Why does Demeter go to Olympus?

Demeter goes to Olympus to seek the return of her daughter, Persephone, after she is abducted by Hades to the Underworld. Distraught and angry over her daughter's absence, Demeter's grief causes the earth to become barren, leading to widespread famine. Her visit aims to persuade the gods to intervene and restore balance and fertility to the world by ensuring Persephone's return. Ultimately, her journey highlights the deep bond between mother and daughter and the impact of their separation on nature.
