Someone who has a question doesn't have to use a telephone to query a specialist at the university. They can log onto the Web and readily find an answer to their question. Exploration of web-based education is being pursued by many universities. We must use practices that are ecologically sound. They cannot be one-dimensional, with a single objective.
Sustainable practices have to be economically viable.
Private landowners generally cannot engage in practices that are not economically viable. Sustainability has to be socially stable within the bounds set by society. I consider sustainability to be on a continuum somewhere between the traditional concept of sustained yield, on one end of the continuum, to valuing forests for the sake of non-human needs, on the other end. Everybody is for sustainability, even the logger who harvests the timber resource. They are for sustainability of the resource.
