Sounds like good lyrics for Congress to follow when trying to pass legislation. Among the issues is the actual carbon footprint of Sheryl Crow or any wealthy person on the planet exceeds the difference between the output of the Hummer versus the Volt. I am guessing that Sheryl Crow uses commercial airlines, for example, producing more annual carbon emissions than the average citizen of India. World human population exceeds sustainability. The tipping point to environmental degradation down-cycling to mass-extinction has probably already been reached, so smoke another joint, shoot-up on morphine, and prepare to die.
