“If future generations are to remember us with gratitude rather than contempt, we must leave them … a glimpse of the world as it was in the beginning, not just after we got through with it…once man can no longer walk with beauty or wonder at nature, his spirit will wither and his sustenance be wasted.”
– Lyndon B. Johnson, President of the United States
