trees have always been an essential part of successful cities

We may think of nature as being unconnected to our urban spaces,but trees have always been an essential part of successful cities.Trees act like a natural sponge,
absorbing storm water runoff before releasing it back into the atmosphere.The webs of their roots protect against mudslides while allowing soil to retain water
and filter out toxins.Roots help prevent floods,while reducing the need for storm drains and water treatment plants.Their porous leaves purify the air by trapping carbon and other pollutants,
making them essential in the fight against climate change.
