The Main Stream Media (heretofore known as MSM) typically doesn't get it. Getting information on Catholic teachings or Church positions from the MSM is perilous at best. So it should be no surprise that this article from Reuters has it wrong.
Is pollution really a sin? While some of us my chaff at the way some liberals have embraced environmentalism (to the extent for perverting the Stations of the Cross into something that is not Christ centered or Catholic) the fact is that pollution is a sin and has always been a sin. As Christians we believe that God has given us stewardship over the Earth. Stewardship means oversight and is related to pastorship. We have jurisdiction over the Earth and it is our duty to protect the lessor species. We are allowed to exploit them for legitimate purposes but poisoning and destruction of the Earth is not the same as the governance of resources that we are allowed as stewards. Remember a steward does not own what he manages, he merely manages for another. The Earth is God's and we are just tasked with its care.
Likewise in the realm of bioethics the sins are no more new than murder has ever been. It was no more right in ancient times to create a human life by conventional means to use for purposes of medical experimentation than it is now to create a life using scientific means for experimentation. To start with all life is created by God, man sometimes acts as God's agent in the act, but God is the creator, and the life, if it is human life contains a soul made in the image and likeness of God and possessing of inherent dignity based on that fact.
Even the more bizzare of the bioethic questions, such as blended human-animal DNA simply leads back to the traditional sins of offenses against the dignity of the soul and the immorality of the treatment of the human as a commodity.
Certainly it is the duty of the Church to continue to remind the faithful of this and clarify the new acts that are old sins, but idea that there could be new sins attempts to undermine the constancy of Church teaching and the Churches role as the Earthly representative of the unchanging God.
