Planet Green is a new channel from Discovery which is beaming eco-friendly information into 50 million American homes. The channel has some ambitious plans.

Planet Green is the first and only 24-hour eco-lifestyle television network with a robust online presence and community. Launching in June 2008, on-air content will reach 50 million homes with more than 250 hours of original green lifestyle programming. Both online and on-air, Plant Green’s content is entertaining, relevant, and accessible to people of all ages and backgrounds. By representing a broad range of ideas and perspectives, Planet Green is taking an active role in generating conversation and motivating individuals to take action when it comes to improving the environmental status of our planet.

Green programming has been turning up more and more lately, but Planet Green is the first attempt at eco-friendly programming being released 24 hours a day 7 days a week.

Whether viewers enjoy the channel remains to be seen, but it seems like a step in the right direction.
