That was the message from Prime Minister Helen Clark, as she spoke about the importance of small individual actions in fighting climate change, officially launching Earth Hour in Christchurch at Christchurch Art Gallery Te Puna o Waiwhetu.
"Events like Earth Hour Christchurch are important because they raise awareness of the worldwide sustainability challenge. It also shows how we can all make a difference, and how, when we work together, our small actions can have a big collective impact," said Helen Clark.
The Prime Minister was guest of honour as Christchurch's business and community leaders gathered to celebrate their city's commitment to Earth Hour, which will see the lights of the city go out for one hour on 29 March at 8pm.
Speaking at the launch, the Prime Minister praised Christchurch for taking a stand on climate change and becoming the first city in New Zealand to commit to Earth Hour.
Mayor of Christchurch, Bob Parker, also gave his full public backing to Earth Hour. WWF-New Zealand Executive Director, Chris Howe, and Editor of The Press, Andrew Holden encouraged people and businesses in Christchurch to commit to Earth Hour, by switching off their lights on 29 March at 8pm for one hour.
