SINGAPORE - The Earth Hour global movement to help fight climate change is going beyond asking people to turn off their lights to making firm commitments to protect the environment, organizers said on Wednesday.

"This year, Earth Hour asks people to commit to an action, big or small, that they will sustain for the future of our planet," organizers said in a statement issued in Singapore.

Among the actions announced on Wednesday is a commitment by the Nepalese government to put an end to tree-felling in the Churiya range, a 23,000 square km forest area.
