There's almost nothing we could do to this planet which would make Mars a more attractive option. I guess there's always a meteor/comet risk, but practically anything else still leaves Earth as a better option.
Even if we all had to live in bio-domes because the planet was so polluted, it would _still_ be a better option than Mars, just by virtue of the fact that we have gravity and an atmosphere. On Mars, a cracked bio-dome means everybody dies. On Earth, you could probably just go fix it.
Earth has:
- Gravity
- Much better temperatures compared to Mars
- A moderately-pressurized atmosphere
- Water (even if it's salty/polluted)
- TeMPOraL 8y agoI generally agree (and I'd add: magnetic field, more sunlight - not just for temperature, but also power generation), but come on, Mars does have gravity :).
- jononor 8y agoA thermonuclear war and the ensuing nuclear winter would shift the situation quite a bit. Which is not that far-fetched, we have the capability and have been dangerously close a couple of times. Earth might still have stronger fundamentals, but it is good to have options. And, perhaps more importantly, technology developed in pursuit of becoming a multi-planetary species might very well help here on earth too - both in our current development path and in case of disaster.
- vokep 8y agoIts not that Mars would be better or even equal, but that it would be a second chance, just in case.
