No matter how politely one says it, we owe our existence to the farts of blue-green algae.
Look, Sage. I don't know much about chemistry or computer hacking or photosynthery, but this is something I've got a lot of experience with." I think he mean photosynthesis, but I didn't correct him. "Use my knowledge. Don't let it go to waste.
With the exception of autotrophic bacteria, the green, or chlorophyll-bearing, plants are the only living forms on this planet capable of synthesizing organic matter out of inorganic elements and simple compounds.
...the life of the planet began the long, slow process of modulating and regulating the physical conditions of the planet. The oxygen in today's atmosphere is almost entirely the result of photosynthetic living, which had its start with the appearance of blue-green algae among the microorganisms.
Consider the Lichen. Lichens are just about the hardiest visible organisms on Earth, but the least ambitious.
No human civilization could ever sever our dependence on photosynthesis.
The photosynthesis we see with plants is not very efficient. Algaes are more efficient.
Photosynthetic organisms in the sea yield most of the oxygen in the atmosphere, take up and store vast amounts of carbon dioxide, shape planetary chemistry, and hold the planet steady.
