Earth Hour puts spotlight on green issues

Seven thousand cities across more than 150 countries are shutting off their lights for the Earth Hour movement.

    Millions of people in more than 150 countries took part in this year's Earth Hour campaign to raise awareness of climate change. 

    Seven thousand cities took turns to switch off their lights at 8:30pm local time on Saturday.

    The event's organisers say it is not just about powering down for 60 minutes each year. It is also a way to keep the conversation about climate change and the environment going.

    Al Jazeera's Gerald Tan reports.
