....why nobody talks about the fact Mars gravity is something along the lines of 0.37ish that of Earth's? Doesn’t such low gravity have disastrous health effects on any living organism from Earth? Moreover, this is something we will not be able to change about Mars.
Or how the soil is contaminated with perchlorates, which is toxic to us. All of it....
Or how the lack of magnetic field will make it impossible to actually keep an atmosphere even if somehow we manage to terraform Mars in the first place.
The cold, IMHO, is the easiest problem to deal with. In fact we have technology to deal with cold weather since the dawn of human civilization. The reason nobody lives in Antarctica is because it makes absolutely 0 financial sense to do so, rather than any kind of technological barriers. It's permanently covered by kilometre(s) thick ice sheet, making access to local resources extremely expensive & impractical. In addition, no colony can survive for long with a negative balance sheet (meaning if the costs of keeping a human alive > the wealth he can extract from said colony over the course of a human lifetime, it dies out). Unless the mother nation is willing to keep the colony artificially afloat while it slowly bankrupts itself.
