This Saturday at 8:30pm, Auckland's Sky Tower will go dark for one hour. The switch-off will officially mark the beginning of the World Wildlife Fund's Earth Hour. Recognised by 7,000 cities, the 'lights off' initiative first began nine years ago in Sydney and aims to create a global community for a sustainable future.
The theme of this year's Earth Hour encourages participants to fight global warming, with the tagline: "Use #YourPower to Change Climate Change at earthhour.org."
In 2014, 162 countries participated in Earth Hour making it the world's largest mass participation event in history. Earth Hour Blue was also launched last year, the first crowd funding and crowd sourcing platform for the planet. In 2014, it raised over $61,000 for various environmental efforts across the world.
For 2015, the promotional video features world leaders, including U.S. President Barack Obama, UN Secretary-General Ban Ki-moon, and international celebrities such as Emma Thompson calling for action against climate change to British indie rock band Bastille's hit single Pompeii.
