25. Still, some scientists believe that the only way for humanity to survive is to become an interplanetary species.
Given the challenges humanity is facing just in this present generation, with wars, a global pandemic, droughts, famines, wildfires, and extreme weather patterns caused by global warming, plenty of people are rather pessimistic about the future of humanity. And they aren’t alone.
Scientists predict that the Earth will enter the stage of its life at some point, at which it will begin to expand and hit the Earth drastically. When it becomes a red supergiant, it will swallow the Earth altogether. And before that happens, we could easily get hit by a giant asteroid, like the one that wiped out the dinosaurs. To survive the challenges on this planet and challenges from outer space, many believe that we will have to find a way to live on a planet other than Earth.
