Ok then, lets figure out what we need for terraformation! What do you think about 2? Would you miss a red, barren, craterish planet in the Solar System if we turned Mars into green plains with seas, forests, coulds and cities? There are two reasons I see for not colonizing planets, which we could colonize with our technology:ġ: Because it wouldn't be worth it economically.Ģ: Because the natural state of the planet was worth preserving (or rather, letting continue without our intervention). I think, by the time we could terraform Ventus (what a typo, VENUS!), we would have found plenty of other Earth-like planets (in day-length, gravity, composition at least, not neccesarily life) which we could actually travel to. Compared to asteroids etc., I think we are by far the biggest threat to ourselves (thinking of how rare events big asteroid/comet impacts are).Īnd we can let all the human-made climate change denialists have a huge racing track for the most polluting cars EVER on Mars. I definitely think we should colonize other planets, when we are capable of it, assuming we and our even bigger greed don't destroy ourselves or the entire Earth first. I agree with the point by Mudkipz and Karakris that there are a lot of threats which could exterminate us if we have only one planet, but which we could survive if we spread out on more (depending on how developed the colonies would be, but ideally self-sustaining). Perhaps we whould start with Mars - and then later, if Technologies in the future permit, Terraforming Venus. The further we spread Humanity - with sufficient sixed viable populations - then the better our chance of long-term Survival would be. If we are including Planets not in our Solar System - then massive Solar Storms, Nova or Supernova Events. Massive Meteorite Collisions ( ELE ), Major Geological / Vulcanic Events. These are VERY UNLIKELY to happen on more than one Planet at the same time.
Economic Collapse, Ecological Disasters ( of our own making ). Political Mistakes ( assuming the Planets run their own affairs, at least semi-independently ), Political Turmoil, Politically Motivated major Terrorist actions ( some of the ideologies of Territorist may be irrelevent on other Planets ). I except I will get TOTALLY SLAGGED for Expressing My Opinions.īut - here we go - obviously, the more PLanets we can colonise, the more we are actually gonna be "buiffered" from a lot of different kinds of threats. Liquid Nitrogen will be shipped in from Moons of Outer Planets. Ice Asteroids being impacted to impart spin and create Hydrosphere.Ĭyanobacteria and Phytoplankton will convert CO2 to Oxygen - along with Nano-Bot Processing Units. New Diana Moon being built from Debris and Asteroid waste. In orbit between Asteroids and Jupiter - more being removed. Population - 400 Million, and growing - Cities Built and growing.ģ0% of excess CO2 shipped away, to form the dry ice Dwarf Planet Aphrodite, We are no sending more to Venus, as part of the Terraforming Project for Venus.Ītmosphere all done, Oceans 95% done - Land and Ocean Eco-Systems developing. However - we did put steering Steam Propulsion Units ( using Fusion Reactors )Īnd Nuclear Reaction Units on several of the outer Ice Asteroids - and sent them to Mars.
Similar things for lots of other Asteroids. That is - Some 6 Million People, Factories, Thermadomes ( Agriculture ), Defensive Bases, I do not think the Colony on Ceres would have been AT ALL Pleased by that.
