Neil Pederson’s introduction to tree rings came from a “sweet and kindly” college instructor, who nevertheless was “one of the most boring professors I’d ever experienced,” Pederson said. “I swore tree rings off then and there.” But they kept coming back to haunt him.

The 26-year-old naturalist had expected to find the same level of diversity of plants and animals as he had left behind in the higher latitudes of Plymouth, England. Instead, on the balmy Galapagos Islands, he found a multitude of strange and diverse creatures thriving together.
Trees, is there anything they can’t do? Doubtful. Let’s see: producing half the world’s oxygen, providing habitat for millions of species, creating the soil and timber resources we depend on. Not bad. But all that’s just scratching the surface. As new research shows, there’s a lot more going on beneath the forest floor than we realized.
Sometimes there are just no words. Sometimes there is just a tree and a setting Sun and a sky that turns from a bright yellow to a deep orange. The Film Artist made this video, Be Sunset Tree, and it’s just majestic. How the Sun crosses the tree, how the tree seemingly cradles the light, and how the sky looks like it’s on fire.
