Researchers from the Energy Policy Institute at the University of Chicago in the United States have found the main cause of very low life expectancy in Nigeria and five other countries.
The main cause, according to the researchers is air pollution, with an alarming 99% of the world said to be breathing toxic air.
Life expectancy in Nigeria is 55.44 years, whereas in Niger it is 61.45 and South Africa 65.25
While developed nations have some infrastructure to deal with air pollution, countries in Africa and Asia do not have.
In the annual Air Quality Life Index report published Tuesday, the researchers said much of the air pollution that impacts life span originates in Africa and Asia, which reportedly contributes to more than 92% of the global life expectancy loss.
“Three-quarters of air pollution’s impact on global life expectancy occurs in just six countries, Bangladesh, India, Pakistan, China, Nigeria and Indonesia, where people lose one to more than six years off their lives because of the air they breathe,” Michael Greenstone, Air Quality Life Index creator and Milton Friedman Distinguished Service Professor in Economics, said in a statement.
Bangladesh, for example, which has the most air pollution, averages a loss of 6.8 years of life.
According to the researchers, those regions — where air pollution is now as great of a threat to public health as HIV/AIDS and malaria — lack the appropriate infrastructure to address air quality.
Air pollution reduces the average life span globally by 2.3 years, making it the “greatest external threat to human life expectancy,”
The researchers said the effects of merely inhaling unclean air were comparable to smoking, but caused over three times the damage of alcohol use or unsafe water and over 5 times that of car crash injuries.
In 2021, 20 of the 30 most polluted US counties were located in California, likely due to the state’s wildfires where some residents are regularly exposed to high levels of fine particulate matter, which measure at or below 2.5 microns, which has been linked to an array of health consequences that affect the brain and lungs.
In the same year, not one country met the World Health Organization’s air quality standard of 5 micrograms of pollutants per cubic meter of air (μg/m³).
