Ecosystem benefits of urban trees: #1 – Air purification

One of the most crucial roles of urban trees is their ability to purify the air we breathe. Through the process of photosynthesis, trees absorb carbon dioxide (CO2) and release oxygen, helping to mitigate climate change.
Additionally, trees act as natural filters, trapping harmful pollutants such as particulate matter, nitrogen dioxide, and sulfur dioxide. Their leaves and bark capture these pollutants, improving air quality and reducing the risk of respiratory ailments for urban residents.
