"Our environment has been tragically exploited and abused. Although not yet irretrievably befouled, it has deteriorated in too many ways, and a great deal of hard work and effort is required to protect it and repair the damage done by neglect, indifference, and misplaced priorities. However, I am optimistic that man will in fact draw back from the edge of the pit, that he will recognize his vulnerability, and that he will work to reorganize his priorities and motivations."
