The biblical message and the Church's Magisterium represent the essential reference points for evaluating the problems found in the relationship between man and the environment.969Cf. Paul VI, Apostolic Letter Octogesima Adveniens, 21: AAS 63 (1971), 416-417. The underlying cause of these problems can be seen in man's pretension of exercising unconditional dominion over things, heedless of any moral considerations which, on the contrary, must distinguish all human activity. The tendency towards an “ill-considered” 970Paul VI, Apostolic Letter Octogesimo Adveniens, 21: AAS 63 (1971), 417. exploitation of the resources of creation is the result of a long historical and cultural process. “The modern era has witnessed man's growing capacity for transformative intervention. The aspect of the conquest and exploitation of resources has become predominant and invasive, and today it has even reached the point of threatening the environment's hospitable aspect: the environment as ‘resource' risks threatening the environment as ‘home'. Because of the powerful means of transformation offered by technological civilization, it sometimes seems that the balance between man and the environment has reached a critical point”.971John Paul II, Address to participants in a convention on “The Environment and Health“ (24 March 1997), 2: L'Osservatore Romano, English edition, 9 April 1997, p. 2.
Nature appears as an instrument in the hands of man, a reality that he must constantly manipulate, especially by means of technology. A reductionistic conception quickly spread, starting from the presupposition — which was seen to be erroneous — that an infinite quantity of energy and resources are available, that it is possible to renew them quickly, and that the negative effects of the exploitation of the natural order can be easily absorbed. This reductionistic conception views the natural world in mechanistic terms and sees development in terms of consumerism. Primacy is given to doing and having rather than to being, and this causes serious forms of human alienation.972Cf. John Paul II, Encyclical Letter Sollicitudo Rei Socialis, 28: AAS 80 (1988), 548-550. Such attitudes do not arise from scientific and technological research but from scientism and technocratic ideologies that tend to condition such research. The advances of science and technology do not eliminate the need for transcendence and are not of themselves the cause of the exasperated secularization that leads to nihilism. With the progress of science and technology, questions as to their meaning increase and give rise to an ever greater need to respect the transcendent dimension of the human person and creation itself.
A correct understanding of the environment prevents the utilitarian reduction of nature to a mere object to be manipulated and exploited. At the same time, it must not absolutize nature and place it above the dignity of the human person himself. In this latter case, one can go so far as to divinize nature or the earth, as can readily be seen in certain ecological movements that seek to gain an internationally guaranteed institutional status for their beliefs.973Cf., for example, Pontifical Council for Culture - Pontifical Council for Interreligious Dialogue, Jesus Christ the Bearer of the Water of Life. A Christian Reflection on the “New Age”, Libreria Editrice Vaticana, Vatican City 2003, p. 33. The Magisterium finds the motivation for its opposition to a concept of the environment based on ecocentrism and on biocentrism in the fact that “it is being proposed that the ontological and axiological difference between men and other living beings be eliminated, since the biosphere is considered a biotic unity of undifferentiated value. Thus man's superior responsibility can be eliminated in favour of an egalitarian consideration of the ‘dignity' of all living beings”.974John Paul II, Address to participants in a convention on “The Environment and Health” (24 March 1997), 5: L'Osservatore Romano, English edition, 9 April 1997, p. 2.
A vision of man and things that is sundered from any reference to the transcendent has led to the rejection of the concept of creation and to the attribution of a completely independent existence to man and nature. The bonds that unite the world to God have thus been broken. This rupture has also resulted in separating man from the world and, more radically, has impoverished man's very identity. Human beings find themselves thinking that they are foreign to the environmental context in which they live. The consequences resulting from this are all too clear: “it is the relationship man has with God that determines his relationship with his fellow men and with his environment. This is why Christian culture has always recognized the creatures that surround man as also gifts of God to be nurtured and safeguarded with a sense of gratitude to the Creator. Benedictine and Franciscan spirituality in particular has witnessed to this sort of kinship of man with his creaturely environment, fostering in him an attitude of respect for every reality of the surrounding world”.975John Paul II, Address to participants in a convention on “The Environment and Health” (24 March 1997), 4: L'Osservatore Romano, English edition, 9 April 1997, p. 2. There is a need to place ever greater emphasis on the intimate connection between environmental ecology and “human ecology”.976John Paul II, Encyclical Letter Centesimus Annus, 38: AAS 83 (1991), 841.
The Magisterium underscores human responsibility for the preservation of a sound and healthy environment for all.977Cf. John Paul II, Encyclical Letter Sollicitudo Rei Socialis, 34: AAS 80 (1988), 559-560. “If humanity today succeeds in combining the new scientific capacities with a strong ethical dimension, it will certainly be able to promote the environment as a home and a resource for man and for all men, and will be able to eliminate the causes of pollution and to guarantee adequate conditions of hygiene and health for small groups as well as for vast human settlements. Technology that pollutes can also cleanse, production that amasses can also distribute justly, on condition that the ethic of respect for life and human dignity, for the rights of today's generations and those to come, prevails”.978John Paul II, Address to participants in a convention on “The Environment and Health” (24 March 1997), 5: L'Osservatore Romano, English edition, 9 April 1997, p. 2.
