Deep in the heart of Oregon, USA, lies a secret network that's been buzzing with activity for centuries. Meet the world's largest living organism, a fungus that spans over 2,200 acres, connecting trees in a silent, underground conversation. When one tree senses danger, it sends a warning signal through the fungal highway, giving its neighbors a heads up to boost their defenses. It's a forest-wide whisper network that's been keeping trees one step ahead of threats for millennia. And did you know that forests like this one produce a whopping 28% of the world's oxygen? Mind blown yet? Just think of the towering coast redwood, Hyperion, standing tall at over 380 feet – a true giant in this intricate web of life.
