"It is the time for courageous actions and strategies to implement a culture of care," said the 78-year-old Argentine religious. "I am convinced that we can make a difference and I have no doubt that the United States and this Congress are called to play an important role," said the pontiff.
Francisco recalled that in the encyclical Laudato Si he sought to support the effort to adopt a new stance on the risks posed by climate change.
It is, said the pontiff, to seek "to avoid the greatest consequences that arise from environmental degradation caused by human activity."
In a speech that lasted for just under an hour, Francisco reinforced that a "comprehensive" approach is becoming urgent in order to "combat poverty, restore dignity to the excluded and simultaneously to care for nature."
The Pope's speech is in frank coincidence with the positions defended by the US President, Barack Obama, although the two houses of Congress, where Francis delivered his speech, are frankly divided on the issue.
