Today is 07-07-07. For some, a lucky day to pick up a lottery ticket. For others, a good day to stage a worldwide concert event on all of the 7 continents to raise awareness about the climate crisis.

On the Live Earth web site, you can stream live footage from all of the world’s concerts, as well as watch some educational shorts and read up on how minor changes over large groups of people can have an enormous effect. The traditional ‘get involved’ section of the site is all about promising to change a few bulbs to CFLs, shopping for energy efficient appliances, and making sure everything is turned off when you leave your apartment or house. Really, all stuff we should be doing anyway.

So if you’ve got some time today, check out one of the webcasts, learn up on some practical ways to green your life, and sign the Live Earth Pledge, which demands our government start taking this issue seriously, and asks us to look for ways to help as individuals, too.

At the very least, try to check out the band from Antarctica – Nunatak. If there’s something I can get behind more than a worldwide concert for climate change, it’s a band playing outside a sub-zero research station composed entirely of scientists.
