Blue Hole: Little Miami River
What is a village? A small place, yes, as wide as the world, layered with histories and stories, where you can walk wherever you want to go. In my vision of that place, a river like the Little Miami runs through it, and still water like the Blue Hole remains as transcendent as the day in 1851 when Robert Duncanson painted it.
Big Water: Lake SuperiorI’ve canoed on Lake Superior for almost as many years as I’ve been losing eyesight. I return year after year like a migrating loon to learn the other side of a slow, uncertain process that we could call “going blind.” After 35 years with the lake as my teacher, I know what lies on the other side. I call it letting go of sight. Read my essay Big Water.

[Crowther et al 2015] Anstract: The global extent and distribution of forest trees is central to our understanding of the terrestrial biosphere. We provide the first spatially continuous map of forest tree density at a global scale. This map reveals that the global number of trees is approximately 3.04 trillion, an order of magnitude higher than the previous estimate. Of these trees, approximately 1.39 trillion exist in tropical and subtropical forests, with 0.74 trillion in boreal regions and 0.61 trillion in temperate regions. Biome-level trends in tree density demonstrate the importance of climate and topography in controlling local tree densities at finer scales, as well as the overwhelming effect of humans across most of the world. Based on our projected tree densities, we estimate that over 15 billion trees are cut down each year, and the global number of trees has fallen by approximately 46% since the start of human civilization.
