Fox recently launched a networkwide public service campaign called “Green It. Mean It.” Leading up to Earth Day on April 22, the weeklong eco-themed campaign includes on- and off-air elements including promos starring Fox talent. Here is just one of the “Green It. Mean It” PSA’s:

Omar Epps and Lisa Edelstein from “House,” Emily Deschanel from “Bones” and Kelsey Grammer and Fred Willard from “Back to You” are among those who will offer “green tips” to viewers, and Fox affiliates are offered an “Are You Smart Enough to Save the Planet?” promotion to drive tune-in for a special two-hour “Are You Smarter Than a 5th Grader?”
