The ecology of freedom

The Ecology of Freedom: The Emergence and Dissolution of Hierarchy is a 1982 book by the American libertarian socialist and ecologist Murray Bookchin, in which the author describes his concept of social ecology, the idea that ecological problems are caused by human social problems and can be solved only by reorganizing society along ecological and ethical lines. The book is considered Bookchin's magnum opus, but it has also been criticized as utopian.
