Ancient microbial life on Mars could have destroyed the planet’s atmosphere through climate change, which ultimately led to its extinction, new research has suggested.
The new theory comes from a climate modeling study that simulated hydrogen-consuming, methane-producing microbes living on Mars roughly 3.7 billion years ago. At the time, atmospheric conditions were similar to those that existed on ancient Earth during the same period. But instead of creating an environment that would help them thrive and evolve, as happened on Earth, Martian microbes may have doomed themselves just as they were getting started, according to the study published Oct. 10 in the journal Nature Astronomy.
The model suggests that the reason life thrived on Earth and was doomed on Mars is because of the gas compositions of the two planets, and their relative distances from the sun. Being farther away from our star than Earth, Mars was more reliant on a potent fog of heat-trapping greenhouse gases, such as carbon dioxide and hydrogen, to maintain hospitable temperatures for life. So as ancient Martian microbes ate hydrogen (a potent greenhouse gas) and produced methane (a significant greenhouse gas on Earth but less potent than hydrogen) they slowly ate into their planet’s heat-trapping blanket, eventually making Mars so cold that it could no longer evolve complex life.
The scientists believe their findings suggest that life may not be innately self-sustaining in every conducive environment it pops up in, and that it can easily wipe itself out by accidentally destroying the foundations for its own existence.

When you look at all the things necessary for life, and the low probabilities of those things happening in the same place, I would not be surprised if we are the only living things in this vast universe
No it hasn’t. Still funny most of the time. Cheers
It does seem to be a very bad bet, if you’re a betting man.
Breaking news???
This passes as science?
What about Uranus?

It wasn’t mankind
I see what you did there. ;)
I bumped it up. too delicious not to. Sorry.
Wasn't a slam against the Bee. Was a slam against what passes for news now.

Lol
Ha!Ha!Ha!Ha!Ha!Ha!Ha!
Thank you that I won’t be the first to point out that satan only comes to steal, kill and destroy so is Mars a surprise? Read a little of Stephanie Relfe’s Mars Records and one’s reality might experience a bit of a shift. They hate tobacco, by the way, since they’re lizards. Convenient that the nicotine in tobacco is effective against Covid, and so is the propylene glycol in nic salt vapes, which leaves glycerin as the third ingredient. Wonder why they want to ban them? I don’t.
RE: The model suggests these people are the dumbest among us.
The absent minded professors who don’t know puppy droppings from Shinola.
Is this The Bee?
Mars is a sterile wasteland.
Well, Clearly the microbes didn’t have carbon taxes and Al Gore to save them.
They did, however, have AOC. She speaks their language.
This suggestion is already a certainty cemented into the hive mind of the woke web.
