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

We must not place the burden on the next generations to take on the problems caused by the previous ones. Instead, we should give them the opportunity to remember our generation as the one that renewed and acted on - with honest, responsible and courageous awareness - the fundamental need to collaborate in order to preserve and cultivate our common home. May we offer the next generation concrete reasons to hope and work for a good and dignified future!

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.

Time, my brothers and sisters, seems to be running out; we are not yet tearing one another apart, but we are tearing apart our common home. Today, the scientific community realizes what the poor have long told us: harm, perhaps irreversible harm, is being done to the ecosystem. The earth, entire peoples and individual persons are being brutally punished.

We have to get to the point where we all come together, and we realize that we're all on the same Earth, and there's one way we can fix it.

We need to grow food, and we need to grow fuel. Imagine if, instead of dust rising into the sky, the carbon started returning to the Earth.
