Trees are incredible organisms. They’re one of the longest running examples of life on earth with some species predating even the dinosaurs. Ginkgos are sometimes referred to as ‘living fossils’ due to some ginkgo leaves being found in fossils that are over 200 million years old and are almost identical to modern tree leaves. They’re truly the silent guardians of our planet.
Beyond their beauty and grandeur, trees play a crucial role in maintaining ecological balance. One of the most fascinating aspects of trees is their ability to share resources. Through an underground network of fungal connections known as mycorrhizae, aka “woodwide web” as dubbed by German Forester Peter Wohlleben, trees can exchange nutrients and water, supporting one another in times of need. This symbiotic relationship demonstrates an incredible level of cooperation within forests, allowing stronger trees to aid weaker ones, ensuring the overall health and resilience of the ecosystem.
Trees are efficient at cleaning our air and producing oxygen. Through photosynthesis, trees absorb carbon dioxide and release oxygen, the essential ingredient for all aerobic life forms. A mature tree can absorb up to 48 pounds of carbon dioxide annually and produce enough oxygen to sustain two people. Additionally, trees act as natural air filters, trapping dust, pollen, and pollutants, thereby improving air quality. Their leaves and bark also absorb harmful gasses like sulfur dioxide and nitrogen dioxide, making urban environments healthier for their inhabitants.
Trees give us so much more than just cleaner air. They provide homes for countless animals, support biodiversity, and help manage the water cycle by regulating groundwater and preventing soil erosion. In cities, they offer shade and cooling, boost property values, and even enhance our mental health by creating beautiful spaces for us to enjoy. Studies have shown that the practice of “forest bathing”, simply existing in the presence of nature, can help us deal with the stresses and strains of urban living. Even 15 minutes of exposure to of walking in nature can lead to improved moods and reduced fatigue, confusion, depressive symptoms, and anxiety. Truly, trees are our planet’s unsung heroes, doing countless jobs that make life on Earth better for everyone.
