Did you know that trees have their own secret communication network? Through a vast web of fungi, they can warn each other of potential threats, like a underground internet. But that's not all - the world's largest living organism is actually a fungus covering over 2,200 acres in Oregon, USA. Our forests are home to a staggering 80% of the world's biodiversity, with a single tree supporting up to 1,000 different species. And let's not forget the Amazon rainforest, responsible for producing a whopping 20% of the world's oxygen. The natural world is full of fascinating secrets, and it's time we start listening to the whispers of the trees.
