Some Earth Day Links... I think they're all hopeful.
But behold, I will show unto you a God of miracles, even the God of Abraham, and the God of Isaac, and the God of Jacob; and it is that same God who created the heavens and the earth, and all things that in them are.
Yea, all things which come of the earth, in the season thereof, are made for the benefit and the use of man, both to please the eye and to gladden the heart; Yea, for food and for raiment, for taste and for smell, to strengthen the body and to enliven the soul. And it pleaseth God that he hath given all these things unto man; for unto this end were they made to be used, with judgment, not to excess, neither by extortion.
