Scientists Map Earth's Hidden Fungal Superhighway for the First Time
A Hidden Network Beneath Our Feet
Scientists have created the first comprehensive map of an vast underground fungal network that helps sustain much of life on Earth. This hidden "superhighway" stretches across the planet in ways that were previously unknown, and researchers are now beginning to understand its true scale and importance.
By the Numbers
The findings reveal just how extensive these fungal networks truly are:
- 110 quadrillion kilometers of underground fungal threads
- 4 billion tons of carbon dioxide transferred into soils each year
- Critical role in supporting plant growth and health
Why This Matters
These fungal networks—often called the "wood wide web"—connect plants and trees in complex relationships that allow for nutrient sharing, communication, and ecosystem resilience. The carbon transport function alone makes these networks a significant factor in climate regulation, acting as a natural carbon sequestration system.
The mapping effort represents a major advance in understanding soil ecosystems and how terrestrial life functions at a planetary scale. This research highlights how much remains to be discovered about the biological systems that sustain life on Earth.
