This was my comment just now. Let's see how the pro Musk crowd reacts. You'll note that I did NOT include my characterization of Musk as a charlatan, like I do here. Doing that is a guarantee, immediate/knee jerk reaction rejection of whatever it is you have to say for people that are huge Musk fans.
All I did was provide (mostly scientific) facts.

1. Musk claims he’ll have humans on Mars in the next 5 years. This is possible.
2. Musk claims that in 20 years or so that we will have 1 million people colonizing mars in SELF SUSTAINING fashion.
3. He claims that this will allow humans to escape our planet that we are destroying from the climate crisis because of too much CO2.
4. The amount of well mixed CO2 right now on our planet is just under 430 parts per million. The amount of atmospheric CO2 on mars is 950,000 parts per million. More than 2,000 times the level on earth.
5. Mars atmosphere is 95%+ CO2 and there is 0 oxygen.
6. There is no organic matter on the planet. Martian soil is toxic for plants and people because of the high level of perchlorates(chlorine)

7. The distance from the sun means that sunlight is too weak to conduct effective photosynthesis. Constant dust storms also block out the sun.
8. The average temperature on Mars is about minus 80 degrees Fahrenheit (minus 60 degrees Celsius), although it can vary from minus 195 F (minus 125 C) near the poles during the winter to as much as a comfortable 70 F (20 C) at midday near the equator.
9. Because there is no atmosphere and no magnetic field on mars, the amount of damaging radiation from the sun That bombards the surface is 700 times the level on earth.
10. it took almost a year to rescue a handful of people stuck in space just above the earth. Somehow, in 2 decades we will be able to get 1 million people on mars using the same technology. Mars is 50 millions miles away,. 200 times farther than the moon.
12. Even if this were possible , the cost would be in many trillions….but it’s NOT possible.
Musk is an extremely brilliant man, especially in marketing.
He uses this Mars colonization fairy tale to help generate government funding/secure costly government contracts and to attract gullible investors.

Someone, thanks very much for the correction. That was a typing error, missing the last 0. That should have been 200 times farther and as you showed, that varies tremendously.

Yes!
I should have also added that the amount of well mixed CO2 right now on our planet of just under 430 parts per million is less than half the optimal level for most life, which is closer to 900 ppm.
Going from a garden paradise in the Goldilocks zone, with near perfect conditions for almost every metric needed for life here on earth, especially as earth greens up from the increase in beneficial CO2 to a hell hole that lacks almost everything needed for life at a cost of multi-trillion dollars….supposedly to escape the garden paradise is a messed up mentality.
