Earth Hour tonight!

At 8.30pm, people, businesses and important buildings around the world will switch off their lights for an hour – WWF’s Earth Hour. Who will be involved? Nelson’s Column, the Forth Bridge, the Millennium Stadium in Cardiff, the Eiffel Tower, Niagara Falls, Christ the Redeemer in Rio de Janeiro, Table Mountain in Cape Town and Sydney Opera House. The London Eye, too, will be switched off for the hour. Even the pyramids in Egypt are to be plunged into darkness for an hour.

A little disappointing to see our authority hasn't signed up - lets just hope it is an oversight! Time yet. See the WWF site for more info and the films below.

Here’s the Birds nest stadium in Beijing 2009 as a starting point.

This shows how this idea is now global.

Join in with this and support the world tackle global warming.
