When I saw the band's front man, Sir Gordon Sumner (a.k.a. "Sting"), promise the Live Earth concert crowd last weekend that he would "work to reduce" his carbon footprint, I laughed out loud. Just what would that mean? Limiting his promoters to using just 12 semis? It's a safe bet that The Police's 38-site, six-month tour will generate a bigger "carbon footprint" than I will in my entire lifetime. Ten lifetimes. Even if I disconnected the catalytic converter on my full-sized SUV and ripped off the muffler.
