`Earth Hour' will be observed by India as well as by the rest of the world to save energy as well as environment on March 28. The people will be observing the Day by switching off all the lights and electrical appliances for an hour from 8.30 pm to 9.30 pm. This year India, especially Delhi and Mumbai will participate. Lights would be switched off or dimmed at 11 PVR cinemas in Delhi and Mumbai and corporate offices. As per World Wide Fund for Nature (India), this year 50 lakh citizens of 377 cities from 74 nations are participating in this initiative.
Began with one hour switching off lights at Sydney in Australia two years back, the `Earth Hour' was observed in 35 countries last year in an attempt to reduce the carbon footprint. Earth hour is not about a quantitative measure about saving electricity but a powerful symbol for the fact that its possible to take action against climate change. It is to bring about awareness about the increasingly growing problem of climate change and to subsequently make changes in lifestyle that lead to wiser energy use.
