Healthy Soil, Coming to a Theater Near You: 5 Lessons From 'The Biggest Little Farm'
By Karen Perry Stillerman
An email in my inbox last month caught my attention. It was from author, environmental advocate, and Academy Award-winning film producer Laurie David (An Inconvenient Truth), and it offered a preview of The Biggest Little Farm, a new documentary film David had coming out soon. "I promise you that any person that goes to see this film will leave inspired and caring a whole lot more for the planet," her note said. "I promise you it will help your organization achieve your goals!"
I clicked on the link, watched the trailer, was intrigued. The movie looked gorgeous. But would it hold up to scrutiny from skeptical agricultural scientists?
A few days later, in a conference room with several members of the Union of Concerned Scientists (UCS) food and agriculture team, I dimmed the lights and let the film roll. The Biggest Little Farm (in theaters this month) chronicles the adventures of filmmaker John Chester and his wife Molly as they leave their lives in Los Angeles behind to start a diversified farm on an exhausted piece of land north of the city, where they intend to live and grow food "in perfect harmony with nature."
At first, the storytelling seems to veer toward the precious. John documents the promise they made to their rescue pup Todd about how much he'd love being a farm dog. The narration, over cute animation, extols the idyllic life John and Molly imagine for themselves. But I soon realized he was setting up viewers for the same jolt he and Molly would soon get — repeatedly — about the harsh realities of farming, especially when you're trying something new and complex.
Because it turns out this kind of farming isn't all rainbows and puppies and adorable baby goats. It's also exhausting and sometimes heartbreaking. Before long, the story got real — very real — and I was hooked. After the credits rolled, my colleagues' reviews came in:
A really beautiful, honest, and engaging film. It shows the many tough challenges of farming with nature rather than against it, but leads with the opportunities and a hopeful optimism.
I don't think I've ever seen such a stunning illustration of the ecology of diversified farming – the challenges, the potential, and all the interconnectedness of a complex farm ecosystem.
More dead chickens! Why did you make me watch this??
Indeed, midway through the film, the casualties start to pile up. John, Molly and their team face a seemingly never-ending string of predator attacks, pest and disease outbreaks, and other deadly natural phenomena as they struggle to make Apricot Lane Farms a sustainable enterprise. Although the relentless mishaps challenge their core belief in working with nature rather than against it, they persist, learning something from each experience and finding creative ways to adapt.
Their story, while unique in many ways, contains some key lessons for U.S. agriculture:
Soil is paramount.
When the Chesters first arrived at Apricot Lane Farms, their newly acquired soil was so compacted and devoid of organic matter, they could hardly break it with a shovel. "The soil is dead," John says flatly. "And we have no idea how to bring it back to life." But with the help of consultant and soil guru Alan York, they set about enriching it. "Plants build soil," Alan said as they seeded cover crops. They also installed a state-of-the-art compost tea system and added animals (so many animals!) for their manure. And indeed, by the end of the film—which spans a seven-year period of historic California drought followed by an unusually wet year—the Chesters' spongier soil seemed to have paid off, as it held water better during dry periods and soaked up more of it when the rains fell. At a time when climate change is driving more weather extremes in every part of the country, building healthy soil will be critical to ensuring that farmers can be successful.
2. Increasing a farm’s biodiversity is critical (and hard).
Someone recently said to me that farmers are the only manufacturers who work outside, completely exposed to the elements. There's truth in that, for sure, but the choice of the word "manufacturers" is revealing. Factories typically make one thing, over and over, day in and day out. And farming in the United States has become a lot like that—an overwhelmingly industrial process, divorced from nature and, in fact, often fighting it tooth and nail. In the film, we see Alan explaining how the Chesters must emulate how natural ecosystems work (we call this agroecology). His mantra: "Diversify, diversify, diversify." John and Molly take this to the extreme, eventually farming 200+ crops and animals across pastures, orchards, and a large vegetable garden. A plethora of wildlife also returns, including new pests that require more creativity and further diversification to combat. Alan promises all this diversity will become simplicity, but as John notes, "a simple way of farming is just not easy."
3. Few farmers can go to the lengths the Chesters have. But most don’t need to.
The 76 varieties of stone fruit trees John and Molly now tend is…probably a bit much for most farmers. And without access to investors like they recruited, few farm startups can afford fancy composting systems, miles of new irrigation line, and the costs associated with repeated trial and error. It is never clear, in the film, how much up-front and continued investment was necessary to do what they did at Apricot Lane Farms (though we can assume it was a lot). Nor do we know at what point in the saga that investment was fully recouped, if it has been. But recent research has shown that even more limited and lower-cost efforts at diversification on farms—for example, expanding from two crops to three or four, or planting prairie strips around the edges of crop fields—can have substantial benefits. And federal farm programs provide help (though not nearly enough) for farmers to do such things.
4. One way or another, the ecological debts of our industrial farming system must be paid.
Apricot Lane Farms required substantial upfront investment not only because the Chesters had ambitious plans, but also because they needed to pay down an enormous ecological debt racked up on that piece of land over the years. Industrial agriculture has been called an "extraction industry" because it takes nutrients from the land without replacing them, allows precious soil to wash or blow away, and sends rainwater running off the surface rather than percolating down to refill underground aquifers for later use. Due to decades of short-sighted management, this is the situation on farmland all across this country. And while John, Molly, and their investors had the means to take on Apricot Lane's ecological debt, it's not fair or realistic to expect farmers to make up for the damage caused by industrial practices and the public policies that have incentivized them. Rather, "The Biggest Little Farm" shows once again why shifting agricultural policies to help farmers diversify the landscape and rebuild their soil and is a smart investment in the future.
