What if the cities of the future weren't built in space, but beneath the ocean's surface? Engineers are seriously considering the construction of underwater habitats capable of supporting large populations using advanced life support systems, producing food at sea, and utilizing integrated or renewable nuclear energy. These submerged cities could exist at great depths, protected from storms and climate fluctuations, while ushering in a new era for human life.

Some concepts envision transparent domes anchored to the seabed, generating oxygen from seawater, growing food through hydroponics, and continuously recycling water. Proponents believe these underwater cities could alleviate terrestrial overcrowding, provide stable living environments, and transform marine scientific research by placing scientists directly within the oceanic world they study.
