The ongoing Diwali celebrations are expected to bring joy and cultural unity across India. However, the use of firecrackers during the festival may contribute to air pollution, particularly in urban areas like Delhi, which already faces high pollution levels during this time of year. Residents are advised to be mindful of air quality and take necessary precautions, especially those with respiratory conditions. Additionally, the increased use of firecrackers poses risks of injuries and fires, necessitating caution during festivities.
