s also how way I keep up with the news that I want to know, so I follow Adam Kilgore, Buster Olney, Keith Law, Sam Miller@GioGonzalez47 and @ThisisDSpan. I follow colleagues at Fortune like Adam Lashinsky, economists who write for the public (thanks, @EconTalker!)Twitter has become what the newspaper industry once wanted to create on the Internet, a product informally dubbed “the daily me” that gave each reader news tailored to his or her interests.

imgres

So when I heard that Biz Stone, the co-founder of Twitter, and author of a new book about values and business was coming to Washington, I decided to hear what he had to say. I wasn’t disappointed. I wrote about Biz’s talk and his new book, Things a Little Bird Told Metoday in the Guardian Sustainable Business.

Even if you have little interest in Twitter, the book is worth reading. Here is how my Guardian story begins:

How should we define success in business? Biz Stone, the co-founder of Twitter, says that to be judged successful, a company needs to make money, make the world a better place and bring joy to the people who work there.

“It’s a ridiculously high bar,” he says. “But if you don’t set the bar high, you’re never going to get there.”

Stone has written a new book called Things a Little Bird Told Me: Confessions of the Creative Mind. The book is less about the mind than the heart, less about creativity than values and less about Twitter (and that little bird) than about Stone, an unabashed idealist and, it would appear, a genuinely nice guy. This is the rare Silicon Valley story with little to say about technology, venture capitalists, monetizing users and IPOs but a lot to say about how listening, empathy and generosity can help build a sustainable business and change the world.

“It may sound like a lofty goal,” Stone writes,”but I want to redefine capitalism.”

Untangling the lexicon of sustainability

Douglas Gayeton

Douglas Gayeton

Words can illuminate. Words can mislead. Words matter.

That’s one reason why I’m intrigued by Douglas Gayeton’s videos, books and “information artworks,” all of which are part of a vast and sprawling series called The Lexicon of Sustainability. They’re designed to help people separate what’s b.s. from what’s real in the world of sustainability.

Gayeton’s focus, so far, has been on food, and that’s smart. Nowhere is there more confusion about what’s sustainable, and what’s not, than in the supermarket — where claims like “all natural” and “multigrain” and “no sugar added” hide as much as they reveal.

I wrote a story about Gayeton the other day for Guardian Sustainable Business. Here’s how it begins:

Art has long inspired environmental activism. The photographer Ansel Adams, whose iconic black-and-white images of the American west helped to build support for the US National Park Service, served on the board of the Sierra Club for 37 years, working closely with David Brower, the club’s first executive director.

So it’s fitting that The Lexicon of Sustainability, a collection of artworks and short films by Douglas Gayeton that are designed to educate and activate people, have come to the David Brower Center, the nerve center of green business and environmental activism in Brower’s hometown of Berkeley.

Gayeton’s Lexicon of Sustainability artworks and films are based on a simple premise, he said. He explained that people can’t be expected to live “greener” lives, or act on behalf of the planet, until they better understand the language of sustainability. “Remember,” the films say, “your words can change the world.” This first series of works exploresfood and farming; future series will explain water and climate.

“The term sustainability has been totally debased,” Gayeton told me. “You can find sustainable shoes. You can find sustainable soda. Anything can be sustainable. People have hijacked the term. My wife and I thought, ‘Why not take it back?

The best way to understand what Gayeton is up to is to check out his artworks or watch one of his films. here’s one about eggs that told me things I didn’t know. The film is courtesy of PBS.org and you can read the rest of my story here.

Yet another reason to eat less meat

chickens-4The more I learn about the way most chickens, pigs and cows are raised and slaughtered in America, the less appetite I have for meat. I’m not a vegetarian, and may never become one. But, hey, I’ve given up the NFL. I’d like to give up industrial meat, too.

