According to the University of Washington's Center for Urban Horticulture, mature tree canopies reduce the air temperature of urban areas between five and 10 degrees Celsius. Imagine replacing these ecological services with human-built substitutes. While we can handle cooling a building, creating city-sized air conditioning that could reduce the temperature of an urban area by 10 degrees is an engineering feat that would require massive amounts of energy.
