On March 23, cities worldwide dimmed their iconic landmarks for Earth Hour, a global movement to raise awareness about climate change. Australia's Sydney Opera House, along with the Harbour Bridge and other structures, embraced darkness. Across Asia, Hong Kong's Victoria Harbour and Tokyo Tower joined the initiative, with nearly 4,000 entities participating in Hong Kong alone. In Europe, Greece's Parthenon Temple and London's Piccadilly Circus dimmed their lights, while Paris' Eiffel Tower remained dark for seven minutes. Barcelona's Sagrada Familia cathedral also participated, reflecting the event's global reach and growing importance in addressing environmental issues. #effieltower #tokyotower #earthhour #australia #japan #france #greece #india #spain #newyork #worldnews n18oc_world n18oc_crux CRUX is your daily video news guide to the big events that are shaping our world.
