Pope Francis blames human selfishness for global warming in his long-awaited encyclical calling for action on climate change. In the letter, he urges the rich to change their lifestyles to avert the destruction of the ecosystem. In excerpts from the 184-page document:
What kind of world do we want to leave to those who come after us, to children who are now growing up? The question not only concerns the environment in isolation; the issue cannot be approached piecemeal…Today, we have to realize that a true ecological approach always becomes a social approach; it must integrate questions of justice in debates on the environment, so as to hear both the cry of the earth and the cry of the poor.
