Episode 166 - John Perlin is a Professor and Visiting Scholar in the Department of Physics at University of California, Santa Barbara.

John Perlin is a Professor and Visiting Scholar in the Department of Physics at University of California, Santa Barbara. He is the author of A Forest Journey: The Role of Trees in the Fate of Civilization.

 Perlin says, “It is my hope that this edition of A Forest Journey will make clear the imperative humanity faces because losing our forests would not merely be the end of nature, it could mean the end of us.”

Originally published in 1989, the book’s comprehensive coverage of the major role forests have played in human life …….earned its recognition as a Harvard “Classic in Science and World History” and as one of Harvard’s “One Hundred Great Books.”

In this latest edition, Perlin cites data on how humanity has cut down half the trees on the planet in the last 12,000 years and that deforestation continues at an alarming pace with 15 billion trees removed per year. That’s 500,000 square miles of forested land lost since the first edition of A Forest Journey was released.

Perlin is also the author of three other books: A Golden Thread: 2500 Years of Solar Architecture and Technology; From Space to Earth: The Story of Solar Electricity; and Let It Shine: The 6000-Year Story of Solar Energy.

Perlin lives in Santa Barbara, California.
