Colloquium: “LAUDATO SI’, THE CARE FOR OUR COMMON HOME”
The Earth, our Common Home: Challenges and Hope!
“The Key Concept of Integral Ecology and
its Evolution in the Church’s Social Teaching”
Cardinal Peter K.A. Turkson
UNESCO – Paris, 9 November 2016
It is truly a pleasure and a privilege to be at UNESCO’s headquarters to reflect on the Encyclical, Laudato sì, the care for our common home. At your invitation this afternoon, I wish to present the theme of integral ecology, so central to the encyclical, and its evolution in the social teaching of the Church, as a concept which helps us appreciate how the encyclical treats the challenges and hope facing the earth, our common home.
Pope Francis’s Encyclical letter “Laudato si:’ on Care for Our Common Home” was released in June 2015 and no longer requires an introduction or comprehensive presentation. It has been received and analysed in many sectors and disciplines: academia, international organizations and NGOs, scientific and popular organizations, religious institutions of different faiths, media and think tanks, Governments and parliaments, and the business sector at the national and multinational levels.
One leitmotif of the Encyclical is that “everything is interconnected”. This point has made a strong impression on all who read the full document. More than one year after its publication, after the first wave of enthusiasm and analysis, it is very meaningful and important to reflect on this interconnectedness here at UNESCO’s headquarters! The structure of UNESCO, its diverse branches and programs and the variety of its activities clearly reflect this interconnectedness – maybe more than any other single international organization. UNESCO also provides an appropriate base for reflections about technology and our relationships with others and with nature – these concerns are expressed in Chapter 3; and about two of the three pillars – namely culture and education – deemed necessary in Chapter 6 in order to sustain “the long path of renewal” sketched for us by the Holy Father.
Indeed, as Madame Bokova explained in an inspiring article on Laudato si’, “L’UNESCO fut créée (…) dans l’idée que la paix ne peut être durable qu’à la condition de s’ancrer dans l’esprit des hommes et des femmes, par l’éducation, les sciences et la culture. Mais pas n’importe quelle éducation, et pas n’importe quelle culture – car celles-ci, pour inspirer la paix, doivent s’appuyer à leur tour sur la promotion de l’éthique, du respect et de la tolérance, en vue de construire la solidarité intellectuelle et morale des peuples”.
We need not take time here to repeat the alarming situation of our common home: “the cry of the earth and the cry of the poor” (§49), the dominance of misleading paradigms (cf. §53, 106-109, 203), such as the globalization of a technocratic paradigm, and the effects of a misguided anthropocentrism (cf. §115-123). These elements are what make Pope Francis’ see an urgent challenge to protect our common home (§13).They should be taken as givens, they should already be clear in our minds.
Instead, let us look together at the evolution of the one concept that is most characteristic of this encyclical, and which helps us appreciate the challenges and hopes Laudato si’ addresses.
I shall offer my remarks in three parts:
Ecology in the Social Teaching of the Church
Our account of Catholic social teaching begins with the encyclical Rerum novarum of Pope Leo XIII, issued in 1891. While that Encyclical focussed on the conditions and rights of workers, it also contained some seeds of current ideas about our natural environment and the attendant challenges. For example, it stated that those who receive God’s bounty in the form of natural resources or property should exercise their responsibility “as the steward of God’s providence, for the benefit of others”.
Blessed Paul VI
A milestone was the Encyclical Populorum progressio of Pope Paul VI. Issued in 1967, it treated many facets of the development of peoples. Two of its key ideas are that development is the new name for peace, and that we need some effective world authority to cope with the scale of challenge in the environmental and financial realms. And it includes this very positive remark: “By dint of intelligent thought and hard work, man gradually uncovers the hidden laws of nature and learns to make better use of natural resources. As he takes control over his way of life, he is stimulated to undertake new investigations and fresh discoveries, to take prudent risks and launch new ventures, to act responsibly and give of himself unselfishly.”
In his Apostolic Letter Octogesima adveniens (May 1971), Pope Paul VI further addressed the inseparable relationship and interdependence between human life and the natural environment, saying: "Man is suddenly becoming aware that by an ill-considered exploitation of nature he risks destroying it and becoming in his turn the victim of this degradation. Not only is the material environment becoming a permanent menace—pollution and refuse, new illness and absolute destructive capacity—but the human framework is no longer under man's control, thus creating an environment for tomorrow which may well be intolerable" (§21). Paul VI also expressed worries about how the concern to control nature through science could put the human dimension under a parallel, but inappropriate control (§38); about the “new positivism” of “universalized technology” (§29); and about notions of “progress” (§41) that embrace rampant industrialization that could turn persons into “slave(s) of the objects” that they make (§9). The combination of themes in this Apostolic Letter makes it a true precursor of the focus on integral thinking of his successors.
