Millions of people switched off their lights at 8.30 pm local time across many countries around the world on March 29, Saturday, to mark the annual Earth Hour of WWF.
This is the eighth year, and the event has got response from numerous countries and people in the world, who have supported Earth Hour for environmental issues.
In line with the event is the announcement of the latest report by Intergovernmental Panel on Climate Change, on global warming and its effects, which is expected to release on Monday in Japan.
Both events are massive as IPCC’s report will talk of how global warming is going to affect water, weather, wildlife and food supplies in years to come.
To mark the Earth Hour of 2014, celebrated landmarks of the world will dim and turnoff their lights. This includes the Eiffel Tower in Paris, Empire State building in New York, the Burj Khalifa in Dubai, and the Red Square in Moscow among others.
UK too celebrated Earth Hour as the Buckingham palace, the Houses of Parliament and the London Eye lowered their lights.
Started in 2007, Earth Hour has become the biggest environmental event of the world, with a record of 154 countries taking part in 2013.
However, this year is special as Earth Hour Blue is launched by WWF with the aim of raising funds and taking actions with digital participation from users for a range of environmental issues.
Current projects include reduction of human-wildlife conflict in India through a solar-lighting project and aiding Philippines fishermen to build boats without wood.
