How hundreds of small ‘Gardens of Eden’ guard against total deforestation in Ethiopia

‘The church is within the forest, the forest is inside the church.’

Ethiopia’s northern highlands were once covered by trees. But over the past century, development and exponential population growth have all but wiped out the region’s forests, transforming the landscape into an expanse of brown fields, given over to cattle grazing and agriculture. However, an aerial view of the region reveals small pockets of green with round buildings in the middle, dotting the barren expanses. Born of the centuries-old belief of the Ethiopian Orthodox Tewahedo Church that churches should be surrounded by forests so as to resemble the Garden of Eden, these sites have become valuable sanctuaries of biodiversity amid the extreme pressures of population growth. The Church Forests of Ethiopia explores how the Ethiopian ecologist Alemayehu Wassie is partnering with church leaders in a last stand against deforestation – an inspiring and uncommon partnership between science and religion.

Meet the British bouncer in LA on an expired visa who has no time for immigrants

Steve is a former weightlifter who still keeps up with quite a few hobbies: fitness, heavy metal music, clay sculpture, bikes, motorcycles, and lots and lots of weapons. He works as a bouncer outside a Los Angeles nightclub, making small talk with the (often over-served) young patrons, and throwing out troublemakers. And, as he’ll tell anyone who’ll listen, he hates what immigration is doing to the country – despite being a Brit who’s overstayed his own US visa by 25 years. Steve Is Undocumented captures him at a moment of transition, preparing for a move back to England with his wife, who is pregnant with twins. With their stylish and often wry profile, the directors Michael Barth and Kauai Moliterno build a complex portrait in just 10 minutes, capturing the many intricacies and blaring hypocrisies of Steve’s life and worldview.

After losing his sight, a skateboarder takes an unexpected path to realising his dreams

Nick Mullins fell in love with skateboarding as a teenager and, rather quickly, became quite skilled. As one of the best young skateboarders in the Detroit area, he was putting together a video to catch the attention of sponsors, when, after taking a rough but mostly innocuous fall, he scraped the side of his body and contracted a staph infection. He would barely escape with his life, and after waking up from a medically induced coma, realised he had gone blind. Believing he had no prospects – in skating or in life – he fell into a deep depression. The short documentary You and the Thing That You Love retells how Mullins would eventually realise his dreams, albeit by taking a very much unanticipated path. Capturing Mullins’s story with kinetic style, the US filmmaker Nicholas Maher avoids cliché to create a standout portrait of perseverance and love of craft – and one that can be savoured even if you don’t know your ‘blunts’ from your ‘fakies’.

Algorithms are sensitive. People are specific. We should exploit their respective strengths

The capabilities of algorithms and human brainpower overlap, intersect and contrast in a multitude of ways, argues Hannah Fry, an associate professor in the mathematics of cities at University College London, in this lecture at the Royal Institution from 2018. And, says Fry, planning for an efficient, ethical future demands that we carefully consider the respective strengths of each without stereotyping either as inherently good or bad, while always keeping their real-world consequences in mind. Borrowing from her book Hello World: Being Human in the Age of Algorithms (2018), Fry’s presentation synthesises fascinating studies, entertaining anecdotes and her own personal experiences to build a compelling argument for how we ought to think about algorithms if we’d like them to amplify – and not erode – our humanity.

New York’s 300-year-old trash becomes treasure in the hands of an urban archaeologist

Scott Jordan’s two-bedroom apartment in Queens, New York is filled with thousands of local artefacts, many of which date back centuries. Populating his shelves and drawers are glass bottles, porcelain dolls, pottery and even a gun from the Revolutionary War – all of them once buried far beneath New Yorkers’ feet, and many of which he’s repurposed to create original art. This small museum of recovered treasures comes from years of playing in the dirt and digging out landfills, cisterns and privies by hand. In The Artefact Artist, the US director Russ Kendall explores the buried history of cities, and how Jordan finds meaning and community in the process of searching for, discovering, and transforming objects others have left for trash.
