Espoo becomes the first city in Finland to replace fireworks with laser show when celebrating the New Year. The public demand for banning the use of fireworks is constantly rising in recent years in Finland, aiming to reduce the cases of injuries, air pollution and stress and anxiety in animals caused by fireworks.
