Roger Hallam stands as one of the most outspoken and controversial figures in the fight against climate change. As a co-founder of Extinction Rebellion and Just Stop Oil, he captures attention with bold actions and unapologetic words. His journey from an organic farmer to a jailed activist reveals a man driven by urgency and a belief that radical change offers the only hope for humanity’s survival. With the world facing rising temperatures and ecological collapse, Hallam’s story demands a closer look—especially now, in March 2025, as his latest legal battles unfold.
This article dives deep into Hallam’s life, his movements, and his unrelenting push for climate action. We explore his recent sentence reduction, his strategies for shaking up systems, and the mixed reactions he sparks. By the end, you’ll understand why Hallam remains a lightning rod in the climate crisis conversation.
From Farmer to Firebrand: Hallam’s Early Life
Roger Hallam’s story begins far from the chaos of protests and courtrooms. Born in 1966 in the United Kingdom, he grows up with a quiet, grounded life that eventually leads him to farming. He settled in Wales, where he runs a small organic farm near Llandeilo. For years, he nurtures the land, growing crops and living simply. However, nature soon delivers a harsh lesson. Extreme weather—weeks of relentless rain—destroys his harvests and pushes his business into bankruptcy. This moment marks a turning point. Hallam sees firsthand how climate change ravages lives, and it ignites a fire within him.
Determined to understand how to fight back, Hallam shifts gears. He enrolls at King’s College London to pursue a PhD in civil disobedience and radical movements. His research focuses on how ordinary people force big changes when systems fail them. During this time, he tests his theories with action. In 2017, he spray-painted “Divest from oil and gas” on the university’s walls to demand it ditch fossil fuel investments. Security drags him off campus, but his hunger strike soon follows. After 14 days with little more than orange juice, King’s agrees to pull £14 million from fossil fuels. Hallam learns a key lesson: disruption works.
Building Extinction Rebellion: A Movement Takes Root
Hallam’s academic days set the stage for something bigger. In 2018, he teamed up with Gail Bradbrook and Simon Bramwell to launch the Extinction Rebellion, or XR. The group bursts onto the scene with a clear mission: use non-violent civil disobedience to force governments to act on climate change. Hallam believes the world teeters on the edge of ecological collapse, and polite petitions won’t cut it. XR’s early actions—like shutting down London streets in April 2019—grab headlines and rattle authorities. Over 1,000 arrests pile up, but the message spreads fast.
Hallam’s strategy draws from history. He studies Gandhi and Martin Luther King Jr., blending their tactics with his own flair. He argues that mass arrests amplify a cause, turning quiet grumbles into loud demands. XR grows quickly, sprouting chapters worldwide. Yet, Hallam’s blunt style stirs trouble. In 2019, he told German newspaper Die Zeit that the Holocaust ranks as “just another fuckery in human history.” Outrage erupts. XR’s German branch and the UK group distance themselves, and Hallam apologizes for his “crass words.” Still, the incident shows his knack for sparking debate—and division.
Just Stop Oil: Escalating the Fight
After stepping back from XR, Hallam doesn’t slow down. He co-founds Just Stop Oil in 2022, a group laser-focused on ending new fossil fuel projects. The stakes feel higher now, with climate reports warning of catastrophe if emissions don’t drop fast. Just Stop Oil takes XR’s playbook and cranks it up. Activists glue themselves to roads, throw soup at famous paintings, and block oil refineries. Hallam cheers these moves, calling them necessary to “act like the truth is real.” Critics slam the stunts as reckless, but supporters say they force people to notice.
Hallam’s rhetoric sharpens too. He warns of “mass rape, mass slaughter, and mass starvation” if society doesn’t pivot. His words aim to jolt the comfortable out of apathy. In 2021, he leads sit-down protests on UK highways, snarling traffic for hours. Then, in 2022, he joins a Zoom call that lands him in hot water. He urges activists to block London’s M25 motorway—a plan that later unfolds, causing massive delays. Police arrest him, and a judge slaps him with a five-year prison sentence for conspiracy to cause a public nuisance. Hallam’s supporters cry foul, but his opponents cheer the crackdown.
The Controversy: Hero or Villain?
Hallam splits opinions like a cracked windshield. Supporters crown him a prophet, risking everything to save the planet. They point to his farm’s ruin and his arrests as proof of his sincerity. In a 2025 Guardian piece, scientist Bill McGuire joins Hallam to warn of “truly horrifying” times ahead. Fans say his bluntness cuts through the noise—someone has to yell when the house burns down. Plus, his wins, like King’s divestment, show results.
Detractors paint a darker picture. They brand him an “arrogant liability,” blind to his privilege as a white, middle-class man. His Holocaust remarks still haunt him, with some XR members never forgiving the stain. Others slam his tactics as elitist—working-class people can’t afford arrests or lost jobs, they argue. In 2019, a follower blasts him on Facebook: “Prison isn’t a pantomime for everyone, Roger.” His dire predictions—like billions dying if warming hits two degrees Celsius—also draw flak. The New York Times once nitpicks his numbers, though Hallam fires back, asking what “uninhabitable” really means.
