WWF have a released a short film on YouTube of a couple of panda's getting cuddly, to publicise their upcoming Earth Hour campaign.
The campaign is geared towards ensuring that governments agree on an effective plan to combat climate change at the UN climate summit in Copenhagen this December.
The film, whose tagline reads, “Whatever you’re doing on March 28, make sure you sign up and switch off the lights”, features a humorous montage of a pair of pandas getting up to the everyday activities we all do – such as socialising, exercising and (at the end) romanticising. The implicit message is that whatever it is pandas get up to only a daily basis is in now under serious threat because of climate change.
It follows WWF’s long running scheme to encourage people to adopt pandas .
From 8.30 to 9.30 pm on Saturday 28 March 2009, around a billion people will switch off all their lights in an effort to convince the world’s leaders to get serious about climate change.
1180 cities and 80 countries, all around the world, have signed up to switch off, and many of the world’s most iconic buildings will plunged into darkness as a gesture of their commitment to reduce their carbon footprint. Nelson’s Column, the Eiffel Tower, Christ the Redeemer in Rio de Janeiro and the London Eye will all be taking part.
