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.

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.

We're running the most dangerous experiment in history right now, which is to see how much carbon dioxide the atmosphere... can handle before there is an environmental catastrophe.

The poverty of the people and the devastation of the natural environment painfully strike me.

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

If we approach nature and the environment without this openness to awe and wonder, if we no longer speak the language of fraternity and beauty in our relationship with the world, our attitude will be that of masters, consumers, ruthless exploiters, unable to set limits on their immediate needs. By contrast, if we feel intimately united with all that exists, then sobriety and care will well up spontaneously.
