The results suggest that the environmental contribution of the narrative conceives nature as a whole that has the category of subject where life develops; as well as the reflection that what is bad is harmful and must be rejected for the coexistence of a balance, from an ethical-moral perspective and contribution.

They practice the law of retribution to nature by planting native and ex...
