The hit HBO series “The Last of Us” is set to return for its second season on April 13, captivating fans with its terrifying concept of a fungal pandemic that turns humans into zombies. But how much of this chilling storyline is rooted in reality?
Scientists have studied the connection between fungal evolution and climate change, revealing threats fungi can pose to different species. One real fungus, Ophiocordyceps unilateralis, infects carpenter ants, manipulating their behavior to lead to their death.
However, experts say it’s not possible for cordyceps fungi to adapt from insects to humans due to body temperature and immunity limitations. The show’s depiction of zombies using tentacles to infect humans is also less realistic.
Climate change may, however, influence the spread and adaptation of harmful fungi like Valley fever, caused by Coccidioides fungus. Rising temperatures and droughts have been linked to increased growth and spread of this pathogen, with California experiencing a sharp rise in cases last year.
Furthermore, climate change threatens agriculture as plant-pathogenic fungi may spread to new areas, affecting global food security. Fungi also play vital roles in ecosystems, decomposing organic material and acting as carbon sinks.
While the idea of a fungal apocalypse remains fictional, scientists are taking seriously how warming temperatures might make some fungi more resilient and adaptable. With this in mind, we can enjoy “The Last of Us” for what it is – science fiction – but also acknowledge the real-world concerns about climate-driven changes in fungal infections.
