More than 2,100 cities across the world have pollution exceeding the recommended levels of particulate matters, according to a new report published on Monday. These represent more than 70% of the 2,971 cities in the WHO’s air pollution database. Particulates are products of fuel consumption that are small enough to get into the respiratory tracts of humans. These are associated with a wide range of respiratory disorders due to the significant potential for harm the particulates contain. When fossil fuels such as coal, petrol, or diesel are burnt, they produce these particulates as a key byproduct, which has accelerated the rise of pollution-related problems in developing countries where the rapid growth of the economy has created various new emission channels. Medical journal Lancet published the report.
The report says 44 cities in the U.K. exhibit pollution levels exceeding the recommended levels, showing the problem is as widespread as it is threatening. While the economic and environmental effects of pollution have been debated ad nauseam, the report focuses on the health effects of climate change and pollution, calling climate change the major health threat of the 21st century.
More than 800,000 deaths in 21 Asian countries in 2015 were caused by pollution-related problems, including the large-scale use of coal for power generation and the growing use of fossil fuels in transportation.
Apart from respiratory concerns, air pollution and the resultant climate change has also resulted in an increase in the prevalence of diseases such as dengue, as the mosquitos carrying the disease are now able to breed in more countries than before due to rising temperatures.
