Ecological documentaries to watch

Six Inches of Soil

The recently released Six Inches of Soil puts industrial farming under scrutiny, making it one of the most thought-provoking eco documentaries to see right now. It tells the story of three young British farmers who are challenging the norm. Instead of artificial pesticides and fertilisers, giant fields of monoculture crops, intensive use of machinery and fossil fuels (which lead to soil degradation, biodiversity loss and climate change) the trio focus on agroecology – an approach to farming which works in harmony with nature rather than against it. We meet Anna Jackson, a Lincolnshire 11th generation arable and sheep farmer; Adrienne Gordon, a Cambridgeshire small-scale vegetable farmer; and Ben Thomas, who rears pasture fed beef cattle in Cornwall. The documentary follows them as they try to navigate a broken food system and adopt regenerative practices within their farming practices whilst also creating viable businesses.

Food, Inc 2

The eye-opening, Oscar-nominated Food, Inc 2, a sequel to the 2008 film of the same name, takes another deep-dive into the American food industry. It shines a light on the giant, profiteering (often unregulated) corporations who are taking over at an enormous cost to farmers, animals, the workforce, the planet and our health. The eco documentary focuses on ultra-processed food, tackling everything from mistreatment of migrant workers in the food industry to climate change and obesity. We learn about lab-grown meat which, albeit better for the environment in some ways, might not be as healthy as we’d like to believe, and consider whether additives are rewiring consumers’ metabolisms. Just a few of the issues this film, directed by Robert Kenner and Melissa Robledo, seeks to address.

The Biggest Little Farm

In The Biggest Little Farm, filmmaker John Chester and his wife Molly leave behind their busy lives in Los Angeles to revitalise a 200-acre barren plot of land, 40 miles north of the city, and turn it into a self-sustaining farm. This environmental documentary follows their eight-year journey as they establish Apricot Lane Farms, a traditional food farm, seeking to “harvest in harmony with nature”. We follow the ups and the downs as the couple establish Biodynamic Certified avocado and lemon orchards, a vegetable garden, pastures and over 75 varieties of stone fruits, as well as as look after their pigs, goats, sheep, chickens, ducks, guinea hens, horses, highland cattle, and one brown Swiss dairy cow named Maggie. All the while trying to create a well-balanced ecosystem, and treating the environment and the animals with the respect they deserve.

Wings Over Water

The rivers, lakes and wetlands of North America aren’t just majestic in their beauty, they’re also a vital lifeline for wildlife, from the herds of bison roaming the Great Plains to the bees that pollinate crops. Wings Over Water, which has won multiple awards, gives a bird’s eye view of the millions of magnificent birds that migrate along these “flyways”. It follows the epic journeys of three bird families in particular – the Sandhill Crane, the Yellow Warbler and the Mallard Duck. Narrated by actor Michael Keaton, who is an avid outdoorsman and passionate about wetlands conservation, and beautifully filmed in 3D high definition by Andrew Young, this is one of the most stunning eco documentaries you’re likely to see. But it also has a serious message, underlining the environmental dangers to the continued existence of the Prairie Pothole region that is so crucial to the future of migratory birds in North America.

Fashion Reimagined

Amy Powney – creative director of luxury London-based sustainable womenswear label Mother of Pearl – has forever been passionate about the future of our planet. This Becky Hutner-directed documentary charts Amy’s remarkable story as she sets about creating a sustainable fashion collection from field and farm to finished garment. The film begins in 2017, with Amy winning the BFC/Vogue award for Best Young Designer and the cash prize that comes with it. She decides to use the money to make an organic, traceable No Frills line of clothing that is socially and environmentally responsible. As we follow her three-year journey to create and launch the collection, along with her sidekick and brand manager Chloe, we’re taken from the MOP studio in Mile End to Uruguay, Peru, Turkey, Austria and Paris, meeting sheep farmers, cotton pickers, factory owners and fashion buyers along the way. A beautifully put together insight into sustainability in fashion.

Plastic Earth

Single-use plastic is a disaster for the environment on multiple levels – plastic production from fossil-based sources contributes to climate change, pollution and, of course, threatens so many of the planet’s species (marine life alone are harmed through entanglement and injury to ingestion and toxic contamination). However, this 100-minute documentary – written and directed by Janice Overbeck and Jack Winch, and presented by Rob Riggle – doesn’t just shine a light on the plastic crisis that our precious world is facing. It’s an intelligent, thought-provoking insight into the solutions and technologies currently being developed to combat – and hopefully solve – the disaster. Through interviews with scientists, engineers, researchers and pioneers, we meet the heroes trying to solve the planet’s plastic problem and learn all about the measures being taken to get this gargantuan issue under control.

Polar Bear

This is the 16th nature documentary to be released under the Disneynature label. Narrated by Oscar nominee Catherine Keener and directed by Alastair Fothergill and Jeff Wilson, the family-friendly film tells the story of a mother polar bear and her two cubs as they try to navigate the increasingly challenging world that polar bears face today. It flashes between when she was a cub travelling with her mother to being a mother herself, accentuating the multiple changes brought on by the climate crisis. And so you see their struggle to find food (at one point they’re forced to eat seaweed to quell their hunger), the melting ice, the desolation… Beautifully filmed and produced, it’s a poignant environmental lesson.

Our Great National Parks

While in office, Obama protected more public lands and waters than any other president in American history, so his smooth tones make for an apt accompaniment to this visually arresting series.

The documentary which inspired a legion of vegans, Cowspiracy looks at the impact of animal agriculture and the way it influences environmental destruction through global warming, water wastage and deforestation. It’s a controversial watch, mainly because of the fact that in recent years, some of its assertions have been disproved, (such as its claim that 51% of all greenhouse gases are produced by the industry), but it’s well worth watching for the valid question it raises over whether we really need to be eating so much meat.

Expect a film as much about humanity as conservation.
