This is make sense, I guess, comparing to the idea about finding same planet as earth in space.
The creators of the Water-Scraper believe that the effects of climate change mean it’s “only natural that we will populate the seas someday,” so they designed this sustainable structure for humans to occupy. The Water-Scraper uses wave, wind and solar power, and it even generates its own food through farming, aquaculture and hydroponics. A small forest is nestled on the top of the Water-Scraper, along with wind turbines, a garden and livestock. The living areas are located just below sea level.
