"We all hear and read a great deal these days about our polluted physical environment—acid rain, smog, toxic wastes. But these parents recognize that there is another kind of pollution that is much more dangerous—the moral and spiritual.
"In a recent conference, Elder Boyd K. Packer said, ’As we test the moral environment, we find the pollution index is spiraling upward’ (Ensign, May 1992, p. 66). The Apostle Paul foresaw ‘that in the last days perilous times shall come’ (2 Tim 3:1). And speaking of the last days, the prophet Moroni declared, ’Yea, it shall come in a day when there shall be great pollutions upon the face of the earth’ (Morm. 8:31).
"Sadly, the effects of this great pollution are perhaps most evident in the mass media, films, television, and popular music. Of this, Senator Robert D. Byrd said, ’If we in this nation continue to sow the images of murder, violence, drug abuse, … perversion, [and] pornography … before the eyes of millions of children, year after year and day after day, we should not be surprised if the foundations of our society rot away as if from leprosy’ (Michael Medved, Hollywood vs. America, New York: Harper Perennial, 1992, p. 194).
“Although there are some uplifting exceptions, in most areas of the mass media there seems to be a declaration of war against almost everything the majority treasures most.” (Conference Report, Nov. 1993 Ensign, “Rearing Children in a Polluted Environment”)
Brigham Young
“The soil, the air, the water are all pure and healthy. Do not suffer them to become polluted with wickedness. Strive to preserve the elements from being contaminated by…those who pervert the intelligence God has bestowed upon the human family…Keep your valley pure, keep your towns as pure as you possibly can, keep your hearts pure.” (Journal of Discourses, 8:79-80 as taken from Latter-day Commentary on the Book of Mormon compiled by K. Douglas Bassett, p. 480)
Spencer W. Kimball
“When I…fly over the vast and beautiful expanses of our globe…I have the feeling that the good earth can hardly bear our presence upon it…The Brethren constantly cry out against that which is intolerable in the sight of the Lord: against pollution of mind, body, and our surroundings.” (Ensign, June 1976, p. 4as taken from Latter-day Commentary on the Book of Mormon compiled by K. Douglas Bassett, p. 482)
