U.F.'s O'Connell Center was just one of 11 stops on Crow and David's Stop Global Warming College Tour. Crist met the duo to help promote their cause.

"It's important to stay focused on doing the kinds of things that are responsible and are prudent and that give us an opportunity to protect this beauty that we love so much not only as Floridians but as Americans," the Republican Governor said.

According to David, the purpose of the tour is not to force people to do everything, it was about encouraging people to do something.

After David's portion, Crow performed, followed by a question-and-answer session with the audience.

"We've seen massive, massive fires down in Florida. We've seen terrific storms," the singer said. "It's really time that we all wake up to this and become a part of the solution."
