According to a recent report, only seven countries worldwide met safe air pollution levels in 2023.

The global air pollution crisis is alarming scientists who describe it as a global health catastrophe. The report analyzed data from over 30,000 monitoring stations across 134 countries, and it revealed that fine particulate matter (PM2.5) levels exceeded safe limits in most regions. Among the seven countries that met safe air quality guidelines were Australia, Estonia, Finland, and New Zealand, with Iceland having the cleanest air in Europe. While some European countries showed improvement, many still face significant pollution challenges.

The countries with the worst air quality were concentrated in South and Central Asia, home to the top 10 most polluted cities in the world. Bangladesh came first, with PM2.5 more than 15 times higher than the WHO annual guideline. The other countries with the worst air quality were Pakistan, India, Tajikistan, and Burkina Faso. Canada was the most polluted country in North America.

It is necessary to deal with this issue to ensure public health and reduce its negative effects on society.

Difficult words: fine particular matter (tiny pieces of solid matter or liquid that people can inhale), guideline (a general rule or piece of advice).
