The HBO series “The Last of Us” is set to return for its second season on April 13th, continuing its exploration of a fictional fungal pandemic that turns humans into zombie-like creatures. While this premise may seem exaggerated, scientists are genuinely studying the evolution of fungi, climate change, and the potential risks they pose to various species.
The show features Cordyceps fungi, which in the series evolve to infect humans due to climate change. However, real-life experts, like Dr. Jim Kronstad from the University of British Columbia, explain that these fungi primarily infect insects and are unlikely to adapt to humans due to our body temperature and immune system. Season 2 introduces the concept that zombies can also spread fungal spores through the air, enhancing realism regarding how humans might contract fungal infections.
The series highlights climate change’s role in potentially expanding the range and virulence of harmful fungi. For example, the rise in temperatures is linked to the increasing prevalence of coccidioidomycosis, or valley fever, which thrives in hot, dry areas. As climate conditions change, these fungi may spread into new regions and pose increased risks to human health and agriculture.
Despite the terrifying portrayal of fungi in the series, it’s important to note that fungi are vital to ecosystems, contributing to nutrient recycling and playing significant roles in medicine and food production. Scientists continue to monitor how climate change may affect fungal behavior, recognizing that while the notion of a zombie apocalypse is fictional, the real-world implications of fungal adaptation to climate change are serious and warrant attention.
