Trees are fascinating organisms that play a crucial role in sustaining life on Earth. They can live for thousands of years; the oldest known tree, a bristlecone pine named Methuselah, is over 4,800 years old. Trees communicate through an underground network of fungi, often called the "Wood Wide Web," sharing nutrients and warnings about pests. One large tree can absorb up to 48 pounds of carbon dioxide annually and provide enough oxygen for four people. The world’s tallest tree, a coast redwood named Hyperion, stands over 380 feet tall. Trees also reduce stress and promote well-being in humans through their calming presence.
