Caritas in Veritate - Encyclical - Pope Benedict XVI - Part 31

48. Today the subject of development is also closely related to the duties arising from our relationship to the natural environment. The environment is God's gift to everyone, and in our use of it we have a responsibility towards the poor, towards future generations and towards humanity as a whole. When nature, including the human being, is viewed as the result of mere chance or evolutionary determinism, our sense of responsibility wanes. In nature, the believer recognizes the wonderful result of God's creative activity, which we may use responsibly to satisfy our legitimate needs, material or otherwise, while respecting the intrinsic balance of creation. If this vision is lost, we end up either considering nature an untouchable taboo or, on the contrary, abusing it. Neither attitude is consonant with the Christian vision of nature as the fruit of God's creation.

Nature expresses a design of love and truth. It is prior to us, and it has been given to us by God as the setting for our life. Nature speaks to us of the Creator (cf. Rom 1:20) and his love for humanity. It is destined to be “recapitulated” in Christ at the end of time (cf. Eph 1:9-10; Col 1:19-20). Thus it too is a “vocation”[115]. Nature is at our disposal not as “a heap of scattered refuse”[116], but as a gift of the Creator who has given it an inbuilt order, enabling man to draw from it the principles needed in order “to till it and keep it” (Gen 2:15). But it should also be stressed that it is contrary to authentic development to view nature as something more important than the human person. This position leads to attitudes of neo-paganism or a new pantheism — human salvation cannot come from nature alone, understood in a purely naturalistic sense. This having been said, it is also necessary to reject the opposite position, which aims at total technical dominion over nature, because the natural environment is more than raw material to be manipulated at our pleasure; it is a wondrous work of the Creator containing a “grammar” which sets forth ends and criteria for its wise use, not its reckless exploitation.

Today much harm is done to development precisely as a result of these distorted notions. Reducing nature merely to a collection of contingent data ends up doing violence to the environment and even encouraging activity that fails to respect human nature itself. Our nature, constituted not only by matter but also by spirit, and as such, endowed with transcendent meaning and aspirations, is also normative for culture. Human beings interpret and shape the natural environment through culture, which in turn is given direction by the responsible use of freedom, in accordance with the dictates of the moral law. Consequently, projects for integral human development cannot ignore coming generations, but need to be marked by solidarity and inter-generational justice, while taking into account a variety of contexts: ecological, juridical, economic, political and cultural[117].
