Earth’s Hidden Fungal Highway

Scientists just uncovered Earth’s hidden fungal highway — a vast underground network of arbuscular mycorrhizal fungi that spans the globe, moving carbon, water, and nutrients like a planet-wide circulatory system. Found in 110 quadrillion kilometers of fungal threads — nearly a billion times the distance to the sun — these networks are especially dense in grasslands and play a critical role in climate regulation, sequestering four billion tons of CO2 equivalent annually. Researchers mapped this global system using 16,000 soil samples and AI, revealing that these vital fungi are being lost faster than forests as grasslands are converted to farmland — a major conservation blind spot we can’t afford to ignore.
