The review article comprehensively presents the state of the environment for three of its components: water, air and soil, in relation to existing legislation, plans for environmental changes in Europe until 2030, but also scientific challenges in the European Research Area. It relates the information on the state of the environment and the plan for global society, scientists and managers to Pope Francis' encyclical Laudato si', dedicated to "Care for the Common Home". Each of the environmental elements was discussed in three contexts: legal acts regulating and defining the level of pollution, pollution in Europe and Poland, and a reference to Pope Francis' encyclical and challenges for the future.

The article offers a commentary on the first three parts of the second chapter of the encyclical Laudato si', entitled The Gospel of Creation. Pope Francis wishes to offer his readers great wealth of life experience that emerges from the Bible in order to put it at the service of an "integral ecology" in a fruitful dialogue between science and faith. Due to the great complexity of the ecological issue, a multicultural and multidisciplinary dialogue is required. Beginning with the beauty and goodness of the original creation, the encyclical speaks of a rupture that arose from a primal disobedience that had ramifications for the rest of history. The excursus, which aims to deepen the issue of dominium terrae in an exegetical manner, analyzes four verbs which in two descriptions of creation speak of human influence on nature: dominate and subordinate, nurture and preserve. As humanity, we are invited by the Pope to recognize the value of creation as a gift and to listen to the wounded voice of all creation, rediscovering the courage to heal its many wounds. In this way the contemporary humanity will be able to sing hymns of praise and admiration for God over the beauty of creation. The Pope, summing up biblical and theological teaching, reaffirms the ultimate goal of creation: “all creatures are moving forward with us and through us towards a common point of arrival, which is God” (LS 83). The ultimate plan, implemented in the fullness of God, has already been attained by the risen Christ (LS 83).

Christians profess faith in God the Creator, who in his love placed man at the center of Creation so that he would take care of it. They profess also faith in Jesus Christ the Redeemer of the universe: "Christ is Lord of the cosmos and of history. In him human history and indeed all creation are «set forth» and transcendently fulfilled” (CCC, nr. 668). At the turn of the twentieth and twenty-first centuries, the ecological question in which God’s plan for creation and, in him, for man seems to have vanished. Tackling it is not just a technical question but requires a right vision and, indeed, an ecological conversion. Pope Francis, with the usual foresight and parresía that characterizes him, confessing his own path of ecological conversion – an expression learned from Saint John Paul II – , and inspired by the Canticle of the Creatures of Saint Francis of Assisi, has published the encyclical Laudato si’.

With this article we want to introduce the reader to the reading of Laudato si’, focusing on the ecological question in its breadth of integral ecology, and launching the invitation to an ecological conversion that brings man back to his original relationship with himself, with other men, with Creation and with God.

In his encyclical Laudato si’ Pope Francis expresses his conviction that in order to face the ecological issue of caring for the Earth, it is necessary to join forces, to act communally. Community action for ecology can be seen in the initiatives of the Catholic Focolare Movement, is taken up by the Movement in both scientific reflection and education. The research objective of the article is to show two areas: the first relates to EcoOne, an international network of scientists and practitioners undertaking systematic, interdisciplinary reflection on
ecology, while the second concerns environmental education and, in particular, the specific didactic means of the so-called “Earth Cube”. On the basis of an analysis of the theoretical assumptions of both initiatives and their applications, it is shown that the dialogue between faith and science that EcoOne conducts is part of the essence of integral ecology.The didactics of the Earth Cube awaken in children a love for what surrounds them, thus it touches all dimensions of human life with its message. The forms of FM involvement described above mark a path leading to the discovery of ever new possibilities for creatively responding to the challenges of the LS encyclical.

Today in the era of climate change, the publication of the Encyclical Laudato si' in 2015 has significantly contributed to increasing public attention to the ecological issue. The health service must also take up the challenge of ecological sustainability in hospitals, in the institutions of curative medicine, but also beyond this, in the areas of prevention. This means, for example, working out in each field of public health how it could contribute to ecological sustainability. This article examines a part of the sixth chapter of the encyclical to identify possible points of connection between health education and environmental education. Beyond the corresponding themes and common competencies to be developed in these two fields, the encyclical can contribute to a deeper understanding of health and environmental education in the light of ecological conversion.

The concept of entrepreneurship was presented as well as the meaning of this idea in Encyclical Laudato si'. The desired features of the entrepreneur was described. Then the importance of the economic activity for employees and the society were taken into considerations. The risks connected with economic activities and indications to avoid them given by Francis in the encyclical were quoted and briefly discussed. Some similarities between Pope Francis approach and European Union ESG  (environmental, social, governance) new legislation were mentioned.

The article contains a summary and discussion of the book by Fr. Professor Zygmunt Zieliński, Returns of the bygone time nested in memory. The presented publication also contains an introduction and a scientific study by dr hab. Rafał Łatka, employee of the Institute of National Remembrance in Warsaw. The book was released last year. It is an extensive work of 872 pages and more than 1,100 explanatory notes. Therefore, it is of interest as a source for historical research.