In November of the same year and just before the Stockholm Conference (1972) launched the UN Program on the Environment (UNEP), Paul VI convoked a Synod on Justice in the World, which first gave prominence to the link between justice and ecology. Its line of thought suggested a close link between concern for the poor and a concern for the earth, essentially the cry of the poor and the cry of the earth, and adverted to the culture of waste of the rich.
Saint John Paul II
In his first encyclical, Redemptor hominis, on the human person, John Paul II warned about the threat of pollution to nature. Later, in his social encyclical Sollicitudo rei socialis (1987), on the 20th anniversary of Populorum progressio, he focussed on the nature of authentic human development and its moral character. In this regard, he centred on the need for individuals and communities to have full respect for the nature of the human person, whose origin and goal are found in God. He called attention to the need to respect the constituents of the natural world, which the ancient Greeks referred to as the “cosmos” (an ordered system with beauty).
The first consideration is about connectedness. “One cannot use with impunity the different categories of beings, whether living or inanimate – animals, plants, the natural elements – simply as one wishes, according to one’s own economic needs. On the contrary, one must take into account the nature of each being and of its mutual connection in an ordered system, which is precisely the cosmos.”
The second consideration is that natural resources are limited, and not all are renewable. If we treat them as inexhaustible and use them with absolute dominion, then we seriously endanger their availability in our own time and, above all, for future generations.
Thirdly, certain models of development in industrialized areas cause pollution of the environment, with serious consequences for people’s health.
These considerations form a clear moral message: the demands of morality with respect to nature are a sine qua non for the wellbeing of humanity. According to John Paul II, our fundamental conception and application of morality extends to natural ecology—the use of the elements of nature, the renewability of resources, and the consequences of haphazard industrialization.
In 1991, on the hundredth anniversary of Rerum novarum, John Paul II promulgated his social encyclical Centesimus annus. With regard to the nature of private property and the universal destination of material goods, he drew attention to what he termed the ecological question and its connection with the problem of consumerism. Here he referred to a widespread anthropocentric error: this being our failure to recognize that our capacity to transform, and in a certain sense re-create, the world through human work is always based on God’s prior and original gift of all that exists. Man might imagine that he can make arbitrary use of the earth and subject it without restraint to his will. Rather than carry out his role as a co-operator with God in the work of creation, man sets himself up in place of God. The final outcome is a rebellion on the part of nature which is more tyrannized than properly governed by humans.
To correct these faulty ideas, John Paul II pointed out that all of us human beings, as individuals and in our community, must respect the created world and be conscious of our duties and obligations toward future generations. Certainly, the things that God has created are for our use; however, they must be used in a responsible way, for man is not the master but the steward of creation.
Going beyond the natural environment, the Holy Father also drew attention to the destruction of the human environment. Here he introduced the concept of human ecology. Yes, damage to the natural environment is serious, but destruction of the human environment is more serious. The important “Green” movement is rightly concerned for the balance of nature and worried about the natural habitats of various animal species threatened with extinction. But meanwhile, too little effort is made to safeguard the moral conditions for an authentic human ecology. Not only has God given the earth to humanity, who must use it with respect for the original good purpose for which it was given, but the human being (life) too is God's gift to us—indeed, it is the greatest gift. For this reason we must respect the natural and moral structure with which we have been endowed. The encyclical applies this thought to the serious problems of modern urbanization; it calls for proper urban planning which is concerned with how people are to live, and for attention to a social ecology of work.
Based on this expanded social thought on the ecological question, the Compendium of the Social Doctrine of the Church states that "the relationship of man with the world is a constitutive part of his human identity", and that the cry of the earth and that of the poor are related. In his World Day of Peace Message (1990), John Paul II wrote: "The proper ecological balance will not be found without directly addressing the structural forms of poverty that exist throughout the world."  This message inspired the Canadian Conference of Catholic Bishops to declare that "ecological harmony cannot exist in a world of unjust social structures; nor can the extreme social inequalities of our current world order result in ecological sustainability."
To sum up the contribution of John Paul II on our topic of (environmental) ecology: In Catholic social teaching, respect for the natural environment and the human environment are inseparably and closely linked. On the one hand, man must respect the natural environment by not abusing it. On the other hand, the human environment receives the even greater respect it deserves when we respect the natural and moral structure with which we have been endowed. The more we respect our natural and moral structure, the more we respect others and also the created world. The natural environment and the human environment have a close relationship, and for the natural environment to be respected demands that the human environment be respected above all.
