Yesterday Giulia told us about NBC’s upcoming Green Week, which will feature environmentally-themed programming, and to help viewers get involved the network has launched a new series of “The More You Know” clips with NBC stars sharing eco-friendly tips.  The campaign is a great way to remind people that just by taking simple, everyday steps, we can greatly reduce our impact on the planet.

The videos feature Amy Poehler, Christopher Meloni, Zachary Levi, Brian Williams and many other stars, giving advice on everything from water and energy conservation to recycling your cell phone.  Check out all the PSA’s here, including the vintage ones and watch the behind-the-scenes footage of the green series below.
