Earth Hour is organized by WWF. With almost 5 million supporters and a global network in over 100 countries, it's one of the world's largest and most respected independent conservation organizations. WWF's mission is to stop the degradation of the Earth's natural environment and build a future where people live in harmony with nature. Earth Hour started on March 31st, in 2007 in Sydney, Australia when 2.2 million individuals and more than 2,000 businesses turned their lights off for one hour to take a stand against climate change. Only a year later Earth Hour had become a global movement with more than 50 million people across 35 countries participating. Global landmarks such as the Sydney Harbour Bridge, CN Tower in Toronto, Golden Gate Bridge in San Francisco, and Rome's Colosseum, all stood in darkness, as symbols of hope for a cause that grows more urgent by the hour. In March 2009, hundreds of millions of people took part in the third Earth Hour. Over 4,000 cities in 88 countries officially switched off to pledge their support for the planet, making Earth Hour 2009 the world's largest movement to stop global climate change. On Saturday 27 March, Earth Hour 2010 became the biggest Earth Hour ever. A record 128 countries and territories joined the global display of climate action.

These days, if you still think the cellphone is just for talking, you will get laughed at. Yes, it's true, voice-only handsets have become out of date. Today's do-it-all mobiles have a lot in common with the computer. The only difference may be that they fit in your pocket and you pay by the minutes to use them. Some of the things a cellphone can do for you will be available this year: Surf at speed Cellpones that let you use the Web have been around for years. So, what's new? Well, faster third-generation(3G) net works let you surf at anywhere. This then allows a carrier to send video, music, and games to your phone. Possible choices are from LG Electronic VX 8000 and Motorola V 1150. Listen as you go The problem with most cellphone MP3 players is that they hold only a handful of songs. But, that's about to change. Sony Ericsson's new W800i can hold around 150 songs in its 500 MB memory. And Sumsung's SPH-V5400 even comes with a 1.5 GB hard drive. Mobile phones may eventually replace mini-MP3 players, especially for teens. Say cheese Camera cellphones are not new either. But, most of them have limitations: around 1-megapixel . But new technology has made 2-megapixel units more common and 3-megapixel units are showing up soon. Some 2-megapixel models, like Sony Ericsson's K750i, offer limited zoom and focus controls. Others, like LG's recent MMA7110, can even capture 30 minutes of full- motion video. Portable TV You say you like "watching TV"? That's what Sumsung MM-A700 wants to give you. The new model lets users watch popular TV programs--for a fee. Other choices are Nokia's 6620, Sanyo's MM 7400 and NEC's N940.The NEC model lets you watch public TV--no fee. The above are just a handful of what you will see in the coming months. Further down the road, your mobile phone may play a host of other roles, such as mobile credit card, position locator...
