The 3 dirtiest countries in the world

India:
India has faced numerous environmental challenges, including air pollution, water pollution, inadequate waste management, and deforestation. Rapid urbanization and industrialization have contributed to poor air quality in major cities like Delhi, which is notorious for its high levels of particulate matter and smog. The Ganges River, one of India's most sacred rivers, is heavily polluted due to industrial effluents and untreated sewage.

Bangladesh:
Bangladesh faces similar environmental challenges to India, including air pollution and water pollution. Dhaka, the capital city, has been ranked among the most polluted cities in the world. Water pollution is a significant issue due to the discharge of untreated sewage and industrial waste into rivers. Additionally, Bangladesh is vulnerable to climate change, with frequent flooding and cyclones affecting the country.

China:
China has made significant economic progress in recent decades, but it has also faced environmental consequences. Air pollution in many Chinese cities, particularly Beijing, has been a major concern. The country has experienced problems with smog, caused by high levels of industrial emissions and coal consumption. Water pollution is also a significant issue, with numerous water bodies suffering from contamination due to industrial and agricultural runoff.
