The Underground Fungal Network Map
Monday 15th June, 2026
The Society for the Protection of Underground Networks led a study mapping arbuscular mycorrhizal fungi across the world, estimating that their threads stretch 110 quadrillion kilometres. The striking scale comparison — enough thread to reach the Sun hundreds of millions of times — gave journalists a memorable way into research about soil ecosystems and the pressures threatening them.
Why it worked: It nailed a shock-scale stat (110 quadrillion km to the Sun hundreds of millions of times) grounded in peer-reviewed, global data and vivid visuals.
The lesson: Consider framing your pitch around one audacious, arithmetic-backed comparison plus an interactive map from original measurements, not anecdotes.
