Earth Hour was this weekend. Don't worry; if you have no idea what that is, you're not alone. Earth Hour is an hour where everyone participating uses no electricity. Yep, that means no lights, no TV, no computers...nothing. It can be very hard to do this, especially since it occurs at nighttime . But it's also a great way to help the Earth, even if it's just for an hour. Imagine; if all the world, all 7 billion people, turned off their electricity for one hour, we would definitely make a difference in the environment, as well as conserve energy.
The first ever Earth Hour was in 2007, in Sydney, Australia. After it happened (and went well; around 2.2 million people took part), they wanted to make it a national event: but internationally, cities were beginning to sign up to take part in the 2008 Earth Hour. Earth Hour has only continued to get bigger, with more and more cities worldwide participating.
The website, www.earthhour.org, gives a history of this; and also has other Earth-friendly challenges in which you can participate. There is also a website: www.beyondthehour.org, which talks more about participating countries and the history, and also why Earth Hour is so important. If you want to do Earth Hour, the next one is scheduled for March 29th, at 8:30. However, not using electicity for an hour or two is easy enough to do every week. If you want to make a difference, both participate in and out of Earth Hour by turning off your electricity, and spreading the word about Earth Hour. Maybe, someday, Earth Hour will be a time when the whole world turns off all their electricity and takes a moment to think about how they can help improve our planet.
