Ferris Jabr, author for the New York Times Magazine, explores the revolutionary research of ecologist Suzanne Simard, who challenges old views of forests as competitive arenas. Instead, she reveals the cooperative nature of trees through underground fungal networks that promote sharing and nurturing. The discussion delves into the roles of 'mother trees' and the complex interconnections critical for forest health, ultimately highlighting the symbiotic relationship between trees and humanity, especially in the face of climate change.
