Denali National Park & Preserve is the centerpiece of the Alaskan frontier. Each year, millions of visitors make the trek to enjoy its raw majesty. But with all of those visitors comes the challenge of what to do with the abundance of waste they bring with them... and leave behind. We'll explore ways to leave a lighter footprint through composting, recycling, and sustainable alternatives. After all, when the U.S. Parks Service can keep six million acres of wilderness clean, our own backyards should be a snap. We'll also visit a few local residents to see how these innovative gardeners are producing bounty in spite of unlikely conditions. Local Angle: Local businesses are leading the way in setting the example of what companies large and small can do to set the example of reducing landfill waste coming into Denali National Park as well as the surrounding community.
