The several climatic events in the Book of Jonah present all environmental concerns: the sea calming down (1:15), making a plant grow (4:6), and the sending of a worm (4:7), and all play a particular role in God’s plan. They are used in the text as divine emissaries, human begin is the only one to oppose God’s will in these dramatic scenes. The ecological problem and the attributes associated with the creatures remain a fundamental issue from Jonah to our current daily reality. The worm, a lowly creature, is elevated as well as the ephemeral plant. Accordingly, Jonah has to learn that the plant is appointed by God. The ecological reading on the Book of Jonah invites us to the Pilgrimage of Justice and Peace in relation to the ecological justice.
