Armenia will observe Earth Hour 2013 tonight. Millions of people across the globe will turn off their lights for 60 minutes on Saturday night starting at 8:30pm local time in a symbolic show of support for “Earth Hour” campaign against climate change.
Earth Hour is a worldwide event organized by the World Wide Fund for Nature (WWF) and held towards the end of March annually, encouraging households and businesses to turn off their non-essential lights for one hour to raise awareness about the need to take action on climate change.
The event first took place in 2007, when 2.2 million residents of Sydney participated by turning off all non-essential lights. Following Sydney’s lead, many other cities around the world adopted the event in 2008.
Many of the world’s most iconic attractions, including Sydney Opera House, the Empire State Building and the Eiffel Tower will take part.
Last year more than 150 countries participated in the event which saw some of the world’s most iconic landmarks dim, and this year the movement has spread to Palestine, Tunisia, Suriname and Rwanda.
