Five favorite moments from Live Earth, the seven-continent, 24-hour aging-rocker orgy to raise awareness on global warming:

1. Madonna yelling, 'If you want to save the planet, I want you to start jumping up and down. Come on, mother-[bleepers]! Let me see you jump!" (Madonna owns nine homes and has a "carbon footprint" nearly 100 times larger than the norm.)
2. The demonstration on how to wrap gifts in old potato-chip bags
3. The hundreds of iPhone advertisements
4. Supermodel Petra Nemcova blaming earthquakes on global warming
5. The many public service announcements that buying digital music is more environment friendly than CDs. (Al Gore is on the Board at Apple, the largest digital music retailer…)
The most conservative assessment of the flights taken by the superstars is 222,623.63 miles between them - nearly nine times the circumference of the world. The true environmental cost, as they transported their technicians, dancers and support staff, is likely to be far higher.

The total carbon footprint of the event, taking into account the artists’ and spectators’ travel to the concert, and the energy consumption on the day, is likely to be at least 31,500 tons of carbon emissions, according to John Buckley of Carbonfootprint.com. Throw in the television audience and it comes to a staggering 74,500 tons. The concert will also generate some 1,025 tons of waste at the concert stadiums - much of which will go directly into landfill sites.
Next time, let’s have a multi-continent, 24-hour event, featuring large empty stadiums, no performers, no spectators, no SUVs or big limos, and fly nobody anywhere. No carbon footprint, no new crap for landfills.
