WWF’s Earth Hour kicked off in Fiji, then New Zealand and Australia, spreading eastward through the international time zones to Korea, China, Malaysia, the Philippines, Singapore, India, United Arab Emirates, across Russia, Africa and Europe – and of course arriving in the UK in style at 8.30pm Saturday night.
Instantly recognisable landmarks across the world in darkness for the hour included the Eiffel Tower, the London Eye and Big Ben, Times Square, Dubai’s Burj al Arab hotel, Grenada’s Alhambra, Rio de Janeiro’s Christ the Redeemer statue, Athens’ Acropolis, India Gate, Sheik Zayed Grand Mosque, the largest mosque in the United Arab Emirates, and the Sydney Opera House.
