Why

The fungi gather water and nutrients for plants in exchange for carbon-rich sugars, extending plant root reach and collectively containing around 300 megatons of carbon.

The Frontline Impact

How this affects you

This discovery highlights a vastly overlooked carbon storage system containing approximately 300 megatons of carbon and underscores the critical role of these fungal networks in sustaining over 70% of terrestrial plant species and planetary balance.
