EARTH HOUR

Earth Hour is organised annually on the last Saturday of March by the World Wide Fund for Nature (WWF) to reduce climate change. This year over 4,000 cities from 131 countries have turned their lights off during this global event, so that people realise that everyone must take action in order to help our Planet and combat environmental problems.
