Bulgaria, World Prepare to Switch Off for Earth Hour
Bulgarians and people around the world are preparing to observe the global initiative Earth Hour by switching off their lights for one hour on Saturday.
The Earth Hour is a worldwide movement for protection of the environment and raising awareness for the dangers of climate change, organised by the World Wide Fund for Nature (WWF).
It encourages people around the world to show their commitment to the planet by switching off all non-essential lights for one hour between 20:30 and 21:30 local time on the last Saturday in March.
It started as a lights-off event in 2007 in Sydney, but since then it gathered millions of followers, encompassing individuals, households, communities and businesses around the world.
Earth Hour has been observed in Bulgaria since 2008 and this year's edition is dedicated to the Bulgarian rivers.
This year the tagline for the global campaign is "Change Climate Change", which returns the movement to its original focus to initiate citizen action on global warming.
Over 170 countries and territories have confirmed their participation, among them 1200 landmarks and iconic buildings and nearly 40 UNESCO world heritage sites.
