Places to Intervene in a System
by Donella H. Meadows
Dr. Donella H. Meadows (Ph.D. in biophysics, Harvard University), a Pew Scholar in Conservation and Environment and a MacArthur Fellow, was one of the most influential environmental thinkers of the twentieth century.
The central thesis of Places to Intervene in the System is "Leverage points are not intuitive. Or if they are, we intuitively use them backward, systematically worsening whatever problems we are trying to solve." Leverage points are those "places within a complex system (a corporation, an economy, a living body, a city, an ecosystem) where a small shift in one thing can produce big changes in everything."
