The July 15 issue of the National Catholic Register provides more proof of that, as if any were needed, in a must-read front-page article (click on this post's title), "Contracepting the Environment -- Environmentalists Mum on Poisoned Streams."
The "Greens" who pretend to be so concerned about Earth refuse to say or do anything about all the hormones from artificial contraceptive pills that get flushed into our streams, rivers, lakes and oceans, where they are causing radical deformities in fish, frogs, etc., and wreaking who knows how much more damage to the environment and probably the rest of us.
The now-retired pro-life worldwide missionary Father Paul Marx, O.S.B., Ph.D., has always said, "God always forgives, man sometimes forgives, nature never forgives." Nature itself gives the lie to the smarter-than-thou dissident, anti-life Catholics who defy the Magisterium.
We shoud all read, or re-read, that wise and holy tribute to married life, Humanae Vitae, which Pope Paul VI issued 39 years ago this month, on July 25, 1968. You can find it at www.vatican.va or http://www.papalencyclicals.net/Paul06/p6humana.htm
