sad tree stumps

Trees reduce temperatures by shade and transpiring water. This helps reduce air conditioning bills and energy use. Studies have even proven that one mature tree can produce the same cooling effect as 10 room-sized air conditioners. This becomes an effective tool in reducing urban heat islands and hot spots in cities.
Research has also shown a 60% reduction in particulates from car exhaust fumes on streets lined with trees. (smart cities)
"One morning I walked down my street and saw that a tree has been cut down and someone drew a lot of sad smiley faces on the cut stumps. Somehow this deeply resonated with me. I felt less alone with my own feelings and decided to make sure that in future I am always carrying a sharpie with me."
