While-listening Post-listening Good evening. Thanks for joining me in this week’s The Natural World. I’m Rebecca. For the next four weeks, we’ll talk about trees around us. And today's topic is about how trees help each other. Being a tree can be difficult, but trees have found ways to make it easier for one another. In fact, trees are not alone. They have very long roots, and they use them to communicate with their neighbors. When something bad happens to a tree, it may be able to send a message through its roots. Then the other trees will try to help it. Did you know that, like us, trees also have families? Older trees give younger trees food and water. Younger trees also help older trees survive. When one tree becomes ill, the healthy trees around it will try to help. Most trees only share things with trees from the same species. However, some trees always help their neighbors, even if they aren’t their relatives. Trees know they are stronger together. When their branches and leaves join together, they don’t need to worry about strong winds. Together they grow better and stronger. Aren’t trees amazing? That’s all for today. Next week I’ll talk about famous trees in China. What are they? Think of your favorite and join me next Tuesday to find out more. See you then!
