Air pollution has been smothering Bangladesh for years, causing deaths and damaging the environment and the economy. The country has the worst pollution in the world, according to global air quality reports.
Health experts say pollution is a silent killer, and the number of respiratory illnesses has increased tenfold in recent years.
Many living in the capital city wear masks when out in its streets, not just because of COVID-19 but also due to pollution.
Environmental experts say unplanned development, coal-run industries, brick kilns, and construction works have made the situation worse.
