The subgenre of eco-horror exists to remind us that the Earth and natural world were here long before each and every one of us, and will remain so long after we depart this mortal coil. It is horror rooted in the idea that nature does not exist to serve or be controlled by short-sighted humans, and can indeed fight back. Whether it’s killer animals, toxic contamination, mutation, or the general sense that the planet is fed up with our abuse, eco-horror is one of the most enduring and prescient corners of the genre.
That said, it makes perfect sense that eco-horror began to gain real momentum in the 1970s. While examples of eco-horror existed long before that, Earth Day launched in 1970 as part of the modern environmental movement. The EPA was created that same year amid growing public anxiety over pollution, pesticides, and the compounding damage being done to our air, water, and land. That combo made the decade a fertile breeding ground for stories about nature striking back. You can almost feel the era’s fear of industrial excess seeping straight onto the screen.
Even today, eco-horror still works because the anxieties behind it, unfortunately, never went away. Despite all the advances made in the last few decades, science remains constantly questioned, planned obsolescence keeps landfills full, and extreme weather events are only increasing.
If you, too, are feeling frustrated and have sympathy for the planet that sustains life for us all, here are 7 eco-horror films to check out, along with where to stream them, to help channel that angst.
The Last Winter (2006)
Larry Fessenden’s The Last Winter blends snow horror with eco-horror, taking place in the freezing, godforsaken Arctic. Starring Ron Perlman, Connie Britton, James LeGros, Zach Gilford, and Kevin Corrigan, the movie kicks off as an oil company’s push into the Alaska tundra taps into something unexpected and very dangerous. The crew soon begins to experience eerie visions, disappearances, and paranoia as the land itself seems to rebel against their presence.

Frogs (1972)
A cheesy, but classic example of the subgenre, Frogs is directed by George McCowan and stars a young Sam Elliott as wildlife photographer Pickett Smith. While documenting some curious ecological conditions in the water surrounding an island estate, Pickett nearly gets killed when his canoe is capsized thanks to the wealthy Crockett kids and their fancy speedboat. Feeling bad, the Crocketts invite Pickett back to their mansion to clean up, meet the fam, and celebrate the July 4th holiday. However, members of the party soon begin to perish under mysterious circumstances, and Pickett finds himself smack dab in the middle of an unlikely and ugly battle between man and nature.

Unearth (2020)
Starring Marc Blucas and genre icon Adrienne Barbeau, Unearth is a slow-burn fracking nightmare set in rural Pennsylvania, where two neighboring farm families are locked in a tense standoff when one of them agrees to lease their land to a natural gas company. Once drilling begins, the ground coughs up something deeply unwelcome, immediately putting both families in danger. Along with the film’s obvious environmental aspects, Unearth provides an interesting look at the interconnected economic issues that often play a role in such short-sighted decision-making and the ripples of impact they create.

The Toxic Avenger (1984)
The gloriously deranged Troma classic starts with bullied janitor Melvin Ferd getting humiliated, falling into a vat of toxic waste, and then emerging as a mutated, mop-wielding avenger with superhuman strength and a very specific sense of justice. Set in Tromaville, New Jersey, Melvin turns his new special set of skills against the local scumbags, crooked officials, and assorted human garbage terrorizing the town, becoming an unexpected underdog hero in the process. In classic Troma fashion, it’s a movie that is as much splatter spoof and trashy revenge as it is a toxic-waste fever dream. Not all eco-horror has to be a total bummer, after all.

The China Syndrome (1979)
Though not a horror movie in the strictest sense, The China Syndrome fits neatly into the genre, tapping into the anxiety surrounding nuclear energy. In the movie, Jane Fonda plays a TV reporter who, along with her cameraman (Michael Douglas), uncovers a serious safety issue cover-up at a nuclear plant. Before they know it, the situation quickly escalates, putting millions of lives at risk. Released just twelve days before the real-world incident at Three Mile Island, the movie landed in 1979 with eerie force, and the questions it poses about the riskiness of industrial progress still pack a powerful punch.

Gaia (2021)
A gorgeously gruesome South African movie, Gaia tells the tale of an injured forest ranger named Gabi who encounters two off-grid survivalists whose devotion to the forest quickly becomes unnerving. Before long, Gabi learns that the beautiful plant life surrounding her temporary accommodations holds secrets and power much darker than she could ever imagine. Directed by Jaco Bouwer, the film leans hard into body horror, using its intense imagery to turn the natural world into something beautiful, sacred, and terrifying all at once.

The Bay (2012)
Directed by Barry Levinson, The Bay is a found footage eco-horror outing. Set in a Maryland coastal town, residents soon discover their water has been polluted by a local chicken farm. This then unleashes a parasitic outbreak that turns the Fourth of July into a full-blown body-horror catastrophe. With inspiration drawn from real environmental concerns around the Chesapeake Bay, the film leans hard into the idea that human carelessness and apathy is often much more terrifying than anything supernatural.
