Cyanobacteria like this ball of slime have been around for at least 4.3 billion years - the most common forms were stromatolites - pretty much the only life forms except perhaps for other bacteria and viruses, generally confined to oceans and some lakes

I was going to stand up for cyanobacteria and whatever bryophyte was making spore tetrads at the Ordovician-Silurian boundary.

Viral infections of ocean cyanobacteria release nutrients that boost microbial growth, supporting oxygen-rich zones below the surface and linking viral activity to ecosystem productivity.
How marine viruses help fuel underwater oxygen-rich zones
Newly published interdisciplinary research led by the University of Tennessee, Knoxville, and University of Maryland shows that viral infection of blue-green algae in the ocean stimulates productivity in the ecosystem and contributes to a rich band of oxygen in the water.

Researchers have achieved a significant advance in recombinant protein expression within cyanobacteria, specifically Synechocystis sp. PCC 6803, by over-expressing human interferon α-2 fused with phycocyanin's CpcB subunit.

Estimated 100-125K years thermal max and ocean temp rise to deeper and deeper methane clathrate formations with stratification reaching the abyssals and the skies finally clear for cyanobacteria to restore the atmosphere for re-evolution of life. Don't hold your breath.

Lichens are a result of a symbiotic relationship of a fungus, a photosynthetic partner, either green algae or cyanobacteria, or both, & as recently discovered, bacteria. FYI, lichens are beneficial in their ecosystems & do not harm trees. Read: greengardeningmatters.blogspot.com/2020/11/lich...

To better understand why cyanobacteria cannot utilize the elevated CO2 intake we investigated the transcriptomic changes in model cyanobacterium:
lnkd.in/edRussCW
This knowledge is important to use cyanobacteria to capture carbon directly from industrial CO2 point sources such as flue gases.

you idiot, lichen is often confused with moss but is actually a hybrid colony of algae or cyanobacteria living symbiotically among filaments of multiple fungus species, along with bacteria[1][2] embedded in the cortex or "skin", in a mutualistic relationship.

Because the truth is that the way that animals serve humans is by serving all of.
For example whale poop fertilizes the oceans which leads to greater cyanobacteria that generate oxygen.
And penguins in Antarctica poop and sulfates from that reflect sunlight and help keep the ice from melting.

There are two #extinction scenarios today:
🟢 plants and fungi somehow make it. Only animals (consumers aka parasites) go extinct.
🔴 Even plants and fungi don't make it due to #cyanobacteria becoming dominant again
I hope for A but fear for B.

Technically speaking, some bacteria should be able to survive. Cyanobacteria for example. Cyanobacteria could restart everything again and who knows what may happen after 1.5 billion years? I'm not sure animals can make it. Some ferns and grasses maybe? There are too many toxins to bet on it imo.
