The Holy Father dedicated the encyclical letter “Laudato Sì” to the theme in which he writes “our common home is also like a sister, with whom we share life, and like a beautiful mother who welcomes us into her arms”. The Pope writes “Since the middle of the last century, overcoming many difficulties, the tendency has been affirming to conceive the planet as a homeland and humanity as a people living in a common home. An interdependent world does not only mean understanding that the harmful consequences of lifestyles, production and consumption affect everyone, but, above all, ensuring that solutions are proposed from a global perspective and not only in defense of the interests of some countries. Interdependence forces us to think of a single world, a common project. But the same ingenuity used for enormous technological development fails to find effective forms of international management in order to resolve serious environmental and social difficulties. In order to tackle the underlying problems, which cannot be solved by the actions of individual countries, a global consensus is essential that leads, for example, to planning sustainable and diversified agriculture, to developing renewable and low-polluting forms of energy, to to encourage greater energy efficiency, to promote more adequate management of forest and marine resources, to ensure access to drinking water for all ”.
