The work presented has the following approach: starting from the Pope's reflection on the planet and ecological problems, it is intended to show the philosophical influences that underlie Francisco's exposition. These influences make it possible to describe a philosophical profile present in the encyclical Laudato si’. In addition, since philosophy claims to know, it is not exhausted only in knowledge, but tries to know in order to act; therefore, the presence of an ethical proposal follows; and since all ethics leads (...) to action, it follows that action cannot be without some indicators, without an axiology on which human action on the planet revolves. The result is that Francisco offers an ethic of otherness that feels the other as an authentic neighbor, even those who are in the future. It is an ethic of common benefit and caring for the other whose fundamental axis is the person and for this reason he reflects the phenomenon of human life within life on Earth, with which its philosophical approach seems personalist, from a point of Christian view.
