John Muir was among the early advocates for preserving the Tongass National Forest. Teddy Roosevelt declared it a national forest — America's largest. But why are people from California to Texas to Maine so passionate about a forest in remote southern Alaska? Much of that passion is owed to the fact that some places stir the imagination and therefore, the soul. People also understand intuitively that the campaign to save the Tongass is about something larger than even that vast forest: It’s about what we value as a society.
