There's enough trash floating around the the world's seas to make a metropolis––and that's precisely what one architect is proposing with this underwater city.

The 'Oceanscrapers,' as designer Vincent Callebaut calls them, would suspend in the deep blue, down to 1,000 meters beneath the surface. The unique, organic forms are inspired by the anatomy of jellyfish––creatures that also gave the name of 'Aequorea' to this underwater city.
While the elaborate and fantastical renderings of the fictional submarine structures might look out-of-this-world, it's important to look to these as innovative, green and magical examples of how mankind can improve future infrastructure.
