The encyclical letter Laudato Si is available here on the Vatican website. Pope Francis calls for a revolution, and a recovery:
114. All of this shows the urgent need for us to move forward in a bold cultural revolution. Science and technology are not neutral; from the beginning to the end of a process, various intentions and possibilities are in play and can take on distinct shapes. Nobody is suggesting a return to the Stone Age, but we do need to slow down and look at reality in a different way, to appropriate the positive and sustainable progress which has been made, but also to recover the values and the great goals swept away by our unrestrained delusions of grandeur.
The revolution is a change in human culture, a renewed focus on values that are important to us.
