Pope Francis today issued a sweeping 184-page papal letter, writing that climate change is a global problem with far reaching environmental and social consequences — especially for the poor. He blamed apathy and greed and called on developing countries to limit the use of nonrenewable energy and to assist poorer nations.
"Those who possess more resources and economic or political power seem mostly to be concerned with masking the problems or concealing their symptoms," Francis wrote of the impact of climate change in the encyclical titled "Laudato Si," or "Praise Be."
He called on humanity to collectively acknowledge a "sense of responsibility for our fellow men and women upon which all civil society is founded." And he wrote that climate change "represents one of the principal challenges facing humanity in our day."
Francis said that developing countries, as the biggest producers of harmful greenhouse gasses, owe the poorer nations a debt. "The developed countries ought to help pay this debt by significantly limiting their consumption of nonrenewable energy and by assisting poorer countries to support policies and programs of sustainable development."
In one particularly blunt passage, Francis writes: "The earth, our home, is beginning to look more and more like an immense pile of filth. In many parts of the planet, the elderly lament that once beautiful landscapes are now covered with rubbish. ... Frequently no measures are taken until after people's health has been irreversibly affected."
