Do you think of the wilderness as something far away? Not in the age of climate change and human population growth. The real wilderness is always underfoot—the complex systems underlying life on Earth that we barely understand. It’s our inheritance, our guardianship to understand traditional and indigenous knowledge of Earth as a vast, cultivated landscape. Land managers such as Miguel Santistevan, Lani Malmberg and Peter Warshall celebrate the fact that we are all gardeners. They reveal brilliant innovations and ancient wisdom for how to get good at it.
