The Earth Hour initiative takes place today.

Communities around the world are switching off their lights for an hour from 8.30pm local time.

The World Wildlife Foundation (WWF) campaign is a moment for everyone worldwide to come together and show their solidarity for building a sustainable planet. This year’s Earth Hour is raising particular awareness of the need to take action to protect the ‘planet’s biodiversity and nature’.

Join the conversation on Facebook and on Twitter using hashtags #EarthHour #Connect2Earth – and switch off for an hour at 8.30pm your time.
