World Wide Fund for Nature Malaysia (WWF Malaysia) is urging all Malaysians to come together again during Earth Hour 2010 to show their support for the fight against climate change.

The public is asked to switch off all non-essential lights between 8.30pm and 9.30pm on March 27.

Climate change is a threat not only to humans but wildlife and nature as well, a WWF-Malaysia statement here says.

Climate change will badly affect turtles, one of Malaysia's most endangered species, due to increased frequency of storms that will erode beaches and reduce their nesting habitats, it says.

"The temperature of the nest determines the sex of the hatchlings. Warmer nests produce mostly female hatchlings.

"As the climate warms, it is predicted that turtle nests too will be warmer, resulting in fewer male hatchlings.

"This situation will have an adverse impact on future turtle populations," it adds.

Over six million Malaysians participated in Earth Hour 2009.
