This coming Saturday 24 March is Earth Hour. Earth Hour is a global movement aimed at raising awareness of environmental issues and ways to take action. All across the globe at 8.30pm, families and businesses are encouraged to switch off their lights for 60 minutes. The DC Primary Environmental Ambassadors would like to encourage as many DC families to join in, by switching off lights at home tomorrow for 60 minutes. In school next week primary classes will all be having an electricity-free block to raise awareness about global energy consumption.
