The United Nations declared 2010 to be the International Year of Biodiversity. It is a celebration of life on earth and of the value of biodiversity for our lives.

Earth Hour is to take place in 92 countries, surpassing last year's record. 17 new countries and regions are ready to switch off for the first time.

Blake's track, Beautiful Earth, has been announced as the anthem for WWF's Earth Hour in the UK.

Out of the 8,766 hours in a year, let us give one back to the earth.

Earth Hour will be observed globally between 8.30 - 9.30pm local time on Saturday 27th March 2010.

It is a call to stand up, to take responsibility, to get involved and lead the way towards a sustainable future.
