The rapidly increasing populations of cities and urban centers alter ecosystem services such as water, air and land cover, with disastrous impacts on health and wellbeing, particularly in megacities. In 2015, polluted air was estimated to have been responsible for 6.4 million deaths worldwide, and it is projected that it will cause between 6 and 9 million deaths per year by 2060. In 2017, outdoor air pollution resulted in 1.2 million deaths in India and brought about a 3% loss in GDP. The increase in population, vehicles, and industries has led to changes in land use and land cover and a rise in city temperatures and air pollution, creating urban heat islands (UHIs). Together, UHIs and air pollution have damaging impacts on human health that range from stress and headache to asthma, bronchitis, and chronic diseases, and even to death. weiterlesen
