Battleground Earth: Ludacris vs. Tommy Lee

Battleground Earth follows a tried-and-true format, pitting the two teams against each other in a series of wacky events. The twist here is the show's focus on the environment. The contests all have some connection to the green movement, and the participants frequently talk about the importance of recognizing mankind's negative impact on the planet. The two musicians are frequently joined by celebrity guest stars, who echo this sentiment.

But a lot of the participants' talk about living a green lifestyle seems to be just that: talk. While they spend a lot of time advocating a green lifestyle, the series doesn't really show them making any obvious changes to their own lifestyles. And while the competitions all have a green theme, it's not clear that racing to sell as much fried food as possible so the used oil can be used to produce biodiesel will really do much to save the planet. And when one team climbs into a private plane at the end of an episode, it seems like the group is only paying lip service to their message of change.
