Bosnian major towns joined on Saturday night the cities worldwide and turned the lights off on its main landmarks for an hour to mark the Earth Hour and call for global action on climate change.

The Old Bridge in Mostar went dark at 8.30 p.m., joining for the 12th time the global initiative of the World Wide Fund for Nature (WWF) called the Earth Hour hand in hand with over 2,000 globally-known landmarks from thousands of cities and towns in hundreds of countries, in the action against climate changes.

Many citizens of Mostar recognised the initiative and shut the lights down in their houses, demonstrating their awareness on climate changes.

Bosnian capital city of Sarajevo also joined the action.

The lights on one of the city’s main landmarks, the City Hall, went out at 8.30 p.m. for an hour.

Bosnia’s third largest city, Banja Luka, shut down the lights on the buildings of the City Administration, Modern Art Museum, Music Pavilion and in two main streets.

This year, the towns of Brcko, Prijedor, Visegrad and Doboj also supported the global action in a symbolic way.

The Earth Hour initiative was launched in 2007 in a lights-off event in Sydney, with an aim to encourage individuals, communities and businesses to turn off non-essential electric lights for one hour on a specific day at the end of March, as a symbol of commitment to the planet.

The event has grown to engage more than 7,000 cities and towns across 187 countries and territories to raise awareness for energy consumption and effects on the environment.
