Is there more, (or less) matter on earth sequestered as a part of biological systems than there was at any(arbitrary) time in the past?


I realise I don't have a specific question, and was looking for a lesson of sorts on what is the footprint of life and will the new not come if the old doesn't die and dissolve(biologically atleast).

If you could suggest me good sources to study this, that would be great.

As written the answer to your question is almost certainly yes and no depending on those arbitrary times. Rewriting your question so that it is clearer, more focused, and indicates why you want this information is likely to get a better response. We also encourage you to do some research and then, informed by what you have learned, ask any questions you still have (ideally with references to reliable sources). Thanks! 😊 $\endgroup$ – tyersome Feb 7 at 18:02
  • $\begingroup$ All the coal, limestone, and other bio-deposited stuff on Earth attests to the fact that past life has left behind a giant, cumulative mass of modified matter. Even components of our atmosphere would be part of that mass. Some of all that gets recycled by living organisms, and some gets modified by geological processes so that it may be hard to distinguish from "non-biomodified" matter. $\endgroup$ – S.

  • $\begingroup$ @S.McGrew I am not talking about bio-modified matter as much as matter which forms the bodies etc. of living organisms. $\endgroup$ – Rohit Feb 21 at 14:30
  • $\begingroup$ Then that would include limestone, coal, & peat. Marble is metamorphosed limestone. $\endgroup$ – S. McGrew Feb 21 at 15:14