I’ve long been aware of the negative environmental impacts of factory-produced meat. There’s plenty of evidence that the meat-heavy American diet isn’t good for our health. We’re learning than the overuse of antibiotics in animal agriculture puts human health at risk. And chickens and pigs raised for food are confined in cages and crates barely larger than their bodies. It’s not a pretty picture.

Last week. at a forum organized by the New America Foundation called The New Meat Monopoly: The Animal, The Farmer, and You in the New Age of Global Giants, I heard about another reason to avoid factory-farmed meat: Big meat companies, and in particular Tyson Foods, have grown so powerful that they have made life harder than it needs to be for small-scale farmers and ranchers. At the Washington event, farmers, ranchers, anti-trust experts and animal welfare advocates lined up to pillory the big guys.

Among the speakers at the event was  New America Foundation fellow Christopher Leonard, the author of a well-reviewed new book called The Meat Racket:  The Secret Takeover of America’s Food Business. Leonard argues in the book (which I haven’t read, but hope to) that companies like Tyson “keep farmers in a state of indebted servitude, living like modern-day sharecroppers on the ragged edge of bankruptcy.” They are able to do so in part because many farmers have only one or two customers to sell to, so the customers hold all the cards.

Subsequently, I read Obama’s Game of Chicken, an excellent 2012 article Lina Khan in the Washington Monthly about abuses of power by companies like Tyson and Pilgrim’s Pride, and how Obama’s USDA and DOJ have failed to curb them. Khan, who’s also affiliated with the New America Foundation, describes in rich detail what she calls “the stark and growing imbalance of power between the farmers who grow our food and the companies who process it for us, and how this imbalance enables practices unimaginable in any competitive market.”

I wrote about the New America event last week for Guardian Sustainable Business. Here’s how my story begins:

Like politics, industrial-scale meat production creates strange bedfellows. Animal welfare advocates are joining up with farmers, environmentalists and supporters of stronger antitrust laws in the hope of engaging consumers on the issues involving the meat they buy. The aim? To counter the power of big meat companies like Tyson Foods and JBS, the world’s largest protein company and the owner of brands including Pilgrim’s Pride and Kraft.

“Maybe it’s time for a citizens revolt,” said Barry Lynn, director of the markets, enterprise and resiliency initiative at the New America Foundation. Lynn was speaking at a half-day forum in Washington called “The New Meat Monopoly: the animal, the farmer and you in the new age of global giants“.

The accusations thrown at the global meat giants were mostly familiar. By raising and slaughtering chicken, pigs and cattle on a large scale – about eight billion chickens will be raised and killed this year in the US – these companies squeeze out family farmers, treat animals cruelly, create waste and air pollution, and feed their livestock antibiotics that, over time, put human health at risk and raise healthcare costs, at least according to their critics.

What’s more, these critics argue, is that the meat industry’s consolidation and power have been supported by government policy. Subsidized corn and soy reduce the price of meat. Bank loans to farmers are backstopped by the USDA’s Farm Service Agency. Government regulations make it harder to build and operate small-scale slaughterhouses.

Costco, Trader Joe’s, QuikTrip and the “good jobs strategy”

zton_book-257x300As the issue of income inequality takes center stage in Washington, creating risks to the reputations of some of America’s biggest employers, such as Walmart and McDonald’s, Zeynep Ton’s new book, The Good Jobs Strategy, could not be more timely.

Ton, who teaches at MIT’s business school, argues that smart companies invest in their employees, who provide superior service to customers, who become loyal, thus generating profits and shareholder returns. What’s more, she says, this strategy works in the brutally competitive, low margin retail industry, at such companies as Costco, Trader Joe’s, QuikTrip and the big Spanish retailer Mercadona.

I met Zeynep Ton last week at the Hitachi Foundation in Washington, and wrote about her book, and her ideas, today in Guardian Sustainable Business.

Here’s how my story begins:

About 46 million Americans, or 15% of the population, live below the poverty line, and about 10.4 million of them are the working poor. They bag groceries at Walmart or Target, take your order at McDonald’s or Burger King, care for the sick, the elderly or the young.

