Battleground Earth: Ludacris vs. Tommy Lee

The whole show is designed to tout the concept of living an eco-conscious lifestyle. The two stars often talk about the importance of living green, as do the many celebrities who make guest appearances. There's plenty of trash-talking and some underhanded dealings as the teams try to jockey for position. It sometimes seems like the show's green messages are secondary to the contest, and while some participants claim to live a eco-friendly lifestyle, others openly admit that they pay little heed to their impact on the environment (though being involved with the program certainly has made them think about it, which perhaps is the goal).

No sex or nudity, but there's a fair amount of flirting between Tommy Lee and one of his team members, Nina.

This show trades on Lee and Ludacris' star power and frequently promotes their musical careers. Plenty of other celebrities make guest appearances, and the participants often visit significant attractions and events, like the New Orleans Jazz & Heritage Festival, as well as local establishments, which appear on screen and are usually referred to by name. The competitions involve a variety of green projects, many of which require products -- and even advice -- from companies that offer such services and are promoted by name.
