Diwali is traditionally known as the Festival of Lights, where people would visit family and friends, light lanterns and diyas, and encourage values of love and cooperation. However, the document expresses concern that firecrackers are now overshadowing these traditions and values during Diwali celebrations. It notes that firecrackers can cause various health issues like respiratory problems, allergies, and hearing loss, especially in children, and also contribute to air pollution. The document encourages considering these problems with firecrackers before letting children light them.