Conventional wisdom says that’s unavoidable: to stay competitive, keep prices low and maximize profits, companies, particularly in the retail and service industries, need to squeeze their workers. But in a provocative new book, The Good Jobs Strategy, author and teacher Zeynep Ton argues that the conventional wisdom is wrong. Instead, she says, smart companies invest in their employees, and they do so to lower costs and increase profits.

Of course, the idea that companies need to properly reward their key employees is hardly radical. That’s how business works on Wall Street and in Silicon Valley, where the competition for talent is fierce. But Ton, who teaches at the MIT Sloan School of Management, says that a good jobs strategy can also work in retail. In fact, she makes her case after a close study of four mass-market retailers who invest in their employees, keep costs low and deliver superior shareholder returns.

“It’s not the case that success comes from cutting labor costs,” Ton says. “Success can come from investing in people.” What’s more, she says, executives need to understand that that treating workers well “does not depend on charging customers more”.

You can read the rest here.

Regular readers will not be surprised to hear that I’m inclined to agree with Ton. Ten years ago, in my own book, Faith and Fortune, I reported on companies like Southwest Airlines, Starbucks and UPS that pursue their own version of a “good jobs strategy.” To her credit, Ton has shown that the strategy works in retail, and that it can actually help drive prices lower–a potentially valuable lesson for companies like Walmart and McDonald’s.

Zeynep Ton

That said, her book raises a question that is hard, at least for me, to answer: If the good jobs strategy is so good, why don’t more companies embrace it? For that matter, why haven’t those companies that treat their employees well trounced their competitors? In theory, the companies that practice a “good jobs strategy” should be able to attract the best people, deliver the best customer service and force their rivals to copy them or suffer. That’s the way markets are supposed to work.

I put this question to Ton and she offered two answers. First, markets are imperfect. Second, the “good jobs strategy” is hard to execute because it requires redesigning workplaces, providing lots of training, finding the right balance between standardizing tasks and empowering employees, and so forth. Maybe. But I suspect there are other reasons why the “good jobs strategy” has not swept across America. Your thoughts are most welcome.

The future

9780300176483The bet between the biologist Paul Ehrlich and the economist Julian Simon, which was described as  “the scholarly wager of the decade” by the Chronicle of Higher Education, was settled without drama–or graciousness. As Paul Sabin writes in The Bet: Paul Ehrlich, Julian Simon and Our Gamble over Earth’s Future:

One day in October 1990, Julian Simon picked up his mail at his house in suburban Chevy Chase, Maryland. In a small envelope sent from Palo Alto, California, Simon found a sheet of metal prices along with a check from Paul Ehrlich for $576.07. There was no note.

It was a victory not just for Simon but for optimists everywhere, and so a fitting way to start the year of 2014. The two men–who did not like one another–had in 1980, at Simon’s urging, placed a $1,000 bet on the price of five metals ten years hence. Ehrlich, whose book The Population Bomb warning of a coming global catastrophe had made him a celebrity, as well as one of the most influential environmentalists of all time, believed that food, energy and commodities would all grow scarce, and thus more expensive over the decade. Simon, a free-market economist, had enormous faith in the power of markets, prices and innovation to solve problems. (Before the bet, Simon was best known as the inventor of the auction system used by airlines to pay passengers not to take overbooked flights.) Between 1980 and 1990, the prices of the five minerals–chromium, copper, nickel, tin and tungsten–had fallen by an average of almost 50 percent.

Simon was lucky as well as smart. A global recession in the early 1980s depressed the prices of metals, and they never recovered. As Sabin reports in his first-rate and very readable book, economists who ran simulations of the bet during every 10-year period between 1900 and 2008 found that Ehrlich would have won the bet 63 percent of the time. Yet the history of the past 45 years, since Ehrlich published The Population Bomb, weighs heavily in favor of Simon’s worldview. Market signals, human ingenuity and technological progress have solved problems that Ehrlich said would doom us all. [click to continue...]

