 The latest big reveal of One Piece was revealed long before fans thought.

The ongoing Egghead Island storyline in One Piece has revealed more and more shocking information about the entire world. The most important is that , the world in One Piece would sink due to the rising ocean levels. The scientist Dr. Vegapunk reveals this to the Marines. He was working for them, but now they are hunting him. Eiichiro Oda has been hinting at this plot for quite some time.

It was mentioned most recently after the Lulusia Kingdom's destruction, when the ocean level rose by one meter. Oda has made many mentions of the rising tides in the ocean, dating back as far as Dr. Vegapunk. He may have even been thinking about it back in the Alabasta episode.

Water 7's Aqua Laguna Rising Was One Sign

Water 7 Arc is set in the island of Water 7 which was clearly inspired by Venice's rivers. Water 7 has an annual Aqua Laguna storm, which is a huge storm that makes its way through the island. The storm surges through the island, flooding the lower areas of the city. It has become increasingly more severe with each passing year.

The city's leader, Iceberg, decided that the only way to solve the problem was to make the entire city float. Iceberg may be able to get ahead with the announcement by Dr. Vegapunk. Every year, the water levels in the oceans are rising. The revelation reframes Aqua Laguna's problem as one that the entire world is likely to face in the near future. Oda's finalization of the sinking-world reveal is likely to have begun here, as Vegapunk was first mentioned towards the end the Water 7 saga.

A major clue was dropped during the Alabasta Saga

Water 7 had other implications, but even before that. The Sandora River in the Alabasta Arc is a river which cuts through a desert nation, and it gets more swamped by the sea each year. In Chapter 161, Princess Vivi elaborates further on this issue. The river is less useful as seawater cannot be used to drink or feed crops. This detail is more crucial now that the rising sea level has been confirmed. Alabasta's Sandora River problem will soon affect other countries, just as Aqua Laguna did.

Eiichiro had planned this plot so far in advance? It's possible. Oda may have had an idea of the direction that the story would go all along. This clue is also noteworthy because Vivi, who was a descendant from Nefertari Lili (one of the founding members of the World Government) and didn't remain in Mary Geoise, dropped it in Alabasta. Imu referred to Nefertari's family as traitors, which makes it clear that Alabasta has an important role.

Oda's ability to connect details is impressive, whether he planned it all along or if he was simply doing so. The One Piece has been running for many decades and still weaves a cohesive plot , with foreshadowing that is masterful even today. The series is still very relevant today, even though some chapters took place years ago.
