FAMOUS landmarks such as Buckingham Palace and the Eiffel Tower will fall dark next Saturday as the world's largest environmental event takes off.

World Wildlife Fund's Earth hour at 8.30pm on Saturday, March 30 will see people across the globe switch off lights as a visual display of their commitment to our planet.

More than from 100 MPs pledged their #VoiceForThePlanet to send the message that it is unacceptable to sit back and watch the destruction of nature, and to help inspire their constituents to make their voice heard this Earth Hour, by choosing to change something in everyday life that will help protect our planet.

Eddisbury MP Mrs Sandbach said: “Earth Hour gives a voice to people everywhere who want to raise awareness of some of the biggest environmental challenges we are facing.

"I hope that by adding my voice for the planet I can encourage my constituents to do the same.”

In the UK every year millions of people take part in Earth Hour joining hundreds of millions more around the globe.

Earth Hour has helped countries find solutions for the environmental challenges we face globally.

This includes influencing national climate policies, planting new forests in Uganda and banning plastic in the Galapagos.

The world’s biggest landmarks – such as the Sydney Opera House, Empire State Building, the Eiffel Tower, Buckingham Palace, and Edinburgh Castle – will switch off their lights.
