Having recently waded into political activism with his girlfriend Angelina Jolie, Brad Pitt is now lending his star power to matters green. That's right, Brad will be narrating "Design: e2, " a six-part documentary slated to air in June on PBS about "the economies of being environmentally conscious." It will explore how everything from building design to recyclable clothing can dramatically lighten civilization's environmental footprint in the 21st century.

"Did you know that over 1.4 billion people do not have access to clean drinking water, that there are over 800,000 million cars on the world's roads today, and that buildings account for 40 percent of world's energy?" says the e2 website. The series will try to explain the implications of these dramatic numbers and add a little optimism to all the doom and gloom.

To be fair, the environment is not an altogether new pet cause for Pitt, who in 2003 joined the Solar Neighbors program and pledged to put solar panels on the Hollywood mansion he once owned with Jennifer Anniston. The program helps raise money to fund solar installations on low-income homes in Los Angeles.
