The urban forest canopy plays a major role in making our cities liveable.
According to Wikipedia "they filter air, water, sunlight, provide shelter to animals and recreational area for people. They moderate local climate, slowing wind and storm water, and shading homes and businesses to conserve energy. They are critical in cooling the urban heat island effect, thus potentially reducing the number of unhealthful ozone days that plague major cities in peak summer months."
