@bvch7395 What happens when the dome gets punctured by meteorites? Mars thin atmosphere won't stop them. People would have to live in underground tunnels. Oh Joy.

@bvch7395 Power will be another issue. Mars has 50% of the sun's strength compared to Earth so you'll need 2x as many solar panels. They will get badly etched by the abrasive dust meaning people will be tasked to keep them clean and replace them. The only reliable power will be nuclear but at least Mars has the necessary elements. We do have molten salt reactors which are light weight, burn 99% of the fuel (vs 4%) and could work on Mars.

The Mars atmosphere is about 1% of the earth so offers no protection against the cold of space or the dangerous radiation. However the winds are enough to cause all the damage that high winds cause on earth. The only way anyone can live on Mars is underground in tunnels. The surface dust is toxic and extremely abrasive. Basically, you would go there to be a tunneller and to live in those tunnels. The surface is not inhabitable and may never be safe. The dust causing seals to fail is one thing but the atmosphere is too thin to stop meteorites. Sooner or later any sort of biodome will get punctured.

Imagine the pollution and global warming accelerated by all those rocket launches.

Bruce Kent of Greenpeace said, "The planet will survive". He meant that humans could nuke themselves out of existence but evolutionary time would soon restore order and anything we had not erased with bombs would be erased by nature.
