Trees talk to each other through a secret underground internet. Mother trees feed their babies. The forest is one big group chat. How much of that is real? Maya and Theo dig into the mycorrhizal networks wiring forests together — and find the truth is a market, not a charity.
In this episode:
• The 450-million-year trade deal: arbuscular vs. ectomycorrhizal fungi, sugar for phosphorus and nitrogen
• One fungus, nineteen trees: the DNA-mapped network in a B.C. old-growth forest
• Simard 1997: labeled CO2, plastic baggies, nine days — carbon moving both directions
• The mother-tree story and the 2023 audit: zero published evidence for kin preference
• It’s a market, not a charity: reciprocal rewards, cheaters, and sanctions
• The aphid experiment: beans, wasps, and defense by underground proxy
• Mushroom “language”: fifty words of hype vs. “they are saying nothing”
• Planetary numbers: a third of humanity’s carbon through fungus, 68 quadrillion miles of thread — densest under grasslands, not rainforests
Field Notes: find the biggest, oldest tree near you and stand under it — you’re standing on a network. Take a photo of the unphotogenic part: the soil, the grass, the base of the trunk.
