Anyone who believes that there is no such thing as global warming must be blind or unintelligent.

It is remarkable how weak international political responses have been. The failure of global summits on the environment make it plain that our politics are subject to technology and finance.

Humanity is called to take note of the need for changes in lifestyle and changes in methods of production and consumption to combat this warming, or at least the human causes that produce and accentuate it.

The Earth is protesting for the wrong that we are doing to her, because of the irresponsible use and abuse of the goods that God has placed on her. We have grown up thinking that we were her owners and dominators, authorised to loot her. The violence that exists in the human heart, wounded by sin, is also manifest in the symptoms of illness that we see in the Earth, the water, the air and in living things.

The Earth, our home, is beginning to look more and more like an immense pile of filth.

When it comes to the care of our common home, we are living at a critical moment of history.
