When I wrote ‘Death by Transactions‘, it didn’t start off being about banks and technology. It started off with wondering why people who will complain about all the overhead of small transactions don’t use the same concept to tie it to ecosystems.
Every breath we take is a transaction. In turn, every time photosynthesis dumps oxygen into the atmosphere, it’s a transaction. At one point, we probably had a lot more oxygen on the planet than we do now, which probably kept the plants from going too crazy. I think I saw something on that in a recent documentary about the planet.
Nowadays, we have more carbon dioxide, so the plants are probably having a great time – those that have survived us. They don’t breath as animals do though, but in principle they help keep a balance for us to breathe oxygen. We don’t hear about the flow rates of plants producing oxygen to the atmosphere and we humans exhaling our carbon dioxide all over the place (plus we DO love combustion, don’t we?).
It’s complicated to prove, but we humans are only a part of the carbon dioxide exhalers. It seems like almost everyone but the plants is putting out carbon dioxide, even little baby birds. The interesting thing is that in cycles, the plants also produce carbon dioxide.
We haven’t had an epidemic I know of with people with low pulse oximetry yet, where people are falling below the range of 90%-100%. We seem to be getting enough oxygen still, but of course by the time that falls it will likely be too late to do anything about it. When we look at the history of oxygenation on the planet, it’s pretty interesting.
Earth didn’t always have oxygen, which is before Earth was called Earth by a bunch of primates.
We seem to be doing ok, but some other species are not doing so good.
…The ocean stabilizes the atmosphere in two important ways—it contains plankton and bacteria that produce somewhere between 50 to 80% of the world’s oxygen,1 and its water absorbs massive amounts of carbon—about one-third of the amount humans have put into the air since the Industrial Age2—reducing the impact of fossil fuel combustion. As the planet gets hotter due to increased CO2 concentrations, oceans are also warming up. As liquids warm, they can’t hold as much dissolved gas. This means a warmer ocean can’t hold as much carbon or dissolved oxygen, which marine life relies on for survival…

Our planet has a history of warming and cooling. We know this, it’s no secret, and when the temperatures have shifted, extinctions happened, and new life popped up. Our planet is pretty volatile in that regard, but we don’t notice it because we live very short lives in comparison to the Earth.
We lose marine life, we start impacting non-marine life. You know. Ourselves. Some species will flourish, some won’t. We’re in uncharted territory. Here there be monsters.
If you think of every ancestor you ever had stringing back to the origins of humanity, that’s how many lifetimes we have managed to shove into our small time on this planet. 10,000 generations? 12,000? Either are guesstimates you can find on the web at the time of this writing. Humans have only been around 0.007% of the time the Earth has been swinging around the Sun.
If we work with the 10,000 generation number, that means our lifetime is only 0.000,000,7% of our time on the planet. (Can I use commas? I used commas. Count the zeroes). That means on average each one of us will have been around about 7 millionths of a percent of the age of Earth. For a while, at least.
In we got out of our own way and look at it as a planet, the planet is going through it’s own transactional cycles, and yes, we’re impacting it, which isn’t too much of a surprise because everything that has been trading oxygen and carbon dioxide has been doing so for millennia. This is the point many people make, and it’s valid except it forgets one very key thing. A somewhat important thing.
At some point, we won’t be around. And unlike any other bit of history of the planet Earth, we also can do things to help make sure that we are around.
But the Earth will be just fine.
