The premise: At 8:30 PM local time, wherever you live on planet earth, Saturday 28 March 2009… turn off your lights for an hour. A global rolling voluntary blackout. Started as a local Sydney event in 2007 and suddenly, last year, found 50 million people participating globally.

In a similar vein, I also joined the I Dont care How Comfortable Crocs Are, You Look Like A Dumbass Facebook group, which boasts an impressive 1.5 million members compared to Earth Hour’s measly 200,000. I mean, climate change is bad and all, but the Crocs? Global pandemic of epic proportions.
