Earth Hour 2012

We are talking about different physical and human geography issues through key stage 3 and 4, and as geographers and human beings we need to pay attention to our environment and look after it. Today's video is going to explain us a global movement that began a few years ago and we could all do as a gesture to show that we really care about the environment, other people and ourselves. Do not forget that the "earth hour" should be something to be done not just one day for an hour. Watch and share!!!
