We cannot know the whole truth, which belongs to God alone, but our task nevertheless is to seek to know what is true. And if we offend gravely enough against what we know to be true, as by failing badly enough to deal affectionately and responsibly with our land and our neighbors, truth will retaliate with ugliness, poverty, and disease.
The atmosphere, the earth, the water and the water cycle - those things are good gifts. The ecosystems, the ecosphere, those are good gifts. We have to regard them as gifts because we couldn't make them. We have to regard them as good gifts because we couldn't live without them.
