Earth Hour

(By the time you read this in, say, Australia, it might be too late. I should have posted yesterday, but I didn't think of it till this morning.)

At 8:30 this evening, local time, switch off all your (electric) lights for an hour, to save the planet! Yes, I know it won't do that, but it's symbolic, innit. Also, easy. (Actually, it's supposed to "Show you care about climate change".)

You can sign up, and see what it looked like last year in places where you would actually notice, on WWF's website. They've been doing it annually for a while, and "over 125 countries, 3,483 cities, 1,277 iconic landmarks and millions of people are taking part".

You're supposed to gather with like-minded folks and do stuff by candlelight, or go out to see your local landmarks switch off, but I'll be on my own, probably watching TV.
