In his groundbreaking book, “The End of Nature,” Bill McKibben argued that humans needed to fundamentally shift from the way they were relating to nature for the sake of the survival of the planet.

Now, he is weighing the same environmental concerns on a much more personal scale. For three weeks, he hiked west from his home in Vermont’s Lake Champlain Valley to the Adirondacks in New York. He watched and listened for what is natural, what is local, what is still wild, and he came back with a spring in his step.

“Local is the new organic,” McKibben says. As he visited with old friends — a beekeeper, a biodiesel farmer, a vintner — he found concerned individuals striving to live well in their communities and in the world.
