The Empire State Building dimmed its lights and the Eiffel Tower went dark

The usually glittering nighttime majesty of the Empire State Building was set to "faint sparkle" in New York, while theaters on Broadway also toned down the neon. Millions of people around the world were taking part in the annual Earth Hour organized by conservation group WWF, with a string of well-known sights plunging into darkness globally. The famous Las Vegas strip went dim, with the replica Eiffel Tower at Paris Hotel turning its lights off, along with several hotels and casinos that normally illuminate the main drag in Sin City.
