Washington: The Empire State Building and United Nations headquarters in New York joined other iconic buildings and monuments around the world plunging into darkness for sixty minutes on Saturday to mark Earth Hour and draw attention to climate change.
The Eiffel Tower, the Kremlin, the Acropolis in Athens and Sydney's Opera House also dimmed their lights as millions of people from some 170 countries and territories were expected to take part in Earth Hour, the annual bid to highlight global warming caused by the burning of coal, oil and gas to drive cars and power plants.
The event, which originated in Sydney, has grown to become a worldwide environmental campaign, celebrated across all continents.
