What Would The Earth Be Like Without Photosynthesis?

[@kenmorris2228]

I knew an old gentleman who had worked in a quarry in South Wales. He told me of the time when they blasted a rock face and couldn’t believe their eyes. The entire quarry face was a fossilised forest of ancient trees some fifty to sixty feet tall and so tightly packed together they were like grass.

[@PyrusFlameborn]

Damn! So forests were more like a solid block of pure tree.

[@BellumCarroll]

@@PyrusFlameborn Maybe. Or they were packed tightly after being knocked down by a flood or volcanic blast, covered over and fossilized in that way. Over time the Earth shifts and makes them appear to be standing upright. Who knows.

Love this series. Wanna add: the reason we have these huge coal deposits from the Carboniferous is that fungi and bacteria took a long time to evolve the enzymes needed to break down cellulose. So not much chance was needed to fossilize early trees, hence huge coal deposits today.

[@acmenipponair]

Also these trees were in swamps and therefore fell into water when they died. The sediments then saved these trees from being consumed and they sedimented instead. And as soon as they had dried too much, they were not eatable anymore.

There was another form of photosynthesis that developped before the one that dominates today. Its color is purple, and it processes sulphur compounds instead of oxygen. Had chlorophyll not evolved to outcompete it, life on Earth would also have developped in a very different, yet possibly just as diverse way.

[@Pfh3dk]

Nice observation! However, oxygenic photosynthesis uses water as a source of electrons and hydrogen, a much more common raw material than sulphur compounds. If it was the dominant form of photosynthesis, life would be very different indeed, but I don't think it would be just as diverse. There wouldn't be enough resources to power ecosystems like the ones we have today.

@@markmitchell450 It's much easier to see what has come before, since plenty of evidence is left behind. Our skill at predicting the future should hold no bearing on our ability to research the past. As for the preservation of carbon, the reason the carbon has stayed locked within the plant material and later turned to coal is that, at the time, few if any organisms could break down woody tissues to release the trapped carbon. Wood didn't rot. For millions of years.

[@addysong1628]

Speaking of "The Entire History of the World Culminated in Country Music": As a young immature college kid 25 years ago, I once wrote a frosh philosophy paper attempting to demonstrate biological evolution and the rise of human technology and civilization were all a grand ontological project designed to reach a point where we had the technology and insight to create the movie Blade Runner. The biogenesis of life, the struggles, extinctions, and precarious survivals, life's innovative radiations and tight bottlenecks, our development of writing, history, psychology, the necessary chemistry, physics, and engineering for motion picture cameras, all our wars and tragedies -- all were part of the necessary grist to achieve what Immature Nate asserted was the pinnacle and ontological culmination of our entire terrestrial purpose: to finally have the equipment and wisdom to produce Blade Runner. I recall I got an irritated call to my dorm landline by an annoyed Texan Catholic philosophy prof. It was a long day.

i like your presentation of the topics. thank you for not screaming at us in the intro. 100 points in my yelp review for sure!

[@al35mm]

Just a heads up. Coal did not form because trees got buried. All coal formed during the same period because there was nothing that could break down the deadwood of those first ancient trees. It would be some time before fungi adapted to break down lignin which makes up wood. So dead wood would pile up on forest floors with nothing to break it down. It would gradually get buried and crushed. Coal no longer forms now because fungi are now very efficient at breaking down fallen trees.

[@PyrusFlameborn]

So once we use up our fossil fuel, that's it. There will never be fossil fuel again. This will happen because there is a finite amount.

[@SuperPickle15]

coal can still form, but it would take the right environment where the fungi can't survive, such as a peat bog.

Ecological diversity at hydro-thermal vents is incredible with large animals taking advantage of the food source, including vast fields of clams, octopuses, crustaceans and worms, even some fish are able to inhabit these depths and take advantage of this food source. This environment has complex ecological webs as complex, if not more then the majority of the ocean, due to the abundance of primary production. So while life would be very basic and rate, it would be able still in these environments to maintain similar ecological similarities.
