Dear Mehdi;

Trees play a critical role for people and the planet. Numerous studies have demonstrated that the presence of trees and urban nature can improve people's mental and physical health, children's attention and test scores, the property values in a neighborhood, and beyond. Trees cool our urban centers.

Trees promote health and social well‐being by removing air pollution, reducing stress, encouraging physical activity, and promoting social ties and community. Children with views of trees are more likely to succeed in school. Trees promote a strong economy and can provide numerous resources to the people that need them. While cities are getting hotter, trees can reduce urban temperatures. They provide habitat and food for animals. Finally, trees are valuable green infrastructure to manage storm water. Money spent on urban forestry has a high return on investment ,and more.

I think that there are several approaches to using plants in an urban context. One important approach is environmental. But for me, I think using plants as barriers, or a space organizer is the most important.

Dear Usama Badawy Thank you for your complete answer.

Dear Samir Al Qeisi Thank you, I agree with you.
