Sorry, Brad Pitt, you're not the only hot actor that cares about the environment.
Julia Roberts is now on an environmental mission akin to the one her Oscar-winning character, Erin Brockovich, embarked on.
The 38-year-old actress has agreed to become a spokesperson for Earth Biofuels, a company that develops renewable energies such as biodiesel and ethanol.
"It's very important that we expand our use of clean energy and make a long-term commitment to it," Roberts said. "Biodiesel and ethanol are better for the environment and for the air we breathe."
Anyone willing to disagree with this pretty woman?
Also on the board of directors for Earth Biofules are Morgan Freeman and country music star, Willie Nelson. In one of her first jobs for the company, Roberts will join the push to get the 500,000 diesel-burning school buses in America to switch to clean-burning biodiesel.
"The use of biodiesel is a positive step toward minimizing pollutive emissions and greenhouse gases," Roberts said. "By focusing on school buses, we can affect the health and well-being of the people most susceptible to that pollution â€" our children â€" today."
While Julia has been quiet on the movie scene recently, she has a valid excuse: She gave birth to twins Hazel and Phinnaeus in November, 2004. It's apparent, however, she hasn't lost touch with the memories of potraying Brockovich, the single mother who uncovered illegal dumping of toxic waste by the Pacific Gas & Electric company.
