THE world is to be plunged into darkness this weekend as people turn off their lights to mark World Nature Foundation's (WWF) Earth Hour.

At 8.30pm on Saturday, March 28, hundreds of millions across the globe will unite to show they care about the future of the planet, as they dim their lights for an hour.

Supporting the WWF Cymru campaign, AM Joyce Watson said, “I am proud to support WWF’s Earth Hour, to be part of such an inspiring global event.

“Last week we were lucky enough to experience the partial solar eclipse. It was a moving reminder of our place in nature and how precious our planet is. Everyone can make a difference to help protect it for future generations. I urge everyone to sign up to Earth Hour online and switch off their lights at 8.30pm on March 28.”

Anne Meikle, Head of WWF Cymru, added: “I’m delighted that Joyce is supporting Earth Hour. It’s vital that our National Assembly has a key role to play in leading by example on protecting the environment. Please sign up for Earth Hour and switch off on the night.”

This year supporters in Wales are encouraged to mark Earth Hour with a candlelit dinner either at home or in a participating restaurant. Welsh venues and individuals will join thousands of iconic landmarks across the world in turning out the lights. Key Welsh sites such as the Senedd and Caerphilly Castle will take part, along with Welsh universities like Swansea and Bangor universities. Over half of all Welsh local authorities have already signed up to Earth Hour, including Carmarthenshire, Conwy and Cardiff councils.

WWF’s Earth Hour started in Sydney, Australia, in 2007. Since then more than 7000 cities and towns worldwide have taken part in the annual event.