Pope Benedict XVI
In the new millennium, Pope Benedict XVI, in his Message for the World Day of Peace (2007), described four variants of ecology: the ecology of nature, and alongside it, a human ecology which, in turn, demands a social ecology, and, finally, the ecology of peace. For peace to be effected in the world, we must be conscious of the relationship between natural ecology and human ecology. The ecology of peace is comprised of peace with creation and peace among men, which presupposes peace with God.
The example of energy supplies illustrates the close connection between natural ecology and the human ecology and the consequences for peace. Increased industrial production in recent years has led to increased energy needs. The subsequent unprecedented race for available resources has caused, on an overall basis, a rise in energy prices. Benedict XVI expressed serious concern for those affected, namely, for those suffering in the less developed countries who were excluded, as well as the injustices and conflicts that may be provoked by the race for energy resources. He affirmed the urgent need in international relations for a commitment to human ecology that can favour the growth of an ecology of peace; and this, he said, can occur only when the human family is guided by a correct understanding of the human person, that is, an understanding that is not prejudiced by ideology or apathy. 
The following year, during his Apostolic Visit to Australia, Benedict XVI drew attention to the beauty of the natural environment created by God. But this natural environment, he went on to observe, now bears scars as well, including erosion, deforestation and the effects of devastating drought. At the same time, the world’s mineral and ocean resources are being squandered and water levels are rising. He also drew attention to the human environment, the highpoint of God’s creation, and the genius of human achievement such as advances in medical sciences, the wise application of technology, and creativity reflected in the arts. But the human or social environment also has its scars, such as alcohol and drug abuse, the exaltation of violence, sexual degradation and depravity, and the false notion that there are no absolute truths to guide our lives. He affirmed the true nature of human life that entails a search for the truth, the good and the beautiful. To this end, according to Benedict XVI, we make our choices and exercise our freedom, knowing that there we find happiness and joy.
In his landmark social encyclical, Caritas in veritate, Benedict XVI dedicates the entire fourth chapter to the issue of the environment and human existence: “The Development of Peoples, Rights and Duties, The Environment.” Fundamentally, “the way humanity treats the environment influences the way it treats itself, and vice versa.” The relationship between human life, and the natural environment which supports it, is inseparable. It is "that covenant between human beings and the environment, which should mirror the creative love of God, from whom we come and towards whom we are journeying". Furthermore, the Book of Nature is one and indivisible, and it includes not only the environment but also individuals, the familiy and social ethics. Accordingly, our duties towards the environment flow from our duties towards the person. But the "decisive issue", in the relationship between man and his world, in natural and human ecology, "is the moral tenor of society".
What Pope Benedict affirmed here is a mutual relationship between natural ecology and human ecology: that we must respect the created world and that we must respect the way in which the human person has been created, for only in this way will we be able to fulfil our freedom. Such an affirmation, moreover, is not a religious claim but the statement of a natural fact.
So the Holy Father called for an integral understanding of the world and the human person: one that respects both the created world and the highpoint of creation that is the human person.
Pope Francis on Integral Ecology
Elected three years ago, Pope Francis has rooted his own teaching deeply in the teachings of his predecessors on the relationship between natural and human ecology. He has promoted care for creation, integral human development, and concern for the poor and the aged in his homilies, addresses and messages at various audiences and events, and in his Evangelii Gaudium. All this culminated in Laudato si’ released in mid-June 2015. The second half of 2015 was decisive for our topic: in July, the Third International Conference on Financing for Development in Addis Ababa; in September, the U.N. General Assembly on the Sustainable Development Goals running until 2030; and in December, the COP21, the Climate Change Conference in Paris.
Pope Francis himself offers us the core message of Laudato si’ in a short video. Let us watch it now.
The key take-aways from the Laudato si’ video are clear:
The foundations of Laudato si’ are found in the biblical narrative. Genesis teaches us that “human life is grounded in three fundamental and closely intertwined relationships: with God, with our neighbour and with the earth itself” (§66). Regarding the relationship with the earth, Pope Francis turns to His Eminence Bartholomew I for his prophetic teaching: “For human beings … to destroy the biological diversity … by causing changes in its climate,” by contaminating “the earth’s waters, its land, its air, and its life – these are sins” (§8), as are ruptures in our relationship with God and with our neighbour. And when one of these relationships is broken, the others are broken too, and our insertion in the universe is no longer integral—it is fractured, fragmented and partial.
On this biblical basis, the path of Laudato si’ unfolds in great and inter-related detail. The following six points help to convey its essential message:
By bringing these perspectives together with their impact on concrete human experience, Laudato si’ wishes to persuade the world that the moral dimension must be omnipresent. As all the Popes since Paul VI have insisted in various ways, there are no morally neutral decisions about the economy, production, commerce and trade. Such decisions affect both the natural world which is our common home, and all of us inhabitants of that common home.
