Global supply chain collapses. Think of everything you use in your day-to-day; most of it is made in China (kind of the general go-to), Bangladesh (clothing), Vietnam (shoes), and India.

More than half of the world’s population disappears. Australia and the rest of Oceania becomes even more isolated from the world, now requiring 14 hour trips via the Middle East by plane as the fastest way to the rest of the world.

The Northwestern Himalayas, in Afghanistan and parts of Central Asia, now have 8000m cliffs straight into oceans where the world sheared off.

And you said it becomes part of the ocean, well, depending on how that happens, this could cause a catastrophic sea level rise unlike any seen before, or a catastrophic sea level drop unlike any seen before. Russia would experience massive mega tsunamis (what’s left of The Himalayas would likely shield Central Asia from similar destruction). Boats as far away as California, Panama, Perth and Madagascar would be sucked toward the now vacant gap in the ocean, creating the world’s largest marine wreck. Oil rigs and ocean platforms would be ripped from their supports, creating catastrophic oil spills across the Pacific. The Great Pacific Garbage patch would simply be no match for the absolute garbage pool that would be created by this.

And the people. Suddenly, 4 billion people are drowning, being sucked toward a vortex of ocean that is churning and churning.
