That's the hope of Grammy-winning rocker Crow and David, who produced "An Inconvenient Truth," the global-warming movie that won the Oscar for best documentary.
"It's great to go out and play music, and I love that, too. And it's also nice to make money. But this is not that," Crow said Sunday in an interview. "This is a whole bunch of people dedicating their time, their lives, working for free, for a mission. And it is the most important mission."
The pair rode a biodiesel bus on a 12-campus tour to raise awareness about global warming by engaging students on the topic. It started earlier this month at Southern Methodist University in Dallas, and was timed to end on Earth Day.
David said "federal inaction is no longer acceptable" and is pressing for Congress to enact a bill to impose mandatory curbs on carbon dioxide and other greenhouse gases within two years. She predicted the 2008 election would revolve around three main issues: jobs, terrorism and temperature."I just feel like if this isn't addressed by this administration, if this administration isn't hearing this message loud and clear, then I feel like there's an irresponsibility," Crow said.
Sheryl Crow to Rove: 'You work for me'
On the eve of Earth Day, Crow and ''Inconvenient Truth'' producer David walked over to the presidential adviser's table at the White House Correspondents' Association dinner over the weekend at the Washington Hilton.
Their differences on global warming quickly bubbled over, the Washington Post reported.
''I am floored by what I just experienced with Karl Rove,'' David said. ''I went over to him and said, I urge you to take a new look at global warming. He went zero to 100 with me. ... I've never had anyone be so rude.''
Rove said: ''She came over to insult me and she succeeded.''
As the debate intensified, Crow tried to calm things down but was drawn into the debate.
''You work for me,'' she told Rove, according to the Post. ''No,'' was his response. ''I work for the American people.''
