What is one ecological benefit of planting trees in urban areas?

Planting trees in urban areas provides a significant ecological benefit by improving air quality and providing shade. Trees absorb carbon dioxide and release oxygen, contributing to cleaner air. They also filter pollutants from the air, such as sulfur dioxide and nitrogen oxides. By releasing moisture through a process called transpiration, trees help cool the surrounding environment, offering shade that can reduce the urban heat island effect. This cooling effect can lower energy consumption by reducing the need for air conditioning, leading to further reductions in air pollution from power plants.

Furthermore, the shade provided by trees can enhance the comfort of public spaces, encouraging outdoor activities and promoting a healthier urban lifestyle. Through these mechanisms, trees play a crucial role in creating a more sustainable and livable urban environment.
