Mars has no magnetosphere to protect from radiation and the atmosphere is extremely thin, a "luscious green planet" is a fantasy.

Silly boy...Musk is going to contract that Core team to dig their way down to Mars's core and restart it spinning. That'll fix it!!!

At least you now know what the wind blowing on Mars sounds like. If nothing else, it was worth it just to be able to hear that.

Ancient life may be just one possible explanation for Mars rover's latest discovery


In the news.
A new analysis of sediment samples collected by the rover revealed the presence of carbon -- and the possible existence of ancient life on the red planet is just one potential explanation for why it may be there.

I have this eerie feeling that decades from now it will be determined there was indeed civilized life on Mars. Advanced life. Advanced human life. And things got very much out of hand, technology wise, where the planet was destroyed by some catastrophic technological event of mass proportion. Technology so far advanced that the potential of complete destruction was not only possible but inedible. Pretty much as with our Earth of today, where as our technology advances it is our Earth that suffers because we don't care and refuse to prepare.
Progress and profit trumps precaution and prevention. We think the Earth as indestructible, but what happens 200 years from now, 500 years from now, 1000 year from now when our technology has advanced to the point of no turning back? When that day comes, what do we say to humanity...? Whoopsie? My bad? The Earth destroyed in its entirety, and all within seconds.

So, how did humans arrive here on Earth?
Last minute escape? Experimental life that evolved into human? Could humans on Mars have advanced to the point where the humans on Earth "were" the experiment? And after technology on Mars got so out of hand, we here on Earth are all that remains?
Are we humans now residing on this Earth doomed to repeat what happened on Mars? 1000 years from now, could Earth be nothing more than red dust, wind, minus our atmosphere?

Is THIS the Earth of tomorrow?

It's prettty well understood how Mars got the way it is, it's interior cooled enough for it to lose it's magnetosphere thus rendering it's atmosphere hit by the solar wind, eventually most of the water evaporated into the thinning atmosphere and was lost too.
