A few days ago, we stumbled upon a revelation, something that might seem obvious to some, but we couldn’t wait to share it with you. It’s the incredible lesson trees offer us, reminding us how deeply our surroundings and the company we keep shape our lives.
It’s fascinating to see how trees have their own hidden network, often called the “Wood Wide Web.” With the help of mycorrhizal fungi, which cling to their roots, they create an underground web that lets them share water, carbon, nitrogen, and chemical signals.
In the same way, trees show us the value of having mentors or guides. Older trees support the younger or weaker ones, sending them sugars, nutrients, and water. This beautiful behavior has been observed in the forests of firs, birches, and pines right here in Canada.
But that’s not all. When a tree is attacked by insects, it sends out an instant warning to others nearby, up to 30 or 40 meters away, without any root connection. It releases chemicals into the air, signaling others to brace for a potential attack by activating their defenses, like producing bitter leaves to ward off pests.
Once again, nature teaches us a profound lesson. It shows us the importance of choosing where to plant our roots, who to lean on, and whose warnings to heed. Unlike trees, we have the freedom to move and put down roots in more fertile ground. In the end, it’s up to us to decide who we surround ourselves with.
