So, did/will you switch off for Earth Hour ? ABC News reported that "Landmarks across Australia were being plunged into darkness, also including Parliament House in Canberra and Melbourne's Luna Park and Federation Square".

Earth Hour started in 2007 in Sydney, Australia when 2.2 million homes and businesses turned their lights off for one hour to make their stand against climate change. Only a year later and Earth Hour had become a global sustainability movement with more than 50 million people across 35 countries participating.

After all, every little bit helps ... right ?
