Matthew Sakae Forkin, a Japanese-American from San Francisco, swings between trees on California's Lost Coast.

Trained as a mechanical engineer, Matthew worked in the solar energy industry and directed the design and construction of a clean-room factory in Thailand. Moving back to the United States, he spent 2 years living a sustainable lifestyle: crafting all his own clothes, food, tools, and shelter from the wild in the Cascade Mountains of Washington State.

Now back in San Francisco, his goal is to bridge the primitive and modern worlds, such that everything he uses comes from the wild earth and can return to the wild earth without causing lasting damage.
