The linkage between mankind and duty to care for the earth is established (Holy Father Francis, 18).

The fifth chapter makes proposals towards a sustainable ecological relationship and care of the environment (Holy Father Francis, 40).

It proposes the need for mankind to unite and jealously protect his environment as instructed by the Creator. The last chapter advocates for a change in lifestyle for mankind as well as increased spiritualism for all people (Holy Father Francis, 56).
