Rachel Carson:
I am not afraid of being thought a sentimentalist when I say that I believe natural beauty has a necessary place in the spiritual development of an individual or a society. I believe that whenever we destroy beauty, or whenever we substitute something manmade and artificial for a natural feature of the earth, we have retarded some part of our spiritual growth.

It is my understanding that Vincent van Gogh took these words to heart:
Sorrowful, yet rejoicing.
