David Suzuki had the following to say about permaculture:

“Permaculture is the most important activity that any group is doing on the planet.”

The Permaculture Society defines permaculture as:

“A whole systems design philosophy, integrating a balanced diversity of coordinated understandings of natural law, of scientific practices, and of human activities and needs, to be used for the benefit of people, for the Earth, and for the future.”

Bill Mollison, the principle founder of permaculture, defined it as:

“Permaculture is a philosophy of working with, rather than against nature; of protracted and thoughtful observation rather than protracted and thoughtless labor; and of looking at plants and animals in all their functions, rather than treating any area as a single product system.” ~ An Introduction to Permaculture, Mollison, B. (1991)
