Environmental pollution and climate change represent one og the biggest challenges that humanity is facing today. The increase in greenhouse gas emissions, water and air pollution and the loss of biological diversity have serious consequences for the planet and life on it. In oreder to preserve a sustainable future, it is necessary to urgently take measures to reduce pollution, promote renewable energy sources, preserve ecosystems and adopt sustainable practices in all segments of society. Because of the state of affairs, recent documents of the Churcs's magisterium mention that man is also responsible for his activity over nauture. They warn of the danger of neglecting one's own spiritual and physical strenght while man strives to rule nature. This is why harmony between man and nature is called for. The responsible use of earthly goods and their general purpose is emphasized. Today's man needs awareness of the egological crisis and the need for solidarity for future generations. The main cause of the ecological crisis can be found in the dangers of greed and the lust for power. The human race builds a false nature whit these actions, which leads to the degradion of man and his environment. The encyclical Laudati si', as an illustrative example of the church's relationship to the „shared house“, emphasize the moral dimesnion of the ecological conversion, i.e. a change in the way of thinking and behavior so that man can establish a proper relationship with nature. Ecotheology requires consideration ofa wide range of the environmental topics, including environmental protection, and injustice. Solving the ecological crisis requires dialogue and global cooperation. Caring for the environment implies a deep spiritual conversion of all people. Cristian are called to a relationship with nature calls from their relationship with Jesus Christ. Finally, the effort to preserve nature calls for a change in the way of life and action in order to preserve God's creation for future generations. In this sense, Christian care for the environment advocates a complete ecology that includes God, people and all of creation, because we are all in a shared home.
