re: What is the deal with colonizing Mars?

Go read some books, dumbass. Not a millennial or snowflake here. Regardless of your opinion on global warming or the possibility of nuclear war, extinction events happen periodically. They've happened here before, and they will happen again at some point. Meteors, comets, and gamma ray bursts are a few of the threats out there that could wipe out life on the planet at any time. If the human race wants to avoid extinction, we have to diversify. Not to mention, Mars is only the first step. Man will eventually have to go interstellar, because the Earth will not survive the sun's red giant phase. Read more, post less, and you won't look like such a dumbass.