In Laudato si’, Pope Francis lays out five aspects of the great effort needed in order to reduce our footprint and reverse the deterioration of the natural and social environment, and so to reshape and assure the future of our planet:
Thus, the Encyclical proposes “an approach to ecology which respects our unique place as human beings in this world and our relationship to our surroundings” (§15). The paradigm of integral ecology is an inclusive, dynamic proposal which articulates the fundamental relationships of each person with God, with other human beings, and with creation:
When we speak of the “environment”, what we really mean is a relationship existing between nature and the society which lives in it. Nature cannot be regarded as something separate from ourselves or as a mere setting in which we live. We are part of nature, included in it and thus in constant interaction with it... It is essential to seek comprehensive solutions that consider the interactions within natural systems themselves and with social systems (§139).
Integration is the opposite of fragmentation and isolation: “nature cannot be regarded as something separate from ourselves or as a mere setting in which we live” (§139). Rather than think of our relationship with the natural environment as separate from other spheres of human interest and activity, let us see nature as an integral part of a greater whole which includes the social, political and spiritual, material goods, the economic sphere and so on.
In this Pope Francis resonates loudly the sentiments of his namesake, St. Francis of Assisi, "who shows just how inseparable is the bond between concern for nature, justice for the poor, commitment to society, and interior peace”. He is “the example par excellence of care for the vulnerable and of an integral ecology lived out joyfully and authentically” (§10). Then recalling Francis of Assisi' view about the kinship of the human family with nature, Pope Francis asserts that our integration with the universe is inbuilt: “We ourselves are dust of the earth (cf. Gen 2:7); our very bodies are made up of her elements, we breathe her air and we receive life and refreshment from her waters…We are part of nature, included in it and thus in constant interaction with it” (§2, 139). From conception to the moment of death, the life of every person is integrated with and sustained by the awesome panoply of natural processes. Humanity must reciprocate – we must nourish and sustain the earth that nourishes and sustains us.
Francis of Assisi points to the integration of the human and the natural, and so does the word care in the encyclical’s title. The terminology of stewardship appears only twice, but care comes up dozens of times. This bespeaks an intimate relationship that goes beyond jobs and accountability. Stewards can work within the boundaries of their responsibilities, and not deal with what falls outside those boundaries. This is to operate within a silo. But if I care, I look to the objects of my care – my children, my community, my world – and I see no absolute boundaries to my engagement. I might even die for them!
“Everything is closely interrelated,” says Pope Francis, “and today’s problems call for a vision capable of taking into account every aspect of the global crisis” (§137). Therefore, "we urgently need a humanism capable of bringing together the different fields of knowledge, including economics" and science (climate science etc.) "in the service of a more integral and integrating vision." (§141) When we embrace integral ecology, we avoid silo thinking in favour of interconnection and holism. Only interconnection will let us “find adequate ways of solving the more complex problems of today’s world, particularly those regarding the environment and the poor; these problems cannot be dealt with from a single perspective or from a single set of interests” (§110). No branch of science, no form of wisdom -- including culture, religion and spirituality -- should be neglected (cf §63). “Today, the analysis of environmental problems cannot be separated from the analysis of human, family, work-related and urban contexts, and of how individuals relate to themselves.” (§141).
Building on this core idea, Pope Francis explores integral ecology in several areas of application. It comprehends “our unique place as human beings in this world and our relationship to our surroundings”, in the varied aspects of our life, in economy and politics, in various cultures, in particular those which are most threatened, and in every moment of our daily lives.
In the contemporary world, where “injustices abound and growing numbers of people are deprived of basic human rights and considered expendable”, working for the common good means to make choices in solidarity based on “a preferential option for the poorest” (§158).
The common good also regards future generations: “we can no longer speak of sustainable development apart from intergenerational solidarity” (§159). Here, in the context of integral ecology, Pope Francis invokes care for our children to formulate his pivotal question about the environment: “What kind of world do we want to leave to those who come after us, to children who are now growing up?”(§160).
In conclusion, let me observe: As we confront the threat of an environmental catastrophe on a global scale, I am confident that a shaft of light has already begun to break through the many heavy clouds about ecology, and to bring us what Pope Francis describes as the warmth of hope! Most importantly,
we become together revolutionaries of tenderness and sympathy, overcoming the world’s pervasive indifference and inequities with care for the earth, our common home, and its poor. Thus, if hope generates energy which stimulates the intellect and gives the will all its dynamism, then the Encyclical Letter: Laudato sì, on the care for our common home is itself the hope that initiates a millennium of respect for life, of our care for God’s creation, of our care for the poor in solidarity and justice, and, particularly, of peace.
We received the earth as a garden from the hands of the Creator, let us not pass it on to those who come after us as wilderness, a desert!
Thank you all for your kind attention!
