Demeter had struck the famine on the Earth

Demeter wanted to hide from everyone after becoming enraged at Hades and Poseidon for harming her daughter and herself. She then put on black clothing and went into an off-limits cave. Due to Demeter's intense fury, there were numerous famines on Earth. Food production ceased as a result of the crops starting to perish. As a result of the lack of food, both humans and animals started to perish.

When everyone including the gods knew that Demeter wasn't around, they all made valiant attempts to find her but in vain. Demeter was hiding there, nevertheless, when Pan (the God of the Wilderness) wandered around the cave. He told Zeus about the discovery right away.

Zeus asked Hades to bring Persephone back to Earth so she may see her mother. He asked Hades to give Persephone back to Demeter, and Hades agreed. Hades offered Persephone a pomegranate to eat as she prepared to leave. She consumed pomegranate, which forced her to spend one-third of the year with Hade. Demeter returned to Mount Olympus after giving birth to her daughter at Zeus' request, and she did so by removing the effects of starvation from the planet. Fruits and crops so began to grow and blossom once more.
