几百年后，地球可能已不适合居住。撤离我们的陆地定居点，我们的物种迁移到海洋中，在水下开始了新的篇章。人类能否在海底建造社区和城市景观？我们的物种会用生物穹顶和巨大的气泡在海洋中定居吗？如果我们的星球表面不再能够维持我们的生存，人类还会生活在水下吗？
Hundreds of years in the future, the surface of the Earth has become unlivable.
Vacating our terrestrial settlements, our species migrates into the ocean and begins a new chapter underwater.
Could humans build neighborhoods and cityscapes on the ocean floor?
Could our species colonize the ocean with bio-domes and giant air bubbles?
If the surface of our planet can no longer sustain us, will humans ever live underwater?
The surface area of Earth is approximately 197 million square miles; however, 71% of our planet is covered in water.
Around 80% of that water has never been explored.
Logistically, studying the ocean is similar to studying a foreign planet.
We can't breathe underwater, just like we can't breathe in an extraterrestrial atmosphere, so we rely on specialized equipment to investigate sub-aquatic habitats.
Investigating the ocean is a constant challenge; but for a moment, let's think outside of scientific research.
