Answer:
The
'Earth Hour' is one hour during the year at night when all lights are switched
off to conserve electrical energy and reminds everybody that resources are
limited and we should conserve them. WWF already tackles many environmental
impacts- deforestation, endangered species and the impact of climate change.
But 'Earth Hour' is a chance for everyone to say they'll do their bit.
And that's never been more vital. WWF in the United Kingdom promoted Earth Hour
2012 with the tag line, "Our World is Brilliant". Imagery on the
Earth Hour website, posters, videos, e-cards and brochures promoting world-friendly
dining featured the image of a fluorescent environmental friendly globe.
The branding effort is focused on connecting people with
the global phenomenon in which hundreds of millions of people turn off their
lights for one hour, on the same night, all across the planet. It's always a
night to remember, whether it's a special candlelit evening at home with
friends or family, or a night out on the town or watching the spectacular
global switch offs from landmarks like the Eiffel Tower, the Pyramids of Giza,
Times Square, Sydney Opera House and so on.
