How does planting trees in cities contribute to urban sustainability, as suggested by a recent study?

Planting trees in cities contributes to urban sustainability by providing numerous environmental, social, and economic benefits. Trees help improve air quality by absorbing pollutants and producing oxygen, reduce urban heat island effect by providing shade and cooling the air, and mitigate climate change by sequestering carbon dioxide. Additionally, trees enhance biodiversity, reduce stormwater runoff, and improve mental health and well-being. Overall, the recent study suggests that planting trees in cities is a cost-effective and efficient way to promote urban sustainability.
