Would it be possible to build a massive seawall, say maybe even made from metal that could rise as the sea level rises to prevent being erased?
I am not considering costs here, nor beauty, only if such a wall would be able to resist the force of the entire ocean trying to get into the "empty" pool.
- Is it feasible?
- What kind of material would be required? How high could one go?
- In the event of a leak, "terrorist" assault, what kind of disasters and how quickly would the Island become "erased"
You can give an example approximation on the size of the Island.
