Dave Foreman was one of the founders of Earth First, the radical ecology movement in the United States. Generally, Foreman is a "wilderness" EarthFirst!er, and might not be so inclined to agree with some of the social justice positions that many EF!ers take today.

Since 1989, when Foreman was arrested by the FBI, he has been less active. He claims that he was set up. Foreman's lasting contribution to Earth First! is the creation of a guide to monkey wrenching, which is now in its third edition.
