It occurred to me in my junior year of high school. I got my first letter from a big college. I still have that letter to this day - a letter from Indiana.
“If we intend to provide a better life, and a better world, for future generations, we can't ignore the quality of the environment we leave them.”
“Modern technology has become a total phenomenon for civilization, the defining force of a new social order in which efficiency is no longer an option but a necessity imposed on all human activity.”
