#space colonization
There is something so unbelievably selfish and fucked up about people thinking we can destroy our planet, OUR HOME and the home of everything else that lives here, and then just fuck off to another planet to repeat the cycle.
Even just ignoring the fact that it’s NOT POSSIBLE and will NEVER be possible unless we can magically create some bullshit scifi terraforming technology that lets us fundamentally alter entire planets not just on the surfaces but also at their cores and atmospheres, it’s also such an irresponsible and frankly colonialist mindset. We can’t just use up the “useful” things from a planet and then toss it in the garbage like it doesn’t matter.
I said this on twitter but you genuinely do not need any understanding of engineering or space technology to know that we will never terraform mars. Most biologists can tell you why but even a layman who understands anything about nature can tell you there is no amount of money or technology that will ever recreate a sustainable ecosystem on a giant ball of toxic irradiated sand. For most of the time that life existed on EARTH you would have immediately died from the difference in atmospheric composition.
The only reason we even have an oxygen-based atmosphere is that one day one single bacterium evolved into the first photosynthesizing cyanobacterium and its spread caused the extinction of an entire methane-based global ecosystem.
It took a billion years of evolutionary and geological events to create the world we live in and at absolutely any single second it all could have suddenly veered off down a different path. 1% of the money and effort it would take to inhabit mars could make our own entire planet a better place first.
^ mars can’t retain an atmosphere no matter how hard we try
also - why are we trying to do colonialism again?
^ we would have to start the inner core of mars spinning to generate an electromagnetic field in order to maintain a sufficient atmosphere
