Why expand the National Park System? That can be a controversial question. There are many folks who would love to see additional units added, and there are just as many who say the National Park Service does not have the staff or funding to adequately maintain the existing park system.

We've been exploring that question in recent weeks and months, and an argument can be made that since national parks carry the highest protection of natural resources in the country, we should expand the park system to better protect biodiversity and, if possible, help it grow.

In this week's show, Lynn Riddick helps me present you with a story that explores the question of expanding the National Park System for the sake of biodiversity. If you prefer reading the story, rather than having it narrated to you, the long-form post is on the Traveler.

At the end of our story about expanding the park system, Lynn returns with a short audio postcard from Big Cypress National Preserve.
