Ehrenfeld (2008) concurs with McDonough and Braungart, in his plea for a holistic approach towards sustainability: “Our society is addicted to reductionist ways of solving virtually all our problems. ... Over time, as we engage more and more in this practice, society’s (as well as individual’s) competence to address the complicated, messy problems we confront has diminished. Unsustainability is just such a messy problem. Reductionism will not make it go away.” (Ehrenfeld, 2008, p. 11-12)
