Feedback Friday: How can music fans "greenify"?

Live Earth London, 2007

It's Earth Hour this Saturday. All over the world, peeps will be turning off their lights and non-essential electric appliances for one hour in an effort to save the world from global warming.

And so today, we're just wondering: How can us crazed music listeners contribute to the betterment of our planet? What is in our music listening habits that aren't exactly helpful to Mummy Earth? Do we leave our computers on all night to download the latest albums? Do we travel solo to gigs rather than carpool? Do we chuck our ciggy butts and empty cans all across the pavements while waiting for our fave acts to finish their soundchecks?

So tell us, chaps: How can music fans "greenify"? Share below!
