Trees are secretly talking, trading and waging war on one another. They do this using a network of fungi that grow around and inside their roots. The fungi provide the trees with nutrient, and in return they received sugars. But scientists have found this connection runs far deeper than first thought. By pinging into the function network, trees can share resources with each other. The system has been nit named woodwind web. It's thought that older trees, fondly known as mother trees, use this fund network to supply shaded seed dings with sugars, giving them a Better chance of survival. Those trees that are sick or dying may dump of their resources into the network, which might then be used by healthier neighbours. Plants also use fungi to send messages to one another. If they are attacked, they can release chemical signals through their roots, which can warn their neighbours to raise their defenses. But like our internet, the woodwives web has its dark side too. Some all kids hacked the system to steal resources from nearby trees and other species, like the black walnut, spread toxic chemicals through the network to sabotage their rivals. Our bori al cybercrime as side scientists are still debating, White plants seem to behave in such an altruistic way. The hidden network creates a thriving community between individuals. When you're next in woodland, you might like to think of trees as part of a big superorganism, chatting and swapping information and food on the your feet. oh. No, another forest has been cut down to build her down. Humans can't keep cutting trees like this. Well, that's an issue we dress in today, is by answering a crucial question, what if all trees were cut down? Zoom in. Trees are a lifeline, not only because they produce paper, timber and twin gum, but because they serve an important role in the oxyde cycle food chain, and even serve as a shelter for many living beings, including humans. But sadly, we often treat trees as something to be harvested for economic gain, or as an inconvenience in the way of human expansion. Yes, you won, believe. But since humans began practicing agriculture around twelve thousand years ago, we have chopped down nearly half of the world's estimated five, five, eight trillion trees, leaving us with only three trillion of them at this point in time. That's not IT. Even today, we are cutting down fifteen billion trees each year. And if we continue at this rate, trees will go extinct in the next two hundred eight years. Once that happens, life as we know IT today will take a tragic time, and the world will remain nothing but a parent. gasoline.
