Earth Hour

To say that Earth Hour is merely a holiday would be grossly underestimating its impact and scope. Earth Hour is a worldwide one-hour event that occurs every year near the end of March. The purpose of this hour on this day is to unite people all across the globe in their effort to save the planet. This event was created by the World Wide Fund for Nature (WWF) and encourages people to turn off their non-essential electric components as well as their lights.

The WWF hopes that if people practice this event for that one hour per year, they will think about their energy consumption more and make an effort to use less energy.

The History of Earth Hour

The event was originally started in 2007 in Sydney, Australia. However, once it was observed in that city, it quickly spread across the rest of the world. It’s now observed in thousands of different towns and engages millions of supporters. In 2013, Argentina used Earth Hour to get a bill passed in their Senate that would protect over 3 million hectares of marine area.

On Sunday, March 29, 2015, 172 countries participated in the event and switched off the lights on over 10,000 of the most iconic landmarks for one hour. That year also saw almost 50,000 different celebrations all over the world – all bringing attention to climate change and the need for energy reforms.

Earth Hour Customs & Traditions

On Earth Hour, everyone who is participating turns off their lights and other electric devices for one hour. However, this isn’t the only way the event is celebrated. It is also celebrated by participants raising attention to ecological-based problems such as pollution and climate change.

This is done by using Twitter, Facebook, and other social media sites to get the word out to as many people as possible. Participants are encouraged to not only use social media to advance these causes but also to actively take a hands-on approach to the problems facing this planet.
