...he found that it was possible to change the entire global climate simply by turning the symbiotic efficiency up or down. The amount of carbon dioxide or oxygen in the atmosphere and global temperatures all varied according to the efficiency of mycorrhizal exchange. Based on Field's data, mycorrhizal fungi would've made a substantial contribution to the dramatic drawdown of carbon dioxide that followed the plant boom in the Devonian period.
Fungi are deft rangers in this wilderness, and can forage in a way that plants can't. By hosting fungi within their roots, plants gain hugely improved access to these sources of nutrients. They too get fed. By partnering, plants gain a prosthetic fungus, and fungi gain a prosthetic plant. Both use each other to extend their reach.
A mycelial network is map of a fungus's recent history and is a helpful reminder that all lifeforms are in fact processes, not things. The "you" of five years ago was made of different stuff than the "you" of today. Nature is an event that never stops.
"I think there's lots we can learn as humans from mycelium. You can't just go and close a road to see how the traffic changes but you can sever a connection in the mycelial network."
Researchers have begun to use network-based organisms like slime molds and fungi to solve human problems. The researchers who modeled the Tokyo train network using slime molds are working to incorporate slime mold behavior into the design of urban transportation networks.
The resurgence of trufficulture is exciting because it is a way to produce a cash crop from a forested landscape, and a way to direct private capital into environmental restoration. To grow truffles, you have to grow trees. You have to acknowledge that
the soil is full of life. You can't cultivate truffles without thinking at the level of the ecosystem.
