How Plants Turned Air Into Civilization |The Calvin Cycle
Показать описание
The Calvin Cycle is how we transform carbon dioxide into--well--everything. By making carbon biologically useful, our biosphere has managed to transform CO2, Sunlight and water into basically the entire world around you. Does that sound hyperbolic? Watch to find out just how much of an understatement that really is.
The Calvin Cycle is the molecular process that built our world. This final step of photosynthesis evolved 3.8 billion years ago and has been changing everything for our biosphere ever since. Photosynthesis is how energy enters our biosphere--but the Calvin Cycle is how our world stores that energy. Energy is pretty useless unless you can store it. You'll see in this video how that principle also unlocks the key to building civilization. Sure, humans did pretty great as hunter-gatherers--but as soon as we figured out how to store excess food and build surpluses--that was the edge we needed to build civilization. And then--the hydrocarbons that helped power that civilization to it's current heights (and that are putting it on the brink of disaster) were made across eons through this exact same process. Our whole world comes down to this molecular cycle. No fixed carbon. No Us. No civilization.
