About 250M years ago, 90% of species on Earth died during the Permian extinction. All of that loss created a lot of vacant niches to fill. And not long after, the first mammals, our ancestors, appeared.

Life on this pale blue dot will continue to be resilient - whether or not we’re part of it. #Thanksgiving #science #history

this is setting a pretty low bar for optimism isn't it? It's like putting a skipping rope on the ground and calling it the high jump. First the fossil fuel industry encouraged us to think there was no problem and now it's encouraging us to believe there's nothing we can do about it anyway. I'm firmly in between. There is *plenty* to be done, and no reason to roll over and accept mass extinction as a done deal. How do I know? Where I live there used to be almost no humpback whales. Now more than 40,000 migrate past here each year, and growing - thanks entirely to activists who wouldn't give up. And just this Friday there was a mass demonstration run by school kids, a new generation putting adults to shame for their complacent fatalism. Yes, in the long run we're all dead, and nature will continue without us. But until then: action, not acquiescence.

In that vein, I recently finished reading Beasts Before Us by Elsa Panciroli, and it sorta begins where your post ends, with the end-Permian extinction and the rise of our synapsid ancestors, etc.

It also does a good job of explaining how diverse mammals have been as a clade, not just the groups we see today, but the vast diversity that existed in-between, the marsupials' metatherian cousins or the wild variety of Cretacious mammal niches.

In the name greed humanity has sold its soul and its future.

ah okay, all‘s well that ends well, so let’s just carry on in our habitual ways until we’re all dead - is that what you’re saying?

I hope not. I don’t think we have the right to destroy the home of all our fellow species, thereby killing most of them, even if we were all okay with a collective suicide, which I’m not.

it is postulated that the current Holocene Extinction has a background Extinction rate similar to or perhaps greater than the PT event. If the Holocene Event, caused by man, continues unabated then it will rival the PT Event in magnitude.

Certainly not a proponent of his every statement, however George Carlin was fairly succinct in laying out that however much we destroy this planet, what we are destroying is this planet’s comfort zones for humans, not the planet itself. The planet will be fine. We, are fucked.

TWW: While you may visit other places, other realms, this is the people’s world for as long as you can hold it. *Even closer for us are the two glacial periods we survived while migrating to everywhere. I see us mitigating the massive amount pollution caused by industry and surviving the atmospheric and oceanic turmoil here at the end of this interglacial period. It will be a more advanced and cohesive people that face the next glacial period. Strength in Kindness. OWOP

We will begin to change to living in small, high-tech (small science, though; no particle accelerators or reactors here) agrarian communities pre-apocalyptically (potentially avoiding disaster) or we will do so haphazardly post-apocalyptically. We will almost certainly not do the former - achieving that would require cultural engineering. How many "cultural engineers" do you know? The ones that brought you these world-destroying cultures?

Beautiful words, but past results do not guarantee future results. A runaway greenhouse effect could be forever persistent, ending the possibilities for life except some primitive life forms.

Nature is a few 100 billion light years across and expanding. Nature will be fine, even if we do destroy this, the only known habitable planet. I recommend we don’t btw
in reply to Sheril Kirshenbaum

Rather optimistic. There's a good chance the next extinction event - our climate apocalypse - might turn the planet into a heatsink hell like Venus. Nothing will survive that.
Nothing.
in reply to Sheril Kirshenbaum

But of course… more people should realize this… Earth just gave us a chance, if we ruin it we will just be gone, and Earth moves on…
in reply to Sheril Kirshenbaum

I find this perspective comforting. Nevertheless, the period of the planet's biological history that most interests me is the ~70-100 years I am likely to be alive.

I volunteered on a couple dinosaur digs a long time ago and I asked the paleontologists there if they thought humans would be around in a million years. To a one they said "nope".

Chipping out a baby Parasaurolophus skull from solid rock, it was easy to imagine the wave upon wave of fabulous creatures that once roamed the earth at one time or another, only to become fossils by the time the next ones were leaving footprints in the sediments above them. In the future, in a length of time from now that is barely a rounding error in the last 4 billion years, Earth will be covered with another unimaginably weird and wild menagerie.

We're just messing it up for ourselves and the other creatures here at the moment. We could nuke ourselves 50 times over and the ecosystem from undersea vents would take over in a million years or two.

The idea that we're awesome enough to destroy the world is the same hubris that will lead us to destroy ourselves instead.

We don’t need religion to recognize what a miracle it is that we arrived here, in this moment, at all. ✨ /2
in reply to Sheril Kirshenbaum

We don’t even need religion to share and trust in life… 🍀🌹
in reply to Sheril Kirshenbaum

Agreed! Miracles are real with no human intervention. Religion is man made.
in reply to Sheril Kirshenbaum

we probly need something LIKE religion to help us remember to pay attention to that miracle. i think most of us don't take so much opportunity to sit back from the slog of life to pay attention to such miracles.

i would call science (a very organized social process) a tradition similar to religion in this respect.

religion does not need a god nor supernatural. just practices in the attention on what life IS.
