A message from the Conservative Leadership Foundation in Australia:

"Originally conceived by the Competitive Enterprise Institute in 2009, Human Achievement Hour coincides with the earth hour campaign but salutes those who keep the lights on and produce the energy that makes human achievement possible.

Millions of people around the world will be showing their support for human achievement by simply going about their daily lives. While earth hour activists will be left in the dark, Human Achievement Hour participants will be going to the cinema, enjoying a hot meal, driving their car or watching television.

There is really no limit to how you can support Human Achievement Hour, just like there is no limit to what mankind can achieve.

Human Achievement Hour 2010 will be between 8.30pm and 9.30pm on Saturday 27 March."
