🌱 Beneath our feet lies a hidden network so vast it could reshape how we understand Earth’s climate.
Researchers have mapped the pathways formed by mycorrhizal fungi across the planet’s topsoil—and estimate that these underground networks store roughly 300 megatons of carbon.
In just one teaspoon of soil, there may be up to 10 meters of fungal threads quietly connecting plants, moving nutrients, and transporting carbon below ground.
These microscopic supply routes are astonishingly fast. Scaled to human size, their transport speed would equal nearly 248 miles per hour.
Every year, mycorrhizal fungi may move around four billion tons of carbon dioxide into the soil—an amount equal to roughly 11% of annual human-generated emissions.
This hidden infrastructure has been beneath us all along: invisible, ancient, and essential to life on Earth. 🍄🌍
