The United Nations is calling for a significant increase in the number of trees in cities and towns, highlighting their multifaceted benefits. Trees contribute to cooling urban temperatures by 2-8 degrees and play a crucial role in removing pollutants and fine particulate matter from the air.Each tree absorbs and stores approximately 150 kg of carbon dioxide annually, aiding in the fight against climate change. In addition to their environmental impact, trees provide vital habitats for birds and support urban biodiversity.The UN also emphasizes the mental and physical health benefits of green spaces, noting that relaxing near trees can reduce stress and enhance overall well-being. The promotion of increased vegetation in urban areas is seen as a key strategy for improving environmental quality and public health.
