A number of prominent public buildings across Ireland were plunged into darkness last night as part of Earth Hour.
Millions of people in 7,000 towns and cities across the world turned out the lights at 8.30pm.
Earth Hour is a global initiative which began in Australia in 2007. It aims to highlight the need for action to tackle the world's environmental challenges, including climate change. Last year hundreds of millions of people worldwide switched off their lights for one hour to demonstrate their support for the protection of the environment.
Landmark buildings including Sydney Opera House, the Bird's Nest in Beijing, the Eiffel Tower, The Empire State Building, Niagara Falls, and Los Angeles Airport will go dark tonight in a show of solidarity.
