If Earth Became All Water

from What If: Science, Theory, and Possibilities · host What If

Sea levels are rising at an alarming rate. Water rushes to cover streets, quickly swallowing entire cities. Earth is about to become a real-life waterworld. Can humans survive underwater? Or would this be the end of life as we know it? Sure, our blue planet is already 70% ocean. But that 30% of land is the difference between life and death. If Earth suddenly became completely submerged, humanity's chances of survival would be slim.
