Many argue that the world is in a state of crisis and that the human race is the cause. As a species, we are approaching an important turning point in our history, and if we make the wrong decisions we might be facing a future of deprivation, over population, hunger, and instability. Ultimately, many believe that we will eventually be forced to colonize space. Last year, the 100 Starship Symposium set on course a project to design and build an economical and practical spacecraft for interstellar travel.
But with the very immediate worries about over population, it might not be a good idea to wait for interstellar travel and the colonization of other worlds. Fortunately, there are also many suggestions in place for large space structures designed as places for people to live in their millions, much like a city is on Earth. Of course, building a space habitat comes with thousands of challenges, including: construction in space, recreating a livable atmosphere, recycling waste, producing artificial gravity, transporting food and materials to the habitat, and convincing people such a venture is worth it.
