To this end, it expresses the wish that by recognizing ‘the signs of [an economic growth] that has not always been able to protect the delicate balances of nature’ (Homily of Pope Benedict XVI at Loreto, 2 September 2007), all actors will intensify the aforesaid cooperation and strengthen ‘the alliance between man and the environment, which must mirror the creative love of God, from whom we come and to whom we are bound’(Benedict XVI, After the Angelus, 16 September 2007).”