The NFL and brain injury: That’s entertainment?

Are you ready for some brain injuries?

Are you ready for some brain damage?

Fifteen years ago, with my friend and co-author Bill Carter, I wrote a book about the TV show Monday Night Football, which helped build the phenomenal popularity of the NFL. I was a big football fan then. So much so that I didn’t notice until last week that the opening sequence of Monday Night Football — ARE YOU READY FOR SOME FOOTBALL!!! — featured the helmets of the opposing teams crashing together.

A prescription, in other words, for brain injury.

The image flashed by briefly in the gripping and occasionally horrifying PBS Frontline documentary League of Denial, based on the book of the same name by investigative reporters Mark Fainaru-Ward and Steve Fainaru. Watch the program if it comes around again, or watch it on the web.

As regular readers of this blog know, I gave up watching the NFL about a year ago. But I decided to revisit the topic in my latest story for Guardian Sustainable Business.

Here’s how it begins:

Garment workers in Bangladesh and coal miners in India risk injury or death on the job. Their plight evokes outrage from advocacy groups and corporate-responsibility gurus.

Players in the National Football League are at risk, too – at risk of losing their mind, quite literally. Yet professional football remains America’s favorite sport, generating close to $10bn a year, with not much more than an occasional murmur of concern.

Strange.

Of course, any football fan knows that the game is violent and dangerous, especially at the pro level. Powerful men collide at high speed, and a bone-jarring tackle can break a leg or, occasionally, a neck.

But football is dangerous in another, more insidious way, as we were reminded last week by the publication of League of Denial: The NFL, Concussions and the Battle for Truth, an examination of football’s concussion crisis by investigative reporters Mark Fainaru-Ward and Steve Fainaru. As the book and an accompanying PBS Frontline documentary vividly demonstrate, football also is inherently dangerous to the brain – an inconvenient truth that the NFL went to extraordinary lengths to hide, deny and muddle.

Of course, as I note in the story, NFL players are paid a lot better than garment workers or coal miners. And today’s players surely are aware of the risks they face.  But the price they pay – brain damage that robs them of their very sense of self – is terribly steep. And to what end? To make our Sunday afternoons and Monday nights a little more fun? So corporate sponsors can sell beer and cars?

Frontline is produced by a PBS station in Boston, which sent a reporter out to get reaction from Bill Belichick, the coach of the New England Patriots, and star quarterback Tom Brady.

Belichick said:

First of all, I’m not really familiar with whatever it is you’re referring to, whatever this thing is. But it doesn’t make any difference whether there is or isn’t one going on. We have our protocol with all medical situations, including that one and that’s followed by our medical department, which I’m not a doctor and I don’t think we want me treating patients.

What we do in the medical department, that’s medical procedures that honestly I don’t know enough to talk about. But I can say this, there’s nothing more important to a coach than the health of his team. Without a healthy team, you don’t have a team. We try to do everything we can to have our players healthy, to prepare them, to prevent injuries and then to treat injuries and to have them play as close to 100 percent as we can because without them, you have no team.

Hmm. The Pats do “everything we can to have our players healthy…because without them, you have no team.” And if they lose their minds after they retire, well, you win some and you lose some.This guy has a heart of gold.

In fairness, the NFL is doing a better job these days of treating and preventing concussions. There have been rules changes, medical personnel on the sidelines, better understanding among all of the real risks of contact. Finally. But, remember, football is played in college and high schools, too, where kids model themselves on the hard-hitting pros. Frontline put a spotlight on a college and a high school player who, shockingly, suffered from brain injuries that appeared to be–no, we can’t be sure–related to football.

Do they understand the risks they are taking? Who’s looking out for them? Clearly not the NFL.
