They call it the biggest environmental event in the world – and it takes place around the world.

Once again iconic landmarks from the Eiffel Tower in Paris, France to the Vatican, to the Sydney Opera House in Australia were plunged into darkness as the lights went off for Earth Hour.

Some 147 countries or territories pledged to join the event this year, switching off lights for 60 minutes at 8.30 pm local time to send out a message about climate change.

Among several countries taking part for the first time this year were Libya and Algeria, while restaurants in the United States joined in too by inviting guests to enjoy a real candlelit dinner.
