Dear MEL Topic Readers,
21 of the world's 30 cities with the worst
air pollution are in India
As many as seven million people die each year
because of air pollution, according to the World Health Organization, WHO. South
Asia has the most air-polluted cities with 27 of the 30 most polluted cities in
India, Pakistan or Bangladesh. For example, the air quality index level of New
Delhi, the capital of India, was more than three times the
"hazardous" level.
Exposure to small particles, which are
smaller than 2.5 micrometers in diameter, are called PM 2.5 and could cause
lung and heart disorders and also damage cognitive and immune functions. Rapid
urbanization and moralization are to blame for the poor air quality in those
major cities. Also, burning coal to generate power, cook meals, and warm houses
pollute the air. While large cities in the most populous country, China, have been improving
the air quality, those in the second-most populous country, India, have poor air
quality as 21 of which are ranked within the world’s top 30 air-polluted cities.
What is it like to live in such cities?
