Script: [Every year, visitors to the most pristine places on earth send over 100 million pounds of garbage to landfills. This is a problem we need to solve.] National Park Advocates: "Landfills are the largest man made things in the world today. The National Parks are such a treasure, anything we can do to help preserve them: that's great. We can’t do it alone. It is crazy how much garbage I produce when I go camping, let alone this many people here. These things are horrible you can’t recycle them. The system is sick.” [Subaru Presents: Who We Are Is What We Leave Behind] National Park Advocates: “There is a deep need for these places that we love to death to be more aware of how we love them. We are just building a mountain, out of garbage.” [A new series documenting our initiative to make the National Parks Zero-Landfill. Watch at Subaru.com/environment].
