Why we need trees

Trees don't just make the city look pretty, they have a real environmental function. They control the greenhouse effect: when heat rises from the tar, trees act as a natural coolant.

Carbon dioxide emitted from cars is taken in by trees and converted into oxygen.

An acre of trees, on average, can store 2.6 tons of carbon (pollution) annually and generate enough oxygen daily for 18 people.

A mature leafy tree produces as much oxygen in a season as 10 people inhale in a year. In city areas without tree cover, streets and parking lots can raise air temperatures to 35 degrees Celsius. Such "heat islands" can cause cities to be five to nine degrees warmer than surrounding areas.

Trees also reduce noise levels.
