“We are living at the time of man’s final conquest over the wilderness. What we have saved, and what we may save in the next few years, will be all the true wild nature that will remain to pass on from generation to generation in the years ahead. There will never be another chance.” George B. Fell

Founder of the Natural Land Institute
