Is Space Colonization Better For Human life?
Absolutely. Once in space the problems that humans need to solve will be solved much faster due to demand. These include humanity’s necessary things for life, so forget about resources. Once in space, there are no limits to size and construction methods so you could build a thousand-mile-long spaceship that is just for farming. You could farm using hydroponics. There are also nearly infinite resources for our population at the moment throughout the solar system. We could easily build enough spaceships to hold humanity, we just would need huge time lengths. In space, there is also so much space that that factor also doesn’t matter. Here on Earth, we are already overpopulated. Once we have the technology, we could also terraform Mars, Venus and some of Jupiter’s moons for even more space. Basically literally everything about space is better than where we are now.
