If you missed the Live Earth concerts earlier this month, you didn’t miss much. With seven concerts on all seven continents on 7-7-07 available on dozens of TV stations (and HDTV), both satellite radio networks, terrestrial radio, and streaming live on the web, the world rocked for global warming.

I’m all for covering my footprints, and knowing the city I live in is extremely conscious of recycling makes it all the better.  And while I still think some of Live Earth’s arguments are a stretch, I dropped my jaw when I heard Holly Hunter in a PSA about how buying digital music is more environmentally friendly because there is no oil wasted in making plastic CDs and energy is saved by not physically transporting discs around.

(And since you can find anything on YouTube, here’s the clip)

While this is all true, I doubt the music industry is thrilled by this message. Wasn’t it just a few short years ago when the music industry blamed digital for the drop in CD sales? I hardly think the music industry would support such an argument, since album artwork and “b-side” songs tend to really show off the image and true style of a band.

Should bands just give up on album covers and 10-15 songs an album in the name of the environment?
