From my column on the enormous dud:

But, hey, I don’t want to bash Live Earth, which is not to be confused with Live Aid (1985, dedicated to eradicating African famine) or Live 8 (2005, promising to relieve African nations’ debts). So with the African continent so well-fed — and debt-free! — who can blame the Celebrity Concern Industry for moving on to its next big success?
The avowed point of Live Earth was to … can you guess? That’s right: raise awareness about global warming. Considering the energy required to put on the show, the nine Live Earth concerts doubtlessly raised more CO2 than awareness. NBC’s three-hour televised version got trounced by “Cops” and “America’s Funniest Home Videos.” Moreover, surely most of the people who attended or tuned in already knew about global warming before they saw the video tutorial about Ed Begley Jr.’s eco-friendly home and sanctimony-powered go-cart.
