The encyclical letter Laudato Si is available here on the Vatican website.
58. In some countries, there are positive examples of environmental improvement: rivers, polluted for decades, have been cleaned up; native woodlands have been restored; landscapes have been beautified thanks to environmental renewal projects; beautiful buildings have been erected; advances have been made in the production of non-polluting energy and in the improvement of public transportation. These achievements do not solve global problems, but they do show that men and women are still capable of intervening positively. For all our limitations, gestures of generosity, solidarity and care cannot but well up within us, since we were made for love.
It seems that some of the pessimism of the 60’s isn’t wholly warranted, that in many cases nature rebounds to human amazement. If we human beings were “made for love,” that the planet itself was made for fecundity.
