Shallow #SodaLakes show promise as cradles of life on Earth https://phys.org/news/2024-01-shallow-soda-lakes-cradles-life.html

Biogeochemical explanations for the world’s most phosphate-rich lake, an origin-of-life analog https://www.nature.com/articles/s43247-023-01192-8

"You have this seemingly dry salt flat, but there are nooks and crannies. And between the salt and the sediment there are little pockets of water that are really high in dissolved #phosphate. When could this happen on the #AncientEarth, in order to provide a cradle for the #OriginOfLife?"

[insert meme] "It's #humans".

"We've driven 20,000 years' worth of #ClimateChange in...170 years.

"...the chances of our #species existing are...so small, [we must] realize how lucky we are."

"...the #Earth [is] one body...#climates and #environments...are connected...how fragile that #ecosytem is."

These videos prove our existence is so improbable as to be a miracle.

We need to behave accordingly, or die

My thread on #PBS's #AncientEarth series has me thinking that #PHD #physicist #RebeccaSmethurst may be overly optimistic in her calculations regarding the possibility of there being life as we know it existing elsewhere in the #universe.

Learning how many flukes of #geology it's taken for life on #Earth to survive may leave only thousands of planets with life at all, fewer with beings with whom we might communicate.

We are currently recreating the conditions that led to the greatest mass #extinction in the history of our #planet, exponentially more destructive than the one that ended the 160 million year reign of #dinosaurs that came after.

While we're currently doing so on a much smaller scale, we are doing so at a much faster pace.

"...reminds us our home is a living, breathing #planet."

Yes, #Earth is alive, just as we are.

"Everything you know about the planet, everything that you think of when you look outside, is because of #plants [and #fungi]." #Symbiosis

No, #humans are absolutely not the dominant #organism here, and it was #Asteroids (not #Aliens).

"...everything you know [exists] because of plants."

"...the story of life is the story of our planet's changing #geography."

"Life and #rocks...They're totally interconnected, interdependent on each other."

"#Geology and #biology are entwined together in the formation of the #Earth."

If we are alive (we are) then so is our #planet.

Earth is literally more alive than every #plant, #animal, and #fungus because its dynamism is the source of all other life.

"How did our familiar blue sky – the thin, life-giving band of gasses protecting our planet – come to be?"

Every person who discusses #Terraforming other #planets strikes me as ignorantly arrogant.
