Smog Returns to Delhi

Deadly smog has returned to Delhi. Air pollution reached several times the level suggested by the World Health Organisation. People were told to stay indoors and not walk on the streets of the world’s most polluted city. Doctors declared a state of emergency and some schools in the city stayed closed.

Smog in northern India is a big problem, especially during the winter months. From November to March cold temperatures force pollutants and dirt particles closer to the ground, mixing with the foggy air. Low wind speeds and dust from construction sites have also contributed to high pollution levels in the area.

Environmentalists say that factories and traffic are the biggest causes of smog. In addition, farmers in northern India burn the leftovers of crops after harvest and therefore produce more smoke.

Critics say that Indian government is not doing enough to protect India’s second-largest city. New measures took effect last October. Traffic became more regulated and several power plants were shut down. Authorities also want to restrict the personal use of cars to every second day, a measure that already worked in the past.

Last November Delhi was hit by the highest air pollution levels in 20 years, forcing over a million children to stay at home. Researchers claim that 2.5 million Indians die of pollution every year.
