Excerpts from Pope Francis' encyclical, from climate change to population control

Francis linked global warming to the overarching theme of his papacy — fighting inequality and global poverty. Here are some key passages that will be read closely, on everything from climate change and global warming to abortion and population control.

Climate change has grave implications: "Each year sees the disappearance of thousands of plant and animal species which we will never know, which our children will never see, because they have been lost forever."

Rich countries are destroying poor ones: "The warming caused by huge consumption on the part of some rich countries has repercussions on the poorest areas of the world, especially Africa, where a rise in temperature, together with drought, has proved devastating for farming."

Christians have misinterpreted Scripture: They "must forcefully reject the notion that our being created in God's image and given dominion over the earth justifies absolute domination over other creatures."

Access to safe drinking water is "a basic and universal human right."

Technocratic domination leads to the destruction of nature and the exploitation of people, and "by itself the market cannot guarantee integral human development and social inclusion."

Population control does not address the problems of the poor: "In the face of the so-called culture of death, the family is the heart of the culture of life." And, "Since everything is interrelated, concern for the protection of nature is also incompatible with the justification of abortion."

The international community has not acted enough: "Recent World Summits on the environment have not lived up to expectations because, due to lack of political will, they were unable to reach truly meaningful and effective global agreements on the environment. ... "[T]he Church does not presume to settle scientific questions or to replace politics. But I am concerned to encourage an honest and open debate so that particular interests or ideologies will not prejudice the common good. ... [T]here is urgent need of a true world political authority, as my predecessor Blessed John XXIII indicated some years ago."

Individuals must act: "An integral ecology is also made up of simple daily gestures which break with the logic of violence, exploitation and selfishness. We should also consider taking public transit, carpooling, planting trees, turning off the lights and recycling."

Why are we here on Earth in the first place? "What kind of world do we want to leave to those who come after us, to children who are now growing up?"
