With my daughter earning a college degree in forestry and wildlife, I have learned a lot about trees and appreciate all they do for our earth. I am learning to see trees through her eyes and how extremely essential trees are to our very existence. The last Friday of April is Arbor Day, a day dedicated to planting and caring for trees. We recognize the importance of trees for their ecological and environmental benefits, such as air and water purification, climate change mitigation, and biodiversity protection.
Trees provide numerous health benefits to humans. Trees improve our air quality by absorbing toxins and releasing oxygen. Trees provide shade and cool the air through a process called transpiration. Trees also help by enhancing green spaces, which encourage outdoor activities and can improve cardiovascular health and reduce obesity. Trees can also improve our mental health. Spending time around trees and nature has been shown to reduce stress, anxiety and depression. Exposure to green spaces with trees can enhance mood, improve attention, and reduce behavioral problems, especially in children.
Trees benefit the environment in many ways, such as preventing floods by absorbing rainwater, which reduces runoff and soil erosion. Trees also provide habitats for various species, contributing to biodiversity and a healthier ecosystem. Trees help slow the progress of climate change by cooling the air. This can be especially important in urban areas, where buildings and pavement absorb and retain heat, creating heat islands which can be five to eight degrees warmer than surrounding areas.
You can get involved in celebrating Arbor Day by donating to tree-planting organizations or volunteering for an organization to plant trees locally. If you have the right space in your yard to plant your own tree, consider selecting a tree native to your area, to support the ecosystem and attract native wildlife. For Ohioans, this fact sheet describes native trees that enhance biodiversity. You can find native trees in local nurseries or by ordering through online sources or mail catalogs. There are many factors to consider in selecting the right tree and the right location. This brochure from the Ohio Chapter of the International Society of Arboriculture details proper tree planting steps. The Arbor Day Foundation also has guidelines and tips for planting trees.
With all these amazing, tree-mendous benefits, consider what you can do to support the planting of trees in your community and worldwide.