5. Nature is breathtakingly beautiful.
The film's message is in line with what the science tells us about farmland diversification and healthy soil, and it comes at a time when legislators in many states and in Congress are looking to expand policy supports and public investments to help more farmers advance soil health. Even though Apricot Lane is just one farm, and a unique one at that, my hope is that this film adds to the conversation. But you don't have to be an advocate for healthy soil policy to appreciate the movie, which above all is visually stunning and brimming with optimism. You'll marvel at the ways John Chester's cinematography captures the beauty and devastation of nature and life on a diversified, ecologically-based farm—from aerial footage of painstakingly designed orchards to images of playful lambs and terrifying wildfires, infrared footage of nocturnal predators, and superslomo shots of the hummingbirds and beneficial insects who return as part of the farm's renewal. If you like that iPhone commercial, you'll find this film equally appealing.
The Biggest Little Farm opens this Friday, May 10, in Los Angeles and New York, and nationwide May 17.

It is undisputed that vitamin D plays a role everywhere in the body and performs important functions. A severe vitamin D deficiency, which can occur at a level of 12 nanograms per milliliter of blood or less, leads to severe and painful bone deformations known as rickets in infants and young children and osteomalacia in adults. Unfortunately, this is where the scientific consensus ends.
Where Does the Deficiency Begin?<p>Nobody knows exactly how much vitamin D a person actually needs. The question of when a deficiency starts is correspondingly controversial. However, vitamin D is becoming increasingly popular.Not only is the pseudo-scientific literature on the "sun vitamin" experiencing an upswing, but the number of published studies has also increased enormously in recent years. For example, in 2019 <a href="https://academic.oup.com/edrv/article/40/4/1109/5126915" target="_blank">a study found that</a> Vitamin D is responsible for keeping the skeleton functional and is associated with cardiovascular diseases, type 2 diabetes and various types of cancer. <br></p>
An All-Rounder<p>Vitamin D levels in the body rise and fall according to sun exposure. If sufficient UV rays reach the skin, the body is able to produce the vitamin itself. However, the human body only derives an estimated 10 to 20 percent of its daily requirement from food.</p><p>The vitamin D that we synthesize from sunlight or food is not biologically active at first. Before the kidneys can produce the biologically active form of the vitamin, known as calcitriol, and release it into the blood, some metabolic processes must take place beforehand.</p><p>In addition, many organs have receptors to which the precursor of calcitriol binds. Further, this substance is also present in blood.</p><p>From this precursor, the organs then produce calcitriol themselves, which the body then uses for countless other processes in the body. This form of vitamin D thus regulates insulin secretion, inhibits tumor growth, and promotes the formation of red blood cells as well as the survival and activity of macrophages, which are important for the <a href="https://www.mdpi.com/2072-6643/5/7/2502/htm" target="_blank">immune system.</a></p>
Low Vitamin D, Severe COVID-19 Disease?<p>A research study carried out <a href="https://www.sciencedirect.com/science/article/pii/S2352364620300067?via%3Dihub" target="_blank">at the University of Hohenheim</a> has now established a link between vitamin D deficiency, certain previous diseases, and severe cases of COVID-19.</p><p>According to the study, "there is a lot of evidence that several non-communicable diseases (high blood pressure, diabetes, cardiovascular diseases, metabolic syndrome) are associated with low vitamin D plasma levels. These comorbidities, together with the often accompanying vitamin D deficiency, increase the risk of severe COVID-19 events."</p><p>"This statement is completely correct," said Martin Fassnacht, head of endocrinology at the University Hospital of Würzburg. However, he qualifies that it is a pure association, "i.e. a mere observation that these events occur together.</p><p>Dr. Fassnacht is very critical of the hype surrounding vitamin D, but not because he denies the vitamin serves important functions. However, studies on humans have not been able to show that vitamin D has the healing powers many often propagate.</p><p>Fassnacht says, "If you take a closer look, the hopes that the administration of vitamin D has a healing effect have not been confirmed so far."</p>
Association Versus Intervention Studies<p>Many studies on the vitamin are association or observational studies. "By definition, these studies cannot prove the causal relationship, but only point to mere correlations," said Fassnacht. The physician tries to illustrate this with an example:</p><p>"Imagine two groups of 80-year-olds. One group is spry, active and does sports. If you compare them with another group living in nursing homes, the difference in vitamin D levels will be dramatic. Life expectancy would also be extremely different."</p><p>But to try to explain the difference in fitness by vitamin D status alone is far too simplistic. "Vitamin D levels are a good measure of how sick someone is. But not more," says Fassnacht. </p><p>According to Fassnacht, none of the intervention studies carried out to date -- that specifically examined the effect of vitamin D on various diseases -- has been able to confirm the previous association and laboratory studies or the presumed positive effect of vitamin D.</p>
Further Research Is Needed<p>"If a coronavirus infection is suspected, it is therefore absolutely necessary to check the vitamin D status and quickly correct any possible deficit," said the recommendation of the paper published by the University of Hohenheim.</p><p>"Studies are underway to see whether vitamin D helps in COVID-19 infection, but I personally do not believe that this is really the case," says endocrinologist Fassnacht. Nevertheless, he says it is of course useful to carry out these studies.<br></p><p>"I don't want to rule out that there are actually subgroups of people who benefit from an additional vitamin D dose," he says. After all, this has been proven to be the case with a severe deficit.</p><p>In view of the study situation, Fassnacht does not think much of preventive, nationwide vitamin D substitutes. "My belief that the vitamin helps somewhere is very low. But, of course, I can be wrong."</p>
