Safeopedia explains Monkey Wrenching
The term monkey wrenching came into use after Edward Abbey published his novel entitled The Monkey Wrench Gang in 1975, which followed the activity of a group of environmental activists in Arizona and Utah. This term was used occasionally in the 21st century to describe other kinds of activism and became a common term. An equivalent term to describe monkey wrenching is ecotage.
